Maine homeowners across 91 towns are served by 7 electric utilities, with residential rates ranging from 11.6¢ to 32.0¢ per kWh. Pairing rooftop solar with battery storage maximizes self-consumption and provides backup power during outages — Maine homes experience an average of 18 outage hours per year.
A typical solar+battery system combines an 8kW solar array ($24,000-$30,000) with a 10-13.5 kWh battery ($12,000-$18,000). The Efficiency Maine offers up to $4,000 toward the battery, and many utilities add their own solar and battery rebates. The federal residential ITC (Section 25D) expired December 31, 2025, so state and utility programs are now the primary incentives for homeowner purchases.
