See how much money solar could save you at your address. No sales
pitch, no calls. If the math doesn't work, we'll say so.
And if it does, we'll soon be able to vet a single
installer for you — only if you ask, and only with your consent each step.
Locating the building…
SIA designs the best possible system for your address in under 60 seconds
— free. Use it to compare against a quote you've already received.
Built on Google Solar imagery and PVWatts® modeling, the same data
installers use. Works for most US urban and suburban addresses. Nothing is saved
without your consent.
Your system is designedPanels placed and sized for the best return on this roof.
See what it saves, or adjust anything first.

Your solar snapshot
Ways to pay — and what each could save you
Estimated with standard assumptions for this location and system.
These four financing paths are the same ones full members can fine-tune input by input.
Crunching the numbers…
Informational estimate, not an installation quote. “25-yr savings”
is cumulative and net of what you pay (purchase, loan, lease, or PPA). Battery storage is not
included in this snapshot. See the
full methodology.
Get your full analysis — free
Adjust every assumption, add battery storage, compare net-metering and time-of-use
scenarios, see hourly production & battery dispatch, audit the lease/PPA fund math,
and export a complete proposal. Create a free account and it's all yours — plus up to
3 saved projects you can reopen on any device.
No phone number, and nobody contacts you. Installer
matching is coming later, and only ever happens if you explicitly ask for it.
