Solar PV · CT
Solar in Connecticut.
Connecticut electric rates are among the highest in the country. A rooftop array here is about taking that bill back — and keeping it off for decades.
Connecticut
Built for how this market actually runs.
Typical homes here see about $0.30 / kWh and 1,220 kWh per kW per year. We size the system to your bill — then confirm it on the roof.
Eversource and United Illuminating administer Residential Renewable Energy Solutions. You pick Buy-All or Netting on the application Helio files — not both. Buy-All is a locked check. Netting credits the bill at retail, with a $0 REC payment and a Solar Energy Adjustment on 2026 applications.
Income adders of $0.0275–$0.055 / kWh still exist for qualifying households and distressed-community siting. Sales tax and property tax on the equipment are exempt. Helio’s prelim models Buy-All unless your usage profile says Netting wins — we compare both on the roof.
Headquarters is Trumbull. The crews, the interconnection paperwork, and the PURA forms are ordinary Helio work, not a subcontractor surprise.
