How Solar Systems Work
The solar panels on your roof harness energy from the sun.
The inverter converts that energy into electricity to be used in your home
Your solar panels continue to power appliances in your home while the sun is shining
Electricity you don’t use from your solar panels will be sent to the grid where you will receive a credit as compensation
