Portable Solar Panels Now Legal — HB 5340 makes plug-in solar up to 1,200 watts explicitly legal in Connecticut. Learn how renters, apartment dwellers, and homeowners can use portable solar.
Update May 2026: Connecticut House Bill 5340 (HB 5340) was signed into law, making plug-in solar panels up to 1,200 watts explicitly legal without requiring utility approval. This is a game-changer for Connecticut residents who want clean energy but can't install traditional rooftop solar.
Plug-in solar panels (also called portable solar, balcony solar, or plug-and-play solar) are self-contained solar generating units that generate electricity and feed it directly into your home's electrical system through a standard outdoor outlet.
Connecticut House Bill 5340, signed into law in May 2026, includes these key provisions:
If you're renting — whether an apartment, condo, or house — traditional rooftop solar isn't an option. Plug-in solar gives you a way to generate your own clean electricity without your landlord's permission or permanent modifications.
Living in an apartment or condominium often means no roof access. Plug-in solar panels can be placed on balconies, patios, or near windows to generate power for your individual unit.
Even if you have rooftop solar, plug-in panels can add extra generation capacity — charging an EV, running a home office, or offsetting seasonal energy use.
Portable solar moves with you. No need to leave behind your solar investment when you relocate.
A 1,200-watt plug-in solar system in Connecticut can produce approximately:
| Feature | Plug-In Solar | Traditional Rooftop Solar |
|---|---|---|
| System Size Limit | 1,200 watts | Unlimited (based on roof space) |
| Installation | DIY or professional | Professional required |
| Utility Approval | Not required (HB 5340) | Required |
| Permanent Installation | No | Yes |
| Transferable | Yes — takes with you | No — stays with home |
| Federal Tax Credit | Not available* | Expired Jan 1, 2026 |
| CT Incentives | Not eligible for RRES | RRES program eligible |
| Annual Output | 1,400-1,800 kWh | Based on system size |
| Annual Savings | $115-150/year | $1,000-2,500/year |
*Note: The federal Residential Clean Energy Credit (Section 25C) expired January 1, 2026 for solar. Contact a tax professional for current guidance.
Yes. HB 5340, signed into law in May 2026, explicitly allows portable plug-in solar photovoltaic systems up to 1,200 watts without requiring utility approval. This legalizes what was previously in a gray area.
No. Under HB 5340, systems 1,200 watts and below do not require utility notification or approval. You can simply set up the system and plug it in.
Most plug-in solar systems are grid-tied, which means they shut off during outages for safety. Some systems with battery backup can provide power during outages. Check your specific system's capabilities.
That's the advantage — you unplug and take your system with you. Plug-in solar is fully portable, making it ideal for renters and those who relocate frequently.
Yes — after the initial equipment purchase, the sun provides free energy. There's no fuel cost, and maintenance is minimal (occasional cleaning).
Most plug-in solar systems are designed to plug into a standard outdoor (GFCI-protected) outlet. Some higher-output systems may require dedicated circuits. Always follow manufacturer installation requirements.
