After watching my neighbor overpay $8,000 because his installer "forgot" to mention the state rebate deadline, I started documenting every incentive program in America. State credits, utility rebates, net metering rules that change by zip code — the solar industry profits from this confusion. I don't.

I built this because every "free solar calculator" online wants your phone number so a salesperson can call you 47 times. This one doesn't. Enter your numbers, get your estimate, leave. That's it.
Methodology: EnergySage cost/watt data · NREL irradiance · EIA electricity rates
