Green Power Energy

0BBB Complaints
17*Years in Business
DurhamLocation

Green Power Energy has built a reputation as one of the most reliable solar installation companies in the Northeast. Founded over 15 years ago and headquartered in Durham, Connecticut, the company has completed more than 1,000 residential and commercial solar installations across Connecticut, New Jersey, and Pennsylvania. What separates Green Power Energy from many competitors is their focus on doing one thing well. Unlike companies that bolt solar onto an existing roofing or electrical business, Green Power Energy was built from the ground up as a solar-first company. Their entire team, from sales consultants to project managers to the installation crews, is trained specifically for photovoltaic system design and installation. That focus shows in their 4.8-star Google rating and their A+ rating with the Better Business Bureau. Green Power Energy earned the top spot in Connecticut for their combination of deep experience, consistently strong customer reviews, clean BBB record, and genuine dedication to solar as their core business. In a state where many "solar companies" are actually general contractors who added panels to their service list, Green Power Energy stands out as a purpose-built solar installer with the track record to back it up.

*Companies displaying 15 or more years in business are typically established electrical, roofing, or general contracting firms that expanded into solar installation in more recent years. The years shown may reflect the age of the parent organization or a strategic partner, not necessarily the solar division itself. This distinction is worth considering when comparing to dedicated solar installers, as purpose-built solar companies may offer more specialized expertise despite a shorter operating history.
