How Solar Works

Photovoltaic Modules or “Solar Modules”

Photovoltaic modules are mounted on your roof or grounds. These modules convert sunlight into DC electricity.

Inverter

DC electricity generated by the solar modules is sent to the inverter. The inverter converts this DC electricity to AC electricity, which is identical to the AC electricity you purchase from your electric utility provider.

Main Fuse box or “Electric Service Panel” or “Breaker Box”

AC electricity from the inverter flows to your main fuse box. This electricity will now power your electrical loads in your house.

Meter

Any excess power you generate will flow through the meter back to the utility grid. Your meter will go backwards indicating you are supplying electricity to the grid and getting credit for the power you produce.

Utility Grid

The utility grid is the interconnection network between power companies and electricity users on the grid. When you are not generating power, you will receive power from the utility grid. When you generate more power than you use, you supply power to the utility grid allowing others to use this power of which you are credited.

Net Metering

Net metering legislation guarantees your right to get credit for electricity you supply to the grid. You are credited at the same rate you would have paid for this electricity. Customers with Time-of–Use electricity suppliers will be credited at peak rate prices during peak hours of electricity usage. Fortunately, this more or less corresponds to peak sun hours too!
