2. Solar panel - Wikipedia

   en.wikipedia.org/wiki/Solar_panel

   Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light.

3. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

4. Photovoltaic mounting system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_mounting_system

   PV panels mounted on roof Workers install residential rooftop solar panels. The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle.

5. Applications of photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Applications_of_photovoltaics

   The largest solar power system flown in space is the electrical system of the International Space Station. To increase the power generated per kilogram, typical spacecraft solar panels use high-cost, high-efficiency, and close-packed rectangular multi-junction solar cells made of gallium arsenide (GaAs) and other semiconductor materials.

6. Solar power - Wikipedia

   en.wikipedia.org/wiki/Solar_power

   Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current . [ 2 ]
