Photovoltaic Systems (PV systems) – These are panels made from materials that, when exposed to sunlight, use heat and light to shake electrons loose and create an electric current in a process called the photovoltaic effect.
Solar Water Heating – Solar collectors are usually rectangular chambers with multiple small tubes called flat-plate collectors, which circulate water or another fluid
Solar Thermal Electricity – Solar energy can be concentrated to heat water and run turbines to produce clean-electricity.
Solar Heating and Cooling – For offices and larger buildings, solar energy can be more efficiently harnessed, as compared to houses and smaller premises. On a larger scale, even parabolic-trough collectors can be used for space heating and solar water heating in place of traditional methods.
