Solar Panels in Maine are gaining ground, even though the state is better known for long winters than sunny skies. Surprisingly, Maine still averages 190 sunny days per year, and with electricity costs among the highest in New England, solar panels are a smart long-term investment.
Cost of solar panels in Maine
Residential systems typically cost $13,000 to $23,000 before incentives. Price per watt runs $2.6–3.0, a bit higher than the national average. Most homes use 600–900 kWh monthly, requiring a 5–7 kW system.
Incentives and programs
Maine supports solar adoption through:
- Federal Solar Tax Credit (30%).
- Net energy billing credits from utilities, compensating excess solar generation.
- Property tax exemption for added solar value.

Net metering in Maine
Maine offers net energy billing, which works similarly to net metering. Credits are applied for every kWh exported, rolling over month to month. This makes solar profitable despite seasonal variability.
Payback and ROI
High electricity rates (averaging $0.26 per kWh in 2025) allow solar systems to pay back in 8–11 years. Lifetime savings often exceed $25,000–$35,000.
FAQ
How much do Aptos panels cost in Maine? Around $2.8 per watt.
Is Maine good for solar? Yes — high electricity costs offset fewer sunny days.
Are there rebates? Primarily federal ITC and utility billing credits.
Do Aptos panels work in snow? Yes, they’re designed to handle northern winters.
Conclusion
Maine homeowners can take advantage of high electricity rates and net energy billing to maximize solar savings. Aptos panels ensure long-term durability in the state’s cold climate.
