Maine Community Solar Program

The Maine Community Solar Program is a net metering tracked in the federal DSIRE database as one of Maine's solar policy levers. Eligibility is scoped to residential customers, with a stated benefit of Bill credits for subscribers. The program does not carry a scheduled sunset in DSIRE, though appropriations and enabling legislation can still be revised year to year. Like every state-level incentive, it is designed to stack on top of the federal 30% Investment Tax Credit rather than replace it.

Layered onto Maine's underlying economics, this matters more than it might look in isolation. The state averages 4.3 kWh/m²/day of usable sunlight and residential rates of 26¢/kWh, producing an estimated 7,534 kWh/year and $1,959 in annual utility offset on a typical 6kW system costing $18,300. Without incentives that baseline already implies a 9.3-year simple payback — every dollar this net metering delivers compresses that payback further and improves 25-year net returns, currently modeled at roughly $30,675 before accounting for the Maine Community Solar Program itself.

This program is not the only option. Maine has 3 solar incentive programs indexed in DSIRE, including adjacent options like ME Solar Energy Property Tax Exemption. The state's net metering policy is classified as full, which governs how excess generation is credited and often determines whether a given program is worth claiming for a specific household. Before applying, verify current terms on the official program page, confirm your utility participates, and consult a qualified tax professional about how state credits interact with the federal ITC on your return.
