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.
