FAQ

Can I claim the federal credit if I lease my solar panels?

No. The Clean Energy Credit applies only to the system owner. With a lease or PPA, the third-party owner claims it.

How does net metering work under NEM 3.0?

You earn export credits based on time-of-use rates. Credits roll over monthly and can be settled annually; export values vary by hour/season. Calculate your potential export credits.

Do incentives change during the year?

Yes. Local rebates open/close and funding caps can be hit quickly. That's why monitoring programs regularly is important.
