Home Solor Panels
Solar panels (photovoltaic panels) for the use of renewable energy from the sun, and are a clean and pleasant environment to collect solar energy. Here, the solar panel information, we have accumulated a wealth of information on solar panels and photovoltaic technology field. You can learn how the solar panels, how they are made, where to get them and how to configure.
The solar panels using light energy (photons) to produce electricity from solar photovoltaic effect. structural element (load), the module can be either a surface layer or back layer. Most modules use wafer-based crystalline silicon cells or cells based on cadmium telluride or silicon. Lead wires, which take away from the current disks can contain silver, copper or other conductors (but usually non-magnetic) transition metal.
The cells must be electrically connected to each other and the rest of the system. The cells must also be protected against mechanical damage and moisture. Most solar panels are rigid, semi-flexible, but they are available, based on thin film cells. Electrical connections are made in series to achieve a desired output voltage and / or in parallel to provide a desired amount of the capacity of the power supply.
separate diodes may be needed to reverse the flow in the event of partial or full shade, and at night. pn junctions of mono-crystalline silicon cells can be enough to reverse the current features are not necessary. Reversing the flow of waste control and can also lead to overheating of the shaded cells. Solar cells become less efficient at higher temperatures and the installers try to provide good ventilation behind the solar panels.
Some recent solar panel is also planning to hub, where the light is focused by lenses or mirrors on a series of small cells. This allows the use of cells, the high cost per unit area (eg gallium arsenide) and economic criteria.

Solor Power Systems
Solar energy is the conversion of sunlight into electricity, either directly through photovoltaic (PV), or indirectly, by using solar thermal (CSP). Solar thermal systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small bar. Photovoltaics convert light into electrical current through the photoelectric effect.
Concentrated photovoltaics (CPV) systems use sunlight concentrated on surfaces for photovoltaic electricity generation. Solar concentrators of all varieties can be used and are often mounted on a solar tracker to keep the center of the cell as the sun moves across the sky. Luminescent solar concentrators (in combination with a solar cell PV) can also be considered a CPV system. Luminescent solar concentrators are useful because they can improve the performance of photovoltaic solar panels dramatically.
Space-based solar power is a theoretical project to collect solar energy in space for use on Earth. SBSP is different from the usual way of collecting solar energy and solar panels to collect energy must reside in the satellite in orbit, often referred to as solar power satellite (SPS), and the surface of the earth. Space, a collection of solar energy does not affect the day / night cycle, weather, seasons, or the effects of filtering of atmospheric gases on Earth. The average solar energy per unit area outside the Earth's atmosphere is available in the order of ten times the Earth's surface. However, there is no shortage of energy reaches the surface. Amount of solar energy reaches the planet's surface each year, about twice the amount of energy that will forever change the coal, oil, natural gas and uranium mined combined with breeder reactors.
