Electricity from Sunlight
Photovoltaic solar energy systems use sunlight to generate electricity. It lowers your utility bill, and helps reduce fossil-fuel consumption and global warming. A system lasts for many years, and adds to the value... of your home.
How it works •Sunlight hitting silicon cells in a module generates a direct current.
•A switch protects the solar modules from grid power fluctuations.
•The solar direct current goes from the solar modules to an inverter.
•If there is extra solar current, the system feeds it to the utility grid, running the meter backwards.
•If more power is needed, the switch draws power from the utility grid.
