While the absorption of the light into the cell is enough to free electrons, the cells also contain an electric field that can steer the electrons where they need to go. In essence, this flow is actually a current. As light enters the cells, the semi-conductor pulls the energy in the form of electrons from it and allows them toįlow through the material.

The cells must be made of a material like silicon or a similar single cell semi-conducting material. These cells are where the conversion from light to electricity takes place. So how does a seemingly simple looking panel harness sunlight and transform it into electricity? Solar panels contain photovoltaic cells. How do these panels convert sunlight into energy that homeowners can use to power their appliances and their homes, a practice that ultimately protects the environment and leads to cheaper utility bills and economic freedom? Yet too most people, how solar actually works is a mystery. From astounding new solar products like AC coupled backup systems and high efficient microinverters to banks of solar panels that provide electricity to run our homes and, eventually, even our cities, the solar revolution may well have begun in earnest. The era of solar energy, as many would say, is upon us. In fact, many people wouldn't call it a trend at all, merely a return to the practical know-how of yesteryear when people simply had to do it themselves and took great pride in their handiwork! Yet few DIY projects are as cost-saving and investment-rich as the installation of a solar system. The do-it-yourself (DIY) craze is hardly crazy when one considers the mind-boggling cost savings resulting from this trend nationwide.
