How long does it take for solar panels to pay for themselves?

In most U.S. states, residential solar panels pay for themselves within 6 to 10 years, depending on local electricity rates, solar irradiance, state rebates, and net metering compensation rules.

How does net metering affect solar savings in 2026?

Net metering credits homeowners for excess solar electricity sent back to the grid. Traditional 1:1 net metering offers the fastest payback, while Net Billing (like California NEM 3.0) credits at wholesale rates, making solar battery storage essential.

How do I calculate solar panel savings by ZIP code?

Enter your ZIP code into PVFig to combine NREL PVWatts solar radiation data with your utility electric tariff. This computes expected monthly kWh generation and offset value.
