What is solar energy?
The sun is an incredible and renewable resource that has the power to fuel life on earth and provide clean, sustainable energy to all of its inhabitants.  In fact, more energy from the sun reaches our planet in one hour than is used by the entire population of the world in one year.  The sun’s energy can be converted into electricity through solar photovoltaic (PV) modules (photo = light, voltaic = electricity).
