Featured Snippet Summary
Net energy metering (NEM) is a utility billing system that credits you for the excess electricity your solar panels export to the grid. In 1-to-1 retail states, you receive full credit for every kWh sent, which offsets your future energy imports.
Net metering is critical for residential solar panel installations because it allows you to utilize the utility grid as a virtual battery. When your solar array overproduces during sunny mid-afternoon hours, the excess energy is automatically sent to the grid, spinning your electric meter backward.
Net Metering Billing Types
- 1-to-1 Retail Credit: The gold standard. You receive the exact same rate for solar exports as you pay for grid imports.
- Net Billing (NEM 3.0): Export credits are reduced by about 75%. This requires adding battery storage to store and use your own power.
- Avoided Cost: The utility pays you a very low rate (usually 2 to 4 cents per kWh) for exports, making solar less attractive without a battery.
