CellSun helps Marlborough homeowners cool and heat their homes efficiently, cut energy bills, and stay powered through outages with premium solar, KEEN heat pumps, roofing, generators, and battery storage.
Local Home Electrification
Marlborough is the smallest and most rural town in our service area, with large wooded lots spread along Route 66, Jones Hollow, and West Road. Most properties are on private wells and septic rather than public utilities.
That single fact reorders the priorities. When the power goes out here, the well pump stops and the house loses water, not just lights, which is why standby generators and battery backup lead most Marlborough conversations.
Larger lots also open options that dense towns cannot support. Where the tree canopy shades the roof, a ground-mounted array in a clear part of the property is often the better design, and there is usually room for it.
Marlborough permitting is handled by the town Building Department, and ground-mounted arrays require a zoning setback review in addition to the building and electrical permits. Well and septic locations are confirmed before any trenching.
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 heat pump systems rated to heat efficiently well below zero. CellSun does the load calculation, system design, permitting, electrical work, and Energize CT rebate paperwork. The installation is performed by our licensed HVAC installation partner.
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.
Because most homes here run on a private well. When the grid drops in Marlborough the pump stops and the house loses running water, so a standby generator or battery restores water service as well as lighting and heat.
Often yes. Wooded lots around Lake Terramuggus and Jones Hollow shade many roofs, and Marlborough's larger parcels usually have a clear area where a ground-mounted array outproduces anything the roof could support.
CellSun contracts for solar, roofing, generators and battery storage, and does its own electrical. On heat pumps CellSun designs and permits, and our licensed HVAC installation partner installs.
Yes. The systems we specify run efficiently well below zero, colder than Marlborough typically sees.
