Connecticut plug-in solar status
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This page is informational research, not legal advice — and it can fall out of date quickly.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.
