Connecticut passes HB 5340 solar bill

Solar policy is usually about rates, tariffs, and acronyms. But this Connecticut bill is really about something simpler — whether it stays easy and worthwhile to put solar on a roof, in a field, or eventually in a window-facing apartment. On May 6, the General Assembly passed HB 5340 and sent it to Gov. Ned Lamont. If he signs it, Connecticut gets a new long runway for rooftop and shared solar, plus a few genuinely new ideas mixed in. ### What actually passed? HB 5340 is a big renewable-power package, not a narrow rooftop-solar tweak. It passed at the end of the 2026 session and bundles together successor programs for residential, nonresidential, and shared clean energy projects, along with consumer-protection studies, agrivoltaics, and an environmental-justice pilot. In plain English — lawmakers decided not to let Connecticut’s current solar framework just run out and hoped for the best. (cga.ct.gov) ### Why is 2035 the headline number? Because the existing state incentive programs were set to expire next year. The new bill pushes residential, commercial, and community-style solar incentives out to 2035, which gives installers, homeowners, and lenders a much longer planning horizon. That matters more than it sounds — solar markets hate cliff edges, and “program ends soon” is how projects stall. (legiscan.com) ### What’s the deal with plug-in solar? This is the eye-catching part. The bill explicitly allows portable solar photovoltaic systems — basically small plug-in units rather than a full traditional rooftop install. Bill trackers summarizing the final language say the cap is 1,200 watts, limited to one device per customer meter, and exempt from a standard interconnection agreement if safety rules are met. That opens a path for renters, condo residents, or anyone who cannot do a full roof project. (ctmirror.org) ### Why does permitting matter so much? Because soft costs are where a lot of solar pain lives. The hardware got cheaper years ago, but paperwork, inspections, and local approval delays still drag projects out and raise installer costs. HB 5340 includes permitting changes meant to speed that up. That is less flashy than plug-in panels, but for actual deployment it may be the more important change.

One is an agrivoltaics program — solar paired with active farmland instead of treating energy and agriculture as mutually exclusive. The other is a pilot to install solar systems at low or no cost for 100 households in environmental-justice communities. So this is also trying to answer the fairness question, not just the megawatt question. (pv-magazine-usa.com) ### Why are critics pushing back? The fight is over electric bills. Republicans argued the incentive extension could add about $850 million to the public benefits charge over 10 years. Supporters counter that distributed solar can lower grid costs, cut pollution, and give households a hedge against high utility rates. Basically, both sides are talking about affordability — they just disagree on whether subsidies raise costs now or avoid bigger costs later. (legiscan.com) ### Why the East Windsor and Enfield pause? The bill also includes a one-year moratorium on siting large-scale solar arrays in East Windsor and Enfield, towns that already host a heavy concentration of solar projects. That tells you this was a coalition bill — not just “more solar,” but “more solar with some local brakes where backlash is building.” (ctpublic.org) ### Bottom line HB 5340 is Connecticut choosing continuity over a policy cliff, but also experimenting at the edges. The big win is certainty through 2035. The interesting bet is plug-in solar — a small-device idea that could make solar less like a home renovation and more like an appliance.
