Connecticut homeowners across 96 towns are served by 8 electric utilities, with residential rates ranging from 13.2¢ to 36.0¢ per kWh. Pairing rooftop solar with battery storage maximizes self-consumption and provides backup power during outages — Connecticut homes experience an average of 12 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 CT Energy Storage offers up to $7,500 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.
Connecticut participates in demand response programs that pay battery owners for peak shaving. At $225/kW/year, a typical 5kW battery earns approximately $1,125/year in passive income, significantly improving the economics of battery storage.
