The inverter runs to a smart meter that records the amount of energy you use and also the excess solar energy that is sent back to the utility. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. This flow travels in a circuit of wires that connect groups of solar panels called arrays. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass.

As mentioned above this allows you to store energy generated in the day to use at night reducing the need to use electricity from the grid. A company such as sunrun or. How much energy does a solar panel produce. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
