Did you know scientists estimate that more than enough solar energy strikes the Earth every hour to power the whole world for a whole year? Yes, really.
Solar power technology changes the energy of the sun’s rays into electricity or heat we can use. There are many different types of solar energy technologies – including photovoltaic (PV), concentrated, passive, and thermal – but at the end of the day, each is about harnessing the sun’s virtually inexhaustible energy to power our lives.
Photovoltaic solar (PV) is the best known the most widely recognized (and what this e-book will focus on most).
