03 / What customers say
Trusted by the homeowners next door.
“Teamsun was the only crew that walked the roof, named the panel brand, and answered every question without checking with someone. Same lead tech came back a year later when I added a battery.”
Homeowner · Glastonbury, CT
“Three of my neighbors had Teamsun, so I called them. The crew was on my street five days after I signed.”
Homeowner · West Hartford, CT
“They knew the historic district secretary by first name. Saved us six weeks on permitting alone.”
Homeowner · Glastonbury, CT
“Same lead tech who installed it came back four years later to swap an inverter under warranty. No charge, no excuses.”
