Net metering is a utility billing arrangement that accounts for eligible electricity a solar system sends to the grid. The value and treatment of exports depend on state rules, utility tariffs, system eligibility and timing. It is not identical in every market.
A meter records grid interaction
The home can import electricity when it needs more than solar produces and export electricity when production exceeds on-site use. The utility statement applies its approved rules to those measurements.
Credits may not equal the full retail rate
Export valuation, rollover, expiration and settlement vary. Some programs use retail-style credits; others use different rates or structures. Always check the current utility program.
Program rules can change
Eligibility can depend on application date, system size and utility territory. A proposal should identify which current rule it assumes and avoid guaranteeing future policy.
