Plug-in solar included in a broader solar bill. Would exempt certified devices from Eversource and UI interconnection requirements.
If passed: self-install without Eversource or UI approval. At $0.286/kWh, an 800W system could save $315+ per year.
Law not yet enacted. Connecticut utilities currently require interconnection agreements.
Connecticut Residential Renewable Energy Solutions (RRES) program provides tariff-based compensation for solar generation (systems up to 25 kW eligible). Connecticut Green Bank Smart-E Loans offer low-interest financing for solar. Sales tax exemption on solar systems. Property tax exemption for solar equipment. The federal 30% ITC (Section 25D) expired December 31, 2025.

Connecticut has a fully deregulated electricity market. You may be able to get plug-in solar bundled with your electricity plan through a Retail Energy Provider (REP) — potentially at lower cost than buying hardware outright.
