How Solar Works

A Grid Tied Photovoltaic (PV) Solar Electric System

	Sunlight is absorbed into the cells of the solar panels. The electrons within the silicon layers of the photovoltaic cells become excited and produce DC electricity.
	The new electricity passes through an inverter, which turns it into the same type of AC power that’s delivered by the utility company.
	Your new solar electricity first powers any lights, appliances, or equipment you happen to be using in the building. This free electricity first supplies your needs. Then, any remaining power flows onto the grid.
	Excess electricity flows through your electric meter out to the public power grid. A “net meter” spins both forward and backward depending whether you’re producing excess power or taking it from the utility company.
	You only pay for “net usage” – the difference between the amount you take from the utility company and the amount you give back. Depending on the size of your system and usage, the electricity you produce will cover either all or part of your overall electric bill.

This is a “grid tied” system which means that you are connected to the grid as both a producer and a user.

Quality photovoltaic modules withstand cold, heat, rain, and snow. Snow slides off of the non-stick surface. Panels are mounted in direct sunlight.
