Solar energy is one of the cleanest and most viable forms of renewable energy in the world. Each day, the sun generates more energy than the world uses, most of which is untapped. Unlike fossil fuels this abundant renewable source creates energy without any producing emissions or harmful greenhouse gasses. We at Novus agree with the experts who believe that energy generated directly from the sun will play an increasing larger role in our bright future.
How Solar Works
Photovoltaic (PV) cells are used to convert sunlight into electricity. The PV cell consists of two slices of silicon, one positive and one negative, placed under a thin layer of glass. As the sunlight’s photons hit the PV cell they knock electrons off of the silicon slice, allowing them to flow freely. Between the positive slice and the negative slice of silicon, there is an electric field that forces the electrons to flow in one direction. This flow of electrons forms a direct current (“DC”), which can then be drawn externally, by placing wires at the top and at the bottom of the PV cell. From there the DC current is run through a transformer which converts the DC current to an alternating current (“AC”), thus allowing this electricity to be integrated into our electrical grid.
