Solar energy is a clean, renewable energy derived from radiant light and heat from the sun that can be harnessed by using different methods or technologies. It can be used for several purposes, such as generating electricity; heating or cooling spaces in buildings; and heating water for
home, commercial, or industrial uses.
Two of the main solar energy technologies are photovoltaics (PV) and concentrating solar power (CSP). PV converts sunlight directly into electricity by using panels. Once the sunlight hits the solar panels, photons from the sunlight are absorbed by the cells in the panels, generating an electric field through the layers, causing electricity to flow.
