The SOLAR KNOWLEDGE database opened to the public on 02-10-18, information uploaded weekly.
More and more homes, offices and devices are now relying on solar power as people are becoming more aware of the potential dangers of other unnatural sources of power. It is important that you know more about the idea to determine if it is the best option for you. Solar power can render several benefits for the long term. You can take advantage of the features by choosing the right type and maximizing the effect right in your own home.
Solar power is described as the creation of electricity straight from the sun. The generation can be direct with the use of PV or photovoltaics or indirect via CSP or concentrating solar power. CSP is done by using the energy of the sun to focus and boil water which will eventually create solar power. Solar power has the capacity to give more than 1000 times the total world energy consumption back in 2008. However, solar power only comprised 0.02% of the total in 2008. If solar power will be used double every 2 to 3 years, it can become the dominate source of energy for the century. The biggest solar power plants, are concentrating solar thermal plants, although new multi-megawatt photovoltaic plants have also been created. More and more countries are investing in the bigger photovoltaic power stations, like Germany and Portugal.
Terrestrial solar power is a predictable and intermittent source of energy, which means even though solar power is not readily available all the time, people can still predict it using a certain degree of accuracy when the energy source will or will not be available. A number of technologies, like the solar thermal concentrators, include an element of thermal storage, such as molten salts. These come in the form of heat and are considered as store spare solar energy that can readily be made available overnight or at times when solar power is not available to create electricity. Orbital solar power collection also avoids the intermittent use, although satellite launching and beaming of the gathered power are required to get antennas on Earth. The enhanced intensity of the sunlight over the atmosphere also tends to boost the generation efficiency.
Solar energy, heat and radiant light that emanates from the sun have been controlled by humans beginning the ancient periods using a wide range of evolving technologies. Solar radiation, together with secondary solar-powered resources like biomass, wind, wave and hydroelectricity are accountable for majority of the available renewable energy on Earth. Only a small fraction of the available solar energy is utilized. Solar powered electrical generation depends on photovoltaics and heat engines. The uses of solar energy are only limited by human ingenuity. Some of the other uses of solar energy include space cooling and heating via solar architecture, solar hot water, solar cooking, potable water via distillation and disinfection, daylighting and high temperature process heat for industrial functions. Solar panels are one of the most effective and basic ways to gather solar energy.

There are two kinds of solar energy according to how the energy is converted. Active solar energy is defined as creating energy with the help of mechanical devices. Passive solar energy does not require the use of mechanical devices and provides you the advantage of getting energy nonstop and in a more cost-effective manner. Passive solar energy is further divided into different categories. Here are some more tips and guidelines on the kind.
There are a number of principles that you have to keep in mind to take advantage of passive solar energy fully. The applications will rely on the specific location and climate you belong to. Orientation refers to the positioning of the home so that you get most of the sun's rays to heat and minimize the impact for cooling. Shading is vital in managing the natural light and temperature of the home. Shade can be given by other structural elements. Insulation refers to keeping a warm home during the winter and a cool house during the summer. Thermal mass refers to heat storage during daytime and its release after the sun is gone. The windows will make sure that the home stays comfortable any day of the year. Ventilation refers to maintaining the cool inside the home during extra hot days.
Passive solar heating belongs to the category of solar space heating. The heating process can be done by orienting the home well so that most of the windows face to the south. The windows should be sized properly too, so that optimal heat gain will be attained. The home has to be insulated to reduce loss of heat. Passive cooling is a kind of solar cooling. The main idea behind passive cooling is to reduce the impact of the sun by orienting the landscape and the house so that you get the most benefits out of cool breezes. The home also has to be designed to reduce barriers to air paths through the home to let natural ventilation in. You need to use the right type and size of windows to reduce the heat during extra hot days. Landscaping and structural features can be used to make shade. The home also has to be insulated well to keep the right temperature.
Daylighting is a kind of solar energy lighting. It is described as the use of natural light to illuminate the house. Good daylighting provides the right light to all your rooms, while minimizing costs in utilities and electricity. You can daylight the house well by sizing and positioning the windows so that natural light freely enters the home. You should also use exterior shading that will diffuse the light. Passive solar energy is considered as a natural and very cost-effective way to maintain your home. You can save so much in the long run and expect to have the right light and temperature inside your home for years to come. Talk to experts on how you can install the right elements.

Solar energy is present in different kinds. This is categorized according to the manner of conversion, as well as the type of energy that it gets converted into. It is important that you learn more about the types so that you can see how much energy you will need for your setup. The levels and features will also differ based on the type. Knowing the categories will help you determine if it is wise to pick a certain system or not. Here is some more info.
The first way to view solar energy will depend on how the energy is transformed into useful energy. There are a couple of types in this category - passive solar energy and active solar energy. Passive solar energy describes the harnessing of the energy of the sun without the need for mechanical devices. You can use windows that face south to give you natural light and additional heat for the home. There are many solar applications that a homeowner can rely on to get the most benefits out of passive solar energy like passive cooling, passive solar heating and daylighting. Active solar energy involves the use of mechanical devices in collecting, storing and distributing solar energy inside the home. Pumps, for example, are used in active solar energy water heating systems to circulate the water through the system. There are plenty of solar applications that a homeowner can use to get the most out of active solar energy. Included are active solar space heating, active solar pool heating and active solar water heating.
According to Energy Type
The second means of viewing solar energy relies on the kind of energy that it converts into. There are 3 kinds that belong in this category namely photovoltaic solar power, solar thermal energy and concentrating solar power. Active solar space heating is done to heat the air within the house. It uses mechanical tools and equipment like fans, pumps and blowers to help people gather, store and distribute the heat all over the home. The systems can be air-based or liquid-based. Liquid-based systems involve the use of large water tanks or thermal mass for the storage of heat. Distribution is managed through radiant slab systems, hot-water baseboards and central forced air systems. Air-based systems involve rock bins or thermal mass that hold the heated air for storing. The hot air is circulated within the home using blowers and ducts.
Solar thermal energy is the energy made by transforming solar energy into heat. There are plenty of solar applications that a homeowner can use to get the many benefits of solar thermal energy, such as solar space heating, solar pool heating, solar water heating and solar thermal cooling. Photovoltaic solar power is described as the energy made by converting solar power into electricity via photovoltaic solar cells. There are many solar applications that homeowners can take advantage of using photovoltaic power like solar electricity, photovoltaic solar lighting and photovoltaic cooling. Concentrating solar power or CSP is used to create solar power electricity.

Electric systems have been created because of the rise of solar power as a reliable and cheap source of energy. There are now different techniques, methods and systems that depend on solar power to run plants, houses and offices effectively. You should learn more about these systems to determine the best types that will provide you with the most benefits. You can choose to make your own or just purchase one from top manufacturers.
There are small stand-alone electric systems that are very good at giving economical electricity. These systems are mainly used to power RV, lighting, backup power systems, portable power systems and cabins. The size of the array of photovoltaics or the number of solar panels, as well as the battery will rely on the individual power requirements. The solar panels charge the battery during daylight periods and the battery will provide power to the inverter whenever required. The inverter transforms the 12 volt batteries DC power into 120 volt AC power. This is the most useful kind of current for majority of applications. The charge controller will terminate the charging once the battery reaches the full charge. The batteries will not gas out this way and battery longevity is enhanced.
The grid-tie solar system is very useful for homes that are already linked to the utility grid. The primary advantage of this kind of system is the cheap price of utility. The system needs to be wired with an inverter that creates pure-sine-wave AC electricity, which is needed for linking to the utility grid. Another benefit of this electric system type is the tax incentives. There are also rebates provided depending on the local agency and the state. If you own a grid-tied system in California, you can make use of some programs that will minimize the total cost of the system. Majority of the system usually do not include the battery storage that lets power in once the utility does not work. Grid-tie systems are installed using battery backup power to maintain critical loads even in the presence of a power failure.
The complete or full stand-alone system is very useful for complete independence from electric utility companies and fossil fuels. The benefit of the system is the capacity to provide power away from the utility, as well as creating a measure of self independence. The complete stand-alone home solar system will usually have a couple of inverters to supply the AC house current needed to power very big loads like air conditioners. An available second inverter will help make sure that power is present if one of the inverters will need servicing. Self-contained systems like these require an adequate battery keeping capacity to give electricity when solar power is not available because of prolonged adverse weather conditions. The complete stand-alone system usually needs 20 solar panels for safe battery keeping and adequate charging. You may ask an expert to help you decide between systems to that you get the most out of your investment.

When people talk about solar energy, all they really talk about is how much this alternative form of energy source is a great source for power and electricity, and how this source of energy can help you save a lot on your utility bills. However, there are certain things and aspects about solar energy that should be discussed with people, especially since solar energy is now being integrated in constructing modern day houses and structures, and are even now becoming a viable source for power and electricity. One of those things that should be discussed involves the risk of using solar energy. This article will try to present to you some facts and information about the risks involved in using solar energy. Before we can discuss more about the different risks, let us first discuss what solar energy is, and how it is produced in order to understand its different risks.
For those of you who don’t know, solar energy is actually produced from a process that occurs within the sun known as nuclear fusion. Nuclear fusion is actually the very same process that is involved in nuclear power plants, and actually employs the same basic nuclear physics laws that applies to atomic bombs. This is definitely a major cause for alarm for most people. Aside from that, add the fact that the main energy source for solar energy is actually hydrogen, which is a form of gas that is highly explosive, and that is definitely something that you should be aware of. Hydrogen is a tremendously destructive component that can be found in H-bombs, and also produces dangerous fallout for those exposed. These known dangers of solar energy may sound very threatening, but these are not the only things that you should be worried about, for solar energy could also have other not so well-known dangers that could pose a risk to your health.
Right now, we are all actually being subjected to the sun’s background radiation, which could be dangerous if exposure to it exceeded a certain level. There is really nothing we can do to prevent being exposed to such background radiation other than to simply avoid sun exposure. However, if your home uses solar energy to power up your house, you might find it more difficult to do. Since solar energy technology harnesses the power of the sun by concentrating the sunlight, and using its energy to light up your home’s light bulb, you could very well be irradiating your entire home, something which could cause skin cancer later on.
Another danger that could stem from using solar energy to power up your different gadgets and electronics at home is that it could cause blindness if you were to expose your eyes to too much radiation from them, just like staring directly at the sun for too long.
Since most solar collectors basically concentrate the sunlight that they are able to collect from the sun, it can be a fire hazard, especially since fire can very easily start if there were very high concentrations and levels of solar energy. These high and dangerous levels of solar concentrations could easily ignite combustible materials, making it a possible hire hazard on any home. These are just some of the risks that solar energy could pose on you, so make sure that you do some researching first before deciding on whether you want to get and use solar energy technology for your home or not.

Pros and Cons of Solar Power
The advantages of solar energy continue to grow with more pros and experts learning more about the process and features. Of course, there are also a number of consequences especially for the person who does not study much about the devices. It is important that you weigh the potential of having your own setup. You should consider the things you need to power, your location, budget, etc. Here are some more details about the energy.
The good thing about solar energy is that it can be used anytime or as long as the sun exists. You can get the power you need day in and day out. Solar power is a renewable resource which means that you do not have to pay any bill or keep replacing parts to get the results that you need. The disadvantage in terms of availability is that you cannot access the energy if there is no sunlight. You cannot rely on solar power at night or in places that tend to be very cloudy for several months. People living in tropical areas or desert regions can rely on solar panels. However, those who experience very long winter months may not get the best effects.
Nowadays, solar energy can power a variety of objects such as homes, offices, cars, small light fixtures, toys and calculators. You can now rely on the sun to help you minimize utility and electric bills. You can even see a number of vehicles now solely powered by the sun. The disadvantage to the approach is that the power may tend to fluctuate depending on the sunlight available. Some devices may not work as well if the acquired energy from the sun is insufficient. In some cases, power may totally fail if solar energy is limited or unavailable.
Even though solar cell panels are readily available in most hardware stores and the internet, not everyone is still capable of installing the devices properly. The initial setup costs may be very expensive for some individuals. Women may especially find that tasks hard to do unless they rely on a professional to do all the work. Installation will depend on several factors and will need careful study, such as the angle of the sun, the position and area where you need to place the solar panels and the number of hours to complete the project.
Purchasing solar power systems may be more expensive for first-time buyers. Those who have been used to the old system may have to spend more initially. Overall, the cost for maintenance begins to taper down because the sun is readily available and free. Some people, especially those coming from the third world countries may not have available solar cell panels ready for purchase. They may have to order online. The professionals needed to install and maintain the system may not also be available in some areas. The fees, if ever, might be more expensive. You have to compare the options first.

Solar Energy and Photovoltaics

Photovoltaics are considered an integral part of solar energy technology. PVs are now used in a wide array of settings, depending on the current needs of the user. More and more people around the globe are also starting to invest in these devices for a variety of reasons. You can get constant and renewable energy at a much cheaper cost, thereby power different devices and tools for your benefit. Here are some more tips and details.
The PV or photovoltaic cell is also known as the solar cell. It is a device that readily converts light into electric current via the photoelectric effect. The device is based on the discovery of Alexandre-Edmond Becquerel who realized that a number of materials let go of electrons when these hit rays of photos straight from light, causing an electrical current. The first solar cells were made by Charles Fritts during the 1880s. Even though the prototype selenium cells converted below 1% of incident light into electricity, James Clerk Maxwell and Ernst Werner von Siemens realized the importance of the finding. After the work of Russell Ohl during the 1940s, Calvin Fuller, Gerald Pearson and Daryl Chapin made the silicon solar cell in 1954. These were the early solar cells that were very expensive and can reach efficiencies of around 4.5% to 6%. The highest efficiency PV cells produced were by Boeing and SpectroLab in 2009, with efficiencies of around 35% to 41%. There are also other multi-layer cells that closely resembled the device. These were very expensive too, and were only used in the most unique applications. Thin film PV cells were also created and made in bulk. These were more cost-effective and less fragile, with about 20% efficiency.
There are several technologies now, including a minimum of 14 photovoltaic cell types, like polycrystalline silicon, thin film, monocrystalline silicon and amorphous cells. Concentrating solar power also appeared in several types. The earliest application of solar cells considered to be very significant was being a back-up power source to the Vanguard satelilite back in 1958. The solar cells continued transmission for more than a year after the chemical battery exhaustion. The operation of solar cells during the mission was considered to be very successful and was duplicated in several American and Soviet satellites. PV has become the established power source by the late 1960s.
Today, Germany has become the primary PV market worldwide after they revised the feed-in tariffs for the Renewable Energy Sources Act. Spain has become the biggest PV market after 2007 after it adopted the same feed-in tariff structure. Spain installed half of the PVs all over the globe, accounting for about 45%. Concentrating photovoltaics are very new, which employ sunlight concentrated onto photovoltaic surfaces for electrical power production. Solar concentrators of different varieties can be used. These are usually mounted on a solar tracker to keep the focal point on the cell as the sun travels over the sky. Tracking can boost the output of flat panel photovoltaic by 20% during the winter and as much as 50% during summer.

Solar Energy in the Home and at Work

Solar energy actually has a lot of different uses and applications to your home and your work place, and it also offers a lot of different advantages. Since solar energy is now becoming more and more affordable, as compared before, it is now more sustainable to have it in your home and at your work place. Here are just some of the possible advantages of using solar energy.
One of the more common uses of solar energy is for solar hot water heaters. Most homes in America actually have a hot water heater, which is probably why it accounts for about a quarter of the total energy consumption of a typical American home. Unfortunately, the U.S. government actually spends a lot of money on paying off the energy consumed by these hot water heaters, about $13 billion every year, possibly making it the single biggest energy consumer in your home or work place. Solar energy systems used on hot water heaters can actually help you save a considerable percentage on your utility bills, over 85% of the total electric water heating cost of your home. This is probably why a majority of the people who decided to invest in the solar hot water heating systems think that this is a wise decision indeed.
Solar energy or electricity is actually derived from certain solar energy technology and photovoltaic solar technology that allows you to convert solar heat into reusable energy, allowing you to get power and electricity in your home and work place. At this day and age, there are actually over 200,000 homes that use solar energy technology, 10,000 of which are powered solely by solar energy. And with the introduction of different photovoltaic integrated products, and incorporating them into the construction of your home, or your work place, you can actually save a lot just from the initial cost of construction as compared to building a conventional custom house.
If your home, or work place, has a pool, then a solar pool heater is needed to keep that pool heated at a certain temperature. Solar energy is actually being used by over 300,000 pools in the U.S., and could dramatically lower your utility bill by a considerable amount.
Net metering is actually a means for people who use solar energy to power up their homes or work place to be able to sell back to the utility company whatever excess electricity that their home or work place is able to produce using solar energy technology, but is not able to use up. This means that you will be able to lower down the cost of your power and energy consumption, especially since you have another alternative source for getting your electricity.
Also, people will soon be able to choose where they want to get their electricity from. They could either get it from their conventional utility, or get their clean power from a source that is non-polluting, but is just a bit more expensive than your conventional utility.

Solar Energy in the House

Solar energy is described as power coming from sunlight. It is a very economical way of getting energy needed for different household tools and devices such as lighting, power tools, appliances and other gadgets. You can save more in the next few decades by investing in solar power. You have to know the different types of setups and the things you need to consider before you choose to purchase and install. Here are some proven tips.
Solar panels are primarily installed on a flat surface such as the roof of the house. This ensures that the panels get and absorb enough sunlight to power the different items inside the home. As soon as the solar panels are activated, these will absorb the rays of the sun. The panels are made of semi-conductors like silicone. Electrons are then released from the atoms to produce electricity. The photovoltaic effect is achieved when light is converted into electricity. You can then have direct current electricity. When the power enters an inverter, you can get 120 volt AC conversion, the same electricity required to power the house. The connection will be to the utility panel so that appliances and lights will work the same way when the switch is turned on.
If the house is not using a lot of electricity from the solar energy created, the excess energy can be stored in a battery. When the sun is out, during night time or in the case of a power shortage or outage, the battery can be used to power different items in the home. If the battery becomes full, the extra electricity will be exported to the utility grid if the system is linked to it. Once the solar energy runs out, electricity coming from the utility will take over. The flow of solar energy electricity is measured via a utility meter that spins forward and backward. The meter will move backward if more energy is produced than needed and the meter will move forward when extra power is required from the utility company. The two are only even when additional energy is paid for from the utility company. The surplus will go straight back to net metering. The smaller version can power a water heater in the house. Homeowners can also get the same effect by simply converting sunlight into heat.
The good thing about solar energy installed for homes is that the system is very efficient and environmentally friendly. You can let your kids go to different areas of the house without having to worry about pollution and poisoning. Getting a system also means that you are saving the surroundings from stress and other pollutants in the years to come. You can get a cooler and cleaner environment by investing in a solar power system. You may choose to get a DIY kit or just have a professional install the system. Make sure that you properly position the panels to get the most sunlight and get maximum conversion.

Is Your Home Right To Setup A Solar Energy System?

In these modern times, it is not necessary to have a lot of land if you want to go solar. Nearly every home or business can now take advantage switching to solar energy. Continue reading for greater insight into the ups and downs of solar energy. The amount of energy produced depends on the efficiency of your solar panels as well as the number of solar panels installed. Therefore, determine the number of panels you need. Many times it is more cost efficient to purchase energy efficient panels rather than more panels. There are a couple of different photo-voltaic panels to choose from. Poly-crystalline panels are cheaper, and mono-crystalline panels are more efficient. When choosing solar energy supplies for your home, look for the most energy-efficient materials available. When using solar energy for the first time, it's probably a good idea to start out small. Purchase a couple solar energy landscape lights. You can find them at your local hardware store or mass market retailer. Installation is as simple as placing them in the ground along your walkway. The efficiency of your solar panels will be dependent on their density. Panels with a higher density are usually more expensive but their cost is justified since you will be able to produce a lot more power with these more performing products. Be sure and compare densities before choosing a solar panel. To gain more from solar panels for a business or home, get installations that have technologies that don't directly rely on our sun's schedule. Newer panels allow you to store energy and use it later when there are no sun rays. This can be quite useful if you use power at night.
Efficient solar panels are able to be moved. If you need to install panels that are fixed, a compromise will need to be reached in terms of optimal angles for winter and summer. Try to stay away from high pressure salespeople when scouting solar energy. Take all the time you need to ask questions, do some research and compare different options before investing in a solar energy system. Don't fall victim to pushy sales tactics, as this could cost you both time and money. After your solar panels are installed, check the inverter on a regular basis. You need to see a green light that's solid. If it is off or blinking, you should call your solar energy company. Most homeowners should not diagnose an issue with solar panels. If you have a warranty on the panels, you shouldn't have to pay for someone to look at it.
There is no need to hook your solar power system onto a power grid in your area. You are able to operate independently, something your family may really prefer. In other words, you won't need to change electric services should you move, nor will you see high electric bills anymore. You need to think seriously about the benefits of a good solar water heater. While even the most powerful versions generate efficiencies one-third above electric ones, they are still worthwhile. Second, don't assume showers in the dark morning mean cold water. Usually, water heated from a solar system will still be warm for about one day.
You can clean your panels yourself, but make sure to have someone out once or twice during the year to look them over. Get a professional to check the connections and level of damage to your unit. Consider leasing if you cannot afford the purchase solar of energy systems for your home. Leasing a system saves you money, and you can usually recoup the installation costs within a matter of weeks. Remember that you don't have to put your solar panels on the roof of your home or business. If you have land or yard space to spare, there are more options. Systems that track the sun or adjustable panel mounts can provide more energy. If you want to use less space and maximize your exposure to the sun, consider using your roof. To help optimize your savings, consider using a grid tied system. If your system produces a surplus of energy, you can sell that energy to the power company that owns the grid. This will help offset system installation costs, which results in your investment paying for itself even faster. Energy bills for a growing family can be high. Kids use many electronic devices, like their mobile phones, computers, and televisions, and it can be quite a challenge to get them to remember to save energy. Solar panels are a great way to cut out high energy bills. Solar energy can do so much for a family or business, from saving potentially thousands on utility bills to greatly reducing the amount of carbon-based pollutants emitted every year. If solar power is something that you think can help you, get started as soon as possible. Use what this article has taught you, and you should have no trouble utilizing solar power effectively.

Advantages of solar energy

For years we humans have been exhausting the resources of fossil fuels and have been causing a great deal of damage to the environment, and it is now time that we look at alternative energy sources to stop or even reverse some of the damage that we have caused. That is where solar energy comes in. Solar energy uses the power of the sun to provide energy and electricity to all its inhabitants. There are a number of advantages of solar energy and these include such things as it is free, vast and friendly to the environment.
One of the main advantages of solar energy is that it is abundant and widely available. One scientist has actually said that everyday the sun generates more energy than the six billion people who live on earth would use in more than 30 years. The sun will never stop shining – it is a huge star millions of miles away, and we will always be able to get energy from the sun. The sun provides the energy for practically all life on earth and keeps the planet warm enough for all this to exist. Despite the clear advantages of solar energy, the impact of solar power on society has been very small – less than 0.05% of the nation’s electricity comes from solar generating stations.
One of the other clear advantages of solar energy is that it is friendly to the environment. Burning fossil fuels causes smog, acid rain, global warming and other forms of pollution and because of this we need to cut down on the amount of fossil fuels used. If you want to understand how damaging the burning of fossil fuels is to the environment, you should watch Al Gore’s documentary on climate change – once you have watched this documentary you will be stunned and will never want to switch on another light switch ever again and will want to switch fully to solar energy.
Another of the real advantages of solar energy is the low cost involved. First of all, sunlight is free so when you install solar energy you will not have to pay for a kilowatt of electricity ever again. Although there are costs involved with the initial setting up of solar energy, you will actually be saving a lot of money in the long run. It is becoming even more affordable to set up solar energy technologies now because the government offers incentives if you use solar energy. Probably the most publicized incentive is the Energy Policy Act 2005 where you receive a tax credit if you use clean energy to power your household. The act provided tax credits aimed at reducing the cost of building solar power plants and because of this, a number of solar energy plants are being brought in - the solar industry is going through a big growth spurt just like the wind power industry.
By cutting down on the amount of fossil fuels burned and using energy alternatives such as solar energy, health risks will be reduced as well. Many people underestimate the damage that continual burning of fossil fuels is doing to the health of our plants, animals, and to us human beings. Therefore one of the many advantages of solar energy is a decrease in health costs. You probably have noticed that over the past 20 years or so the number of people developing diseases and cancer has increased ten-fold – a lot of this can be blamed on the burning of fossil fuels releasing sulphur dioxide into the air.

All About Solar Panels

Solar panels are now widely available all over the globe. You will find several homes, commercial buildings and vehicles relying mainly on solar panels to generate the electricity they need. Solar panels can also be made independently by the user. You can save more in costs by building your own system. You can also invest in a ready-made design for added ease and convenience. Here are some more tips and tricks on how to begin.

If you choose to use solar panels, you can produce electricity that can power various applications. Off-grid living means residing in a location where the main electric utility grid does not service your home or office. There are remote cabins and homes that can benefit from solar power systems. It is no longer needed to pay huge bills to install electric utility posts and cabling from the nearest grid access main point. A solar electric system is less expensive and can give you power for up to 30 years if you maintain it well. Solar power is also a renewable source of energy, which means that it is very clean. Today, it is more important to invest in devices that do not damage the environment and atmosphere. Solar panels do not have any moving parts and will need only minimal maintenance. As soon as the system has paid for its initial installation costs, you can get the benefits for several decades more for free.
There are plenty of places where you can buy the best solar panel models. You can choose between brands such as Sharp, BP Solar and General Electric. You should visit some of the manufacturer web sites to determine the process and the ways how their solar panels are built. You should also read about the background of the company and what their objectives are in making these pieces. You should read more about installation to check if you want to install or build the panels yourself or hire a professional. There are several web sites, online forums and internet stores where you can learn more about the available models and how these can best suit your location. Some panels are intended for individuals living in places that has minimal sun, while other designs are specifically made to gather the most sun over the shortest span of time.
Learn how to compare between types to know how much you need to pay for. The prices of the solar panels will vary depending on the brand and the size. There are also other factors to consider such as maintenance and if the package includes free installation. Some companies will ask for fees to install the panels, while other buyers may opt to install these themselves to save more. Talk to other people who have already tried certain makes and brands and let them give you the pros and cons of each. Ask for referrals and recommendations to ensure that you are only investing in the best places.

Concentrating Solar Power

Solar power is described as the conversion of sunlight into electricity. Sunlight could be changed straight into electricity with the use of PV or photovoltaics. It can also be indirectly converted using CSPs. There are now several devices and structures created which focus and concentrate solar power in various ways depending on the needed use. There are several now several uses of solar power because of the rise of these devices.
On Concentration
Solar power is concentrated in various ways. Solar troughs are the most common and visible. CSPs or concentrating solar power systems make use of mirrors, lenses and track systems to focus on a wide area of sunlight into a small beam. The concentrated heat is used as a source of heat for a conventional power plant. The wide range of concentrating technologies is now available. The parabolic trough is the most developed. Other structures made include the Stirling dish, the linear Fresnel reflector and the solar power tower. Several techniques are used to locate the sun and concentrate light. Working fluid is also heated in all the systems using concentrated sunlight, which is then applied for storing or generating power and energy.
The Parabolic Trough
A parabolic trough is created from of linear reflector that concentrates light right onto a receiver, placed along the focal line of the reflector. The receiver is described as a tube positioned right over the middle of the parabolic mirror and filled with a working fluid. The reflector is created to follow the sun during the daylight hours by tracking right along a lone axis. Parabolic trough systems give the best land-use factor among all solar technologies.
CSP plants use several thin strips of mirror instead of the usual parabolic mirrors to focus sunlight onto a couple of tubes using working fluid. This application provides the advantage that flat mirrors can be used. Flat mirrors are great because these are cheaper and can contain more reflectors within the same amount of space. More available sunlight can then be used. Focusing linear Fresnel reflectors can be used well in compact or large plants.
The Stirling Solar Dish
The Stirling solar dish is also called a dish engine system, which is made of an independent parabolic reflector that tends to concentrate light right onto a receiver placed at the focal point of the reflector. The reflector will track the sun along an axis or two. Parabolic dish systems provide the best efficiency over other technologies. The 50kW Big Dish in Canberra, Australia is a great example. The Stirling solar dish mixes a parabolic focusing dish that includes a Stirling heat engine that regularly drives an electric generator. The benefits of Stirling solar over PV cells are the higher conversion efficiency from sunlight into electricity, plus a longer lifetime.
Power Tower
A solar power tower includes a wide array of heliostats or tracking reflectors that focus light on a central receiver over a tower. Power towers are considered to be the most cost effective and provide better energy storage and higher efficiency compared to other CSP technologies. The solar bowl is described as a dish mirror that is affixed to a certain spot or structure. The receiver will follow the line focus made by the dish.

DIY Solar Power

Before, solar power or solar cell panels are only available in commercial areas and hardware stores. Nowadays, more and more people are trying DIY or do it yourself kits. You can expect to have your own setup in just one day, provided that you have an easy kit to start with. Solar power can be achieved right in your very own home, without the help of a professional. Make sure you follow the instructional guide carefully for the best results.
Building Your Own Solar Power Generator
You can use parts that are available on the internet or your local store. You can create a tiny solar power generator with a budget of only $200 to $300. This is ideal for power failures and life outside the power grid. The setup can also effectively power the modem, television, DC appliances, computer, cameras and lights. You can use this in cabins, archaeological digs, tents and camping trips. This is the ideal setup for people who travel to undeveloped regions and countries.
Initial Steps
First of all, you need to make or buy yourself a tiny solar panel. You can get a device rated at 12 volts or higher for only $100 at a marine supply store or RV store. Next, purchase a battery. Experts recommend that you get rechargeable batteries from available green companies. Get any size of deep cycle 12 volt lead/acid or gel battery. You will need the deep cycle battery for nonstop use. The type in the car is a cranking battery, which is good for starting engines. You may also want to look for bargains and other good deals that will cost only around $50 to $60.
Next Steps
Take a battery box where you will put the generator in. The box may only cost around $10. It is ideal for covering the exposed terminals just in case you have kids inside the house. If you want to install the system in a cabin, pump shed or boat, you can skip this step. Purchase a 12 volt DC meter. This will cost you around $25. Purchase a DC input. The triple inlet model is recommended. You can purchase this for only $10 at a car parts store. The device will be good for powering DC appliances like lights, hair dryers and vacuum cleaners.
If you intend to power AC appliances, you will need an inverter. The inverter converts the stored DC power in the battery right into AC power for majority of household appliances. Measure the watts that you will need. Cheap inverters of various sizes can be purchased online too. Use a drill to attach the meter and DC input to the top region of the box.
Charging
Next, use insulated wire to connect the meter to the wingnut terminals found on the battery. Link the negative pole initially. Only handle a single wire at a time. Link the DC inlet straight to the battery in a similar fashion. Link the solar panel to the battery the same way. Shut the lid using a bungee cord to keep everything tight. Position the solar panel under the sun. It will take 5 to 8 hours to charge dead batteries. You can power different devices like fans, lights and radios.

Get Great Tips About Solar Energy That Are Simple To Use

Oh, the joys of a bright, sunny day! The sun shining on us ought to be used as an energy source. With it, there is a source of power that doesn't pollute our Earth. If solar power appeals to you, keep reading for good ideas and advice from seasoned experts. There are a couple of different photo-voltaic panels to choose from. Less expensive poly-crystalline panels are not as efficient as the costlier mono-crystalline panels. Invest in the best system you can afford.
You don't have to go big to enjoy solar power. Buy some solar-powered lighting to reduce energy usage. You can find them at your local hardware store or mass market retailer. Installing this sort of lighting system is a no-brainer. Walk down your garden path and poke the lights into the ground!
If you perform regular maintenance on your solar power system, it will function well for a long time. Wash it frequently and check it for problems every day. You might want a professional to do this, but you save more if you do it on your own.
You need to find a backup solution you can use if your panels are not producing any power. You can either get a generator or stay connected to the power grid. If you go with the backup generator option, make sure you test its functionality regularly. It's also not a bad idea to have more than one backup generator.
Understand that even if you live in a colder climate, you can still use solar energy. Direct sunlight or specific temperatures are not necessary for solar energy to still be of benefit. Many folks say that their top power days sometimes come on seemingly less than optimal days.
When you want to live in your home forever, invest in solar panels. Installing solar panels requires a substantial investment, so years may pass before the panels generate sufficient savings to cover your cost. You need to make sure your financial situation is stable before you invest in solar energy.
Numerous governmental authorities offer tax credits for solar energy installations. They could offer as much as 30% of the system's cost. Just check some online sources or get in touch with a local agency representative to see if you are eligible.
If you're going to get a house built it's now a good time for you to think about using solar energy. Solar energy is a great alternative energy source since it hardly affects the environment at all. If it hasn't crossed your mind to do so yet, start looking into it.
It's not common knowledge that you don't need a power grid when using solar energy. You can run it all yourself, providing your family with great independence from your town or city. This means there are zero power bills that you need to deal with!
If you wish to get solar panels, start checking the weather. Solar panels that are of high quality are going to create enough energy that can run your home if the panels are in the sun for about five hours a day. Solar energy may not be for you if you live in an area where it is usually cloudy or raining.
If you are a resident of the American southwest, solar power is likely a great idea for you. This area gets a lot of sun, making it the opportune spot for solar energy. If you haven't crunched the number yet, you'd better get started.
You can also start simple with a solar powered water heater so you can see how solar power can help you save money. Your home expends a lot of energy heating your water, sometimes up to 35% of your heating budget. By installing a solar heating system, you can generate returns on your initial investment quickly and more substantially.
Don't walk on solar panels unless you really need to. They can break, and you risk losing a tremendous investment. Keep your weight in the center to reduce the risk of damage if you absolutely must walk on them.
Dry your clothes on a clothes line. This is an old idea that still works today. When it's sunny, hang dry your clothes outside instead of using the dryer. You will save money and still have dry clothes.
Solar panels do more than just provide energy to power your lights. They power appliances, supply heat and air, and they can even warm up the water you use in your home, as well. This ensures that investing in a solar system is going to affect (or get rid of completely!) This is especially true when it comes to your power bills.
