Solar power generates electricity by using either solar thermal systems that convert sunlight into heat to produce steam that drives a generator, or photovoltaic systems, which transform sunlight into electricity through the photovoltaic effect. This energy can be used to generate electricity or be stored in batteries or thermal storage. Solar Panels: Solar panels are. . Solar power works by converting energy from the sun into power. Solar power on Earth begins about 93 million miles away. Way out in space there's a gargantuan ball made up of gas, mostly helium and hydrogen.
