Local Home Electrification
Glastonbury is our hometown, and it is where CellSun was built. As a locally owned home-electrification company, we bring nearly two decades of solar and energy experience to every project on this side of the Connecticut River.
From established neighborhoods off Main Street to newer construction near the town center, Glastonbury homes vary widely in roof design, age, and energy needs. We tailor every solar array, heat pump, and roof to the specific home, so you get maximum comfort and savings without guesswork.
One accountable local partner for your whole home, from the roof down to the last circuit.
Premium home solar systems engineered for New England roofs and weather. We size every array around your actual usage, roof orientation, and shading so you generate the most power for the lowest lifetime cost.
Cold-climate KEEN heat pump systems that cool in summer and heat efficiently through Connecticut winters, rated to perform well below zero. We help you access Energize CT rebates and Smart-E financing where eligible.
Solar-ready roof replacements and repairs done right the first time, so your roof and any future solar system work together as one weather-tight, long-lasting envelope.
Whole-home Generac standby generators that keep your lights, heat, and well pump running during outages, sized and installed to protect what matters most when the grid goes down.
Home battery storage that stores your own energy for backup power and resilience, so you rely less on the grid and keep essential circuits powered through interruptions.
Yes. CellSun installs premium solar panel systems, KEEN cold-climate heat pumps, roofing, Generac generators, and battery storage for homeowners throughout Glastonbury and the surrounding Greater Hartford area.
Absolutely. The cold-climate KEEN systems we install are rated to operate efficiently well below zero degrees Fahrenheit, which is colder than Glastonbury typically sees, so you stay comfortable all winter while lowering energy use.
