The short answer:
In some states, if you generate more power than you use, your utility company will pay YOU. This is called "net-metering".
The long answer:
Here are 5 important things to know about net metering.
1: Your utility company will pay you.
- Sound too good to be true? It's not.
- When your solar installation is installed, you'll get a special two-way electric meter that monitors electricity produced versus consumed.
- If your solar installation produces more electricity than you use, the excess electricity is exported to the grid.
2: There is a limit to how large your system can be.
- Most states have a cap on the size of a solar installation they will compensate excess electricity for
- For example, in New York State, residential systems are limited to 25 kW (kilowatts) per electric meter.
- Don't worry, the average home solar system is 5-10kW.
3: How much you get paid depends on where you live.
- You will be credited for your excess electricity sent to the grid by your utility company on a per kilowatt-hour (kWh) basis.
- The price per kWh varies depending on a variety of things - what state you live in, the local policies, what type of install (residential, commercial, etc).
- Most commonly, you are credited with the "retail rate" you pay for electricity or a bit less.
- In certain cases, compensation levels may be zero ... see point #4.
4: Net-metering laws wildly vary state by state...and they keep changing!
- Almost every state has some form of solar net metering laws as of 2021 - yay!
- BUT the laws & level of compensation vary depending on what state you live in.
- Be sure to discuss if net metering is in effect where you live with your solar provider.
5: Good for you & good for the grid.
- Net metering allows you to make money back from your solar installation faster. Woohoo!
- It also allows your to essentially be a mini 'power plant' for your neighbors and provide local power.
- Local power generation helps smooth electricity demand across the grid and prevent grid failures.
More power to the people.
