Use of estimates

All figures on SunWorth are modeled estimates derived from NREL PVWatts v8 and NREL/EIA rate data. They are provided "as is" for general information, are not a quote, and should not be relied on as financial, tax or engineering advice. Always confirm pricing and incentives with a licensed installer.

Affiliate disclosure

When you request quotes or buy through our links, we may earn a commission or referral fee at no extra cost to you. This never changes your estimate or the order in which results are shown.

No affiliation

SunWorth is an independent project and is not affiliated with, endorsed by, or sponsored by NREL, the U.S. Department of Energy, the EIA, or any government agency.
