System size
A recommended kilowatt range based on estimated electricity usage and local production.
Solar numbers without the sales pitch
Know what solar could cost before you call an installer.

Free preliminary estimate
What could solar cost for your home?
One estimate, explained
The five numbers that make solar easier to evaluate
Gross cost
A low-to-high installation range instead of a suspiciously precise teaser price.
Incentive reality
No phantom 30% federal credit — it ended for 2026 installs. We say so, and point to real state programs.
Annual savings
An estimate based on electricity displaced and conservative export value.
Payback
A range showing how long estimated savings could take to cover net cost.
Assumptions
The rates, production, panel wattage and other inputs behind every result.
Built for clarity
A useful estimate should show its work.
Solar economics depend on location, utility rates, roof conditions, equipment and incentives. We surface those assumptions so you know where the estimate is strong—and where a site visit is still necessary.
