Connecticut tucked plug-in solar into a big energy bill, HB 5340. Governor Lamont signed it on June 4, 2026. The plug-in rules started October 1, 2026. This guide is as of October 2026. It is not legal advice, so check your utility's page before you buy.
Is balcony solar legal in Connecticut now?
Yes. The plug-in sections of Public Act 26-127 took effect on October 1, 2026. The law calls these "portable solar generation devices." They are exempt from the utility's interconnection agreement rules. Local building and fire codes still apply. For other states, see which states allow balcony solar.
How many watts can I plug in in Connecticut?
Up to 1,200 watts of maximum output, and only one device per customer meter. It must plug into a standard 120-volt outlet on your side of the meter. It cannot be permanently fixed in place. It also needs an anti-islanding feature, so it does not power the grid during an outage.
Do I need to tell my utility in Connecticut?
No. The law has no notice rule. A utility cannot ask for approval first. It cannot charge a fee, except charges you run up by using the device. It cannot demand extra controls or equipment. The utility is not liable if the device causes damage. We found no utility guidance yet, so check your utility's page.
Can my landlord or HOA say no to balcony solar in Connecticut?
The law does not stop them. It has no rules for landlords, renters or HOAs. Your lease and HOA rules still count. If you rent, ask in writing first. Our renters guide has a checklist. Local fire and building rules also apply to where and how you set it up.
Do I get paid for power I send to the grid in Connecticut?
No, and it could cost you. The law makes the device carry a warning. Extra power can be charged to you as usage unless you have a meter that allows net metering. So pick a setup that uses what it makes, or check your meter first. Our savings guide shows how to estimate use.
What does a balcony solar kit need in Connecticut?
It must be certified by UL or an equivalent national testing lab, and it must meet UL 1741. That is the standard the statute names. It must also meet the national electrical code and the state building code. The law does not name UL 3700. See kits sold in the US.
What can I do in Connecticut today?
Check your meter type first. Then check your sun and your outlet. Read what balcony solar is. Look for a kit that meets UL 1741 and has the required warning. Aim to use the power as it is made. Renters should get written permission before hanging anything.
