About Ion Solar Pros
Ion Solar Pros, commonly known as iSP, was founded in 2017 by industry veteran Bill Barrieau in Middlebury, Connecticut. The company has since expanded to three Connecticut offices, including a Hartford location at 75 Charter Oak Avenue and a Stamford office, and now serves homeowners across CT, MA, NY, RI, and the greater Northeast. iSP has designed and installed thousands of residential and commercial solar systems backed by a 25-year warranty.
The company is a member of the Connecticut Green Bank Contractor Network and holds NABCEP certification. iSP installs panels from Qcells and REC alongside Enphase microinverters and SolarEdge optimizers, and offers battery storage from Tesla and Enphase. Their team manages every aspect of the solar process, including site assessment, custom system design, permitting, installation, and utility interconnection.
Ion Solar Pros differentiates itself through its Connecticut roots and local expertise. The company understands the state’s net metering policies, utility rate structures, and permitting requirements. iSP offers multiple financing options, including $0-down loans and leases, making solar accessible to a wide range of homeowners in the Hartford area.

Ion Solar Pros designed a system that fit our roof perfectly and maximized production. The Hartford office team was responsive to every question and the installation was completed in one day. Seeing real savings on our electric bill already.

We chose iSP because they are headquartered right here in Connecticut. The sales process was straightforward with no pressure tactics. The crew was professional and cleaned up after themselves.
Tom W.
Good overall experience. The system is performing as promised and customer service has been helpful when I had monitoring questions. The only drawback was a slight delay in getting our permit approved by the city.
