What is Net Metering?
Net energy metering (NEM) is a billing arrangement in which excess electricity production from photovoltaic (PV) solar panels is tracked by your electricity provider and subtracted from your monthly electric utility bill.
When a solar system produces more kilowatt-hours of electricity than the home is consuming, the excess generation is fed back into the grid.
How Does Net Metering Work?

Benefits of Net Metering
Save on Utility Bills
Concerned about high utility bills? Net metering reduces them by letting solar panels power your home. Without net metering, your solar system can only offset immediate power usage when the panels generate electricity.
Energy Independence
With net metering, you become less reliant on the grid for electricity. You can use your stored energy credits during the evenings or on cloudy days, enhancing your energy self-sufficiency.
Environmental Impact
By using your excess solar energy and reducing reliance on conventional grid electricity, you contribute to a greener, more sustainable future by lowering your carbon footprint and reducing greenhouse gas emissions.
Community and Grid Benefits
Net metering can reduce the strain on the electrical grid during peak demand, leading to a more stable and reliable energy supply for everyone in your community.
In summary, net metering is a win-win for solar customers, providing cost savings, energy independence, environmental benefits, long-term financial gains, and a brighter, more sustainable future.
