Connecticut plug-in solar status

Passed but not yet effectiveSigned; effective October 1, 2026
Where Connecticut stands: Connecticut's omnibus solar law, HB 5340 (Public Act 26-127), was signed by Governor Ned Lamont on May 20, 2026. Its plug-in solar provisions take effect October 1, 2026.

The key facts

Bill or law
HB 5340
Size limit
1200 watts
Takes effect
2026-10-01

The law allows one plug-in solar device per household at up to 1,200 watts, with no utility approval, interconnection agreement, or added fees required.

Because the plug-in rules take effect October 1, 2026, wait for that date — and for certified products — before relying on the law.

Confirm your local codes and any landlord or homeowners association (HOA) rules before installing.

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This page is informational research, not legal advice — and it can fall out of date quickly.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.
