Principle of solar energy
The grid -tied solar system is an electricity generating solar PV power system that is connected to the utility(State) grid. It consists of solar panels, one or several on grid inverters, Wifi Monitor Device, Mounting Brackets and grid connection equipments.
Users can feed excess power to the grid where it is consumed by other users. The feedback is done through a meter to monitor power transferred to AC loads single phase(110/120V;220/230/240Vac) or three phase(240V;380V;480Vac).  If photovoltaic wattage substantially exceeds average consumption, the energy produced by the panels will be much in excess of the demand. In this case, the excess power can yield revenue by selling it to the grid with local feedback policy.
