What is solar?

More energy from the sun falls on the earth in an hour than is used by everyone in the world for a year. A variety of technologies convert sunlight to usable energy for buildings. The most commonly used solar technologies for homes and businesses are photovoltaics (PVs) for electricity.

Solar power is energy from the sun that is changed over into thermal or electrical energy. Solar energy is the cleanest and most plentiful sustainable power source accessible, and the U.S. has the absolute most abundant solar resources on the planet. Solar technologies can leverage this energy for many uses, including producing power, producing light or a comfortable interior environment, and hot water for domestic, business, or industrial usage.
