It’s important to understand how solar works. Solar panels are mounted on your roof for optimal sun exposure, preferably facing South or West. Sunlight is converted into DC power through solar modules.
The inverter converts DC power produced from the solar modules, into the AC power used in your house or business.
The net-meter measures the amount of electricity provided to you by your local utility. When your solar modules produce more electricity than you are using, it goes back to the utility company’s grid, crediting your account (your meter literally spins backwards!)
Your electric company provides electricity automatically “on demand.” When the sun is out, excess solar production provides you with an energy offset credit. During the night, power is readily available from the grid.
