Solar energy converters

What are some energy conversions that begin with solar energy?

Solar photons convert naturally into three forms of energy—electricity, chemical fuel, and heat—that link seamlessly with existing energy chains. Despite the enormous energy flux supplied by the Sun, the three conversion routes supply only a tiny fraction of our current and future energy needs.

How do you convert solar energy into electricity?

Solar-powered photovoltaic (PV) panels convert the sun’s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.

What is solar energy conservation?

While solar power is a source of energy that is renewable, it is not a method of energy conservation. Instead, it is a method of reducing our dependence on fossil fuels.
