Is balcony solar legal in Connecticut?

Short answer: Yes. Connecticut's law took effect October 1, 2026. It allows one plug-in kit per electric meter, up to 1,200 W, with no utility approval or fee.

What the law says

• Public Act 26-127 (HB 5340), signed June 4, 2026. Its plug-in section took effect October 1, 2026.
• Up to 1,200 W, and only one device per electric meter.
• Your utility can't require its approval, a fee, or extra equipment. A qualifying kit is exempt from interconnection agreements.
• The kit must be certified by UL or an equivalent lab and meet UL 1741, the State Building Code, the National Electrical Code, and IEEE 1547.
• No notice to the utility is required.

One catch: the warning the law requires on every kit says excess power is "charged to the customer as usage unless such customer utilizes an electric meter that allows for net metering." If your kit makes more than your home is using, check what your meter does with it.

Renters and HOAs

• The law says nothing about landlords or HOAs. Building codes, fire codes, and local ordinances still apply.
