Solar + Heat Pump in Maine

Maine homeowners across 91 towns are served by 7 electric utilities, with residential rates ranging from 11.6¢ to 32.0¢ per kWh. Combining rooftop solar with a cold-climate heat pump eliminates both your electric bill and fossil fuel heating costs — the two largest energy expenses for Maine households.

Most Maine homes currently heat with Oil & Propane, spending approximately $2,900/year. A cold-climate heat pump reduces heating costs to approximately $820/year in electricity, saving $2,080/year on heating alone. When you power the heat pump with rooftop solar, the marginal electricity cost drops to near zero. Cold to very cold winters with design temps of -5°F to -15°F. Cold-climate heat pumps essential.

The Efficiency Maine offers up to $3,000 for heat pump installation, and many utilities add their own solar and heat pump rebates. The federal residential ITC (Section 25D) expired December 31, 2025, so state and utility programs are now the primary incentives for homeowner purchases.
