Solar power

Solar power

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.

Solar power

Dopant

Energy; Solar power

A chemical element (impurity) added in small amounts to an otherwise pure semiconductor material to modify the electrical properties of the material. An n-dopant introduces more electrons. A p-dopant ...

Electric circuit

Energy; Solar power

The path followed by electrons from a power source (generator or battery), through an electrical system, and returning to the source.

System operating voltage

Energy; Solar power

The photovoltaic array output voltage under load. The system operating voltage is dependent on the load or batteries connected to the output terminals.
