Solar energy is the cleanest and most available renewable energy source. A solar energy system is an assembly of interacting pieces of equipment designed to collect solar radiation, store the collected energy, and distribute it as needed. A solar energy system works in such a way that roof-mounted solar panel systems absorb and convert the energy-packed photons of natural sunlight into a usable energy form. The main components of a solar energy system are photovoltaic panels, a DC to AC power converter and a rack system that holds the PV panels in place.
