Commercial solar in Connecticut (2026)

In Connecticut, the average commercial electricity rate is about 23.76¢/kWh — above the U.S. average of roughly 17.6¢. Because a solar system's payback is driven mostly by the utility rate it offsets, Connecticut's high rates make business solar a strong bet in 2026.

Connecticut still offers full retail-rate net metering, so every kWh you export is credited at the same price you pay. That is the most favorable arrangement for solar economics and shortens payback.

Businesses use the Section 48E commercial credit (≈30%, up to ~50% with adders) plus first-year bonus depreciation — together typically recovering ~45–55% of project cost. Construction-start timing matters; verify before acting.

For a typical Connecticut business spending about $1,500/month on electricity, our model estimates a 54.11 kW system costing roughly $78,472 after incentives, paying back in about 4.4 years, with on the order of $371,507 in 25-year savings. These are estimates built from Connecticut's real electricity rate — get a quote to confirm your numbers.

Businesses in Connecticut should weigh construction-start timing for the commercial credit and confirm whether the project qualifies for the domestic-content or energy-community adders, which can lift the credit toward 50%.
