Every number shows its source. Click any figure in your report and you'll see exactly where it came from — and anything we can't compute honestly, we mark as unknown instead of guessing.

    Your address We match it and pull the solar resource for your exact location.

    Ten questions Your bill, your heating fuel, your roof. Two minutes.
  3. 3
    Your ranked plan Upgrades ordered by what they actually return for your house.

2026 changed the math

The 30% federal tax credit for homeowner-purchased solar (§25D) ended December 31, 2025. Any quote that still includes it is wrong. Our reports reflect current law — and show you which local programs remain where you live.
