Maine receives about 3.7 peak sun hours per day. The key factor in Maine isn't sun hours — it's the state's high electricity rates (often $0.20-$0.25/kWh). High retail rates plus net metering plus $0-down PPA financing make Maine one of the best solar markets in the country — homeowners can pay 25-35% less per kWh through a PPA than what they're paying their utility.
Maine offers net energy billing (their version of net metering), strong state-level incentives through Efficiency Maine programs, and pairs with Power Purchase Agreement (PPA) financing for $0-down installation. Maine also has some of the highest electricity rates in the lower 48 — which means solar savings are substantial.
Most sites won’t show you a number. Here is what each Maine utility charges all-in — supply plus delivery plus riders, not the supply rate on its own. That is the figure solar has to beat.
| Utility | All-in rate | Detail |
|---|---|---|
| Central Maine Power | ~27¢ | Serves most of southern and central Maine |
| Versant Power | ~27–32¢ | Northern and eastern Maine |
Maine has no state solar rebate and no production incentive — Efficiency Maine does not offer one, and any company claiming otherwise is worth questioning. What Maine does have is 1:1 Net Energy Billing at full retail, against rates 70 to 100 percent above the national average.
Rates as published August 2026, drawn from Maine Public Utilities Commission filings, utility tariffs, ISO New England market data and U.S. Energy Information Administration figures. Utilities reset on their own schedules — check your own bill for the rate on your account.
Net metering rules, interconnection requirements, and rebate availability vary by utility. Our installer network in Maine works with all major providers:
The 30% federal Residential Clean Energy Credit under Section 25D ended for systems purchased after December 31, 2025. If you buy a system with cash or a loan in 2026, you cannot claim it. Any site still advertising a 30% federal credit for a homeowner purchase is running outdated information.
What remains is Section 48E, the commercial investment credit. It applies to third-party-owned systems — leases and power purchase agreements — where the system owner claims it rather than the homeowner. That is precisely what makes $0-down possible.

Maine's harsh winters and coastal exposure put significant stress on roofs. Many Maine homes use metal roofing which pairs well with solar. Solar panels actually help shed snow faster on metal roofs.

For most homeowners in Maine, going solar locks in lower, more predictable power and helps offset rising Maine utility rates. Actual savings depend on your roof, energy usage, and utility — a free, no-obligation estimate shows your specific numbers.
Maine offers net metering, and may offer state incentives or tax exemptions for going solar. Programs and eligibility vary by utility and change over time — consult a licensed tax professional.
