Independent, verified estimates of your real year-round output — right-sized systems, optimal panel alignment, and a second opinion on any installer's quote. For homes and small businesses.
No panels to sell. Just the numbers, simulated from your address.
Installers and solar salespeople earn more when they sell you more — so their estimate is a sales tool, not a neutral forecast. And it's the number you're about to sign for. Watt If runs the math independently, with nothing to sell, so you find out what your roof will actually do before you commit.
Send your address and any quote or proposed system you've been handed. Five minutes, one form.
We model your building's real month-by-month output from local weather, roof geometry, and shading.
A clear, independent report: true yearly output, the right system size, and optimal panel alignment.
Month-by-month production simulated for your exact location, not a national average.
Matched to your roof and your actual energy use — no oversizing to pad the invoice.
The tilt and orientation that squeeze the most kilowatt-hours out of your space.
We check the numbers you've been given and tell you where they hold up — or don't.
Going solar is one of the biggest purchases you'll make for your home. Know exactly what you'll get back — and whether the quote on your kitchen table is honest — before you sign.
More panels means more room for an expensive mistake. We size the system to your real load and operating hours, so the investment pays back on schedule.
Flat fees. No commission, no upsell — that's the whole point.
An independent simulation of your current or proposed system — your real month-by-month output, so you can see what it will actually produce and check any quote you've been given.
Everything in Verify, plus our recommendations to get more from your roof — the right system size and the optimal panel alignment for your location.
