Solar powerÿis the conversion ofÿsunlightÿintoÿelectricity, either directly usingÿphotovoltaicsÿ(PV), or indirectly usingÿconcentrated solar powerÿ(CSP). Concentrated solar power systems useÿlensesÿorÿmirrorsÿand tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into anelectric currentÿusing theÿphotovoltaic effect.[1]
