Law in effectLaw in effect

The key facts

Bill or law
HB 5340, Public Act 26-127
Size limit
1,200 watts; one device behind the applicable customer meter
Signed
2026-06-04
Effective date / scope
2026-10-01

Qualifying certified plug-in solar devices are limited to 1,200 watts and one device behind the applicable customer meter. The utility exemption removes prior approval, interconnection agreements, and added device-related fees for qualifying devices.

The exemption does not displace safety, building, electrical, or local code obligations. May 20, 2026 was the public-act designation date, not the governor's signing date.

Installation checklist for Connecticut

  • Use a qualifying certified device of no more than 1,200 watts, with only one device behind the applicable meter.
  • Confirm the circuit, mounting, local code, and landlord or HOA requirements; follow the certified system's instructions.

Before you buy in Connecticut

This page is informational research, not legal advice — and it can fall out of date quickly. Before installing anything, confirm the current law and its start date, any size limit, your local building and fire codes, your utility’s requirements, that the kit is certified as a complete system, your landlord or homeowners association (HOA) rules, a safe way to mount it, and the maker’s instructions.

Estimate your savings in Connecticut

Use the calculator to get a rough idea. For a truer number, swap the national average electricity price for your own rate (it’s on your bill), and remember that surplus power you send back may earn nothing unless your state and utility specifically pay for it.

A planning estimate, not a promise. It doesn’t check whether plug-in solar is legal where you live, whether a kit is certified, whether your outlet or mount is suitable, or whether your utility pays for surplus power.
