By Jessica Martinez · Updated June 20266 kW system cost and incentives for Maine homeowners.
By Jessica Martinez · Updated June 2026A 6 kW home solar system in Maine runs about $19,440 before incentives. For Maine homeowners, the 30% federal tax credit brings that to roughly $13,608 out of pocket, a difference of about $5,832.
Maine's sun hours run below the national average, so more panels are needed for the same output. The solar cost calculator narrows that down to your actual Maine home.
| System size | 6 kW |
|---|---|
| Price before incentives | $19,440 |
| 30% federal tax credit | -$5,832 |
| Price after credit | $13,608 |
Central Maine Power and Versant both offer net metering programs.
Installer competition and local permitting rules both move the final Maine price. Use the system size calculator to match panel count to your actual Maine usage rather than a flat 6 kW.
