Solar panel. Solar panels absorb the sunlight as a source of energy to generate electricity or heat. A photovoltaic (PV) module is a packaged, connect assembly of typically 6x10 photovoltaic solar cells.
Solar Energy and Its Uses. Utility scale solar energy facilities generate electricity that is sent to energy consumers via electric transmission systems. On a smaller scale, solar energy facilities can be used to generate electricity or hot water for use in individual buildings.olar energy facilities use concentrating solar power (CSP) as the heat source to boil water, or they convert sunlight directly into electricity using solar cells, also known as photovoltaics (PV).
