Why choose SunCommon, and why you might not
What SunCommon does well, and where to be careful, compared with the installers it competes with most.
Reasons to choose SunCommon
You can rent, then buy the panelsYou can pay cash, take a loan with no upfront cost, or rent the panels through Participate Energy. You can buy the rented system as early as year 6.
It helps with power company battery plansIf Green Mountain Power is your power company, SunCommon can help you join its battery programs. In one you own the batteries; in the other you rent them. Green Mountain Solar offers this too.
It puts panels on the roof or groundSunCommon puts panels on your roof or on the ground, with Tesla Powerwall batteries. It says it was founded in Waterbury, Vermont, in 2012.
Owners praise helpful staff and careful crewsIts good reviews praise responsive staff, clear explanations of each option and careful install crews. Its Vermont license was active when we checked on October 13, 2026.
Reasons to look at others
It lists no warranty at allSunCommon praises its warranty but publishes no terms: none for its own work, the panels, or leaks where the panels are bolted to the roof. Catamount lists 15 years on its own work. Get every term in writing.
It names no panel brandSunCommon names Tesla Powerwall batteries, but no panel brand. Green Mountain Solar names its exact panel models. Ask for the panel and inverter models in your written quote.
It does not name its lenderSunCommon does not name the lender for its loans. It does not publish the rent plan’s buyout price. Ask for the lender, the terms and the buyout price in writing.
Some owners report surprise chargesIts negative reviews describe missed appointments, surprise charges, and panels that failed under warranty with no visit. Ask who handles warranty service calls after the install.
SunCommon reviews: what customers say
We found no Google or Trustpilot reviews for SunCommon when we checked in October 2026. Ask the company for references from recent customers in your area.
How much does SunCommon cost?
SunCommon does not publish a price for your system; its lease page shows only an average example. Ask for an itemized quote showing the cash price, system size, equipment models and, for a loan or lease, the lender or lessor, rate, payment schedule, buyout price and total cost. Its solar page says advisors share an estimated monthly payment during a free visit. For state price ranges, see our solar panel cost guide; for how the plans compare, see loans, leases and PPAs.

Your written proposal should list the exact panel, inverter and battery models, the system size in kilowatts (kW) and the forecast yearly production in kilowatt-hours (kWh).

SunCommon has no warranty page. We read its lease page, which calls its warranty “the strongest in the business” without terms, and its customer support page on October 13, 2026. Your signed agreement decides what applies.
Its support page says the warranty does not cover damage caused by the homeowner.
Where does SunCommon operate, and which licenses were checked?
SunCommon’s contact form says it currently serves only Vermont and New York, and its homepage says it has operated in Vermont since 2012 and in New York since 2002 (read October 13, 2026). Its careers page names offices in Waterbury, VT and Kingston, NY (read October 14, 2026); its contact page lists only Waterbury. It lists no counties.

Licenses
We found 1 active license record in state registries (October 13, 2026). New York licenses this work through individuals or local permits, not a company license; ask for the license holder’s number. Check the license yourself under the exact business name on your contract. A license check confirms registration, not workmanship quality.
