Green Power Energy

15*Years in Business
AnnandaleLocation

Green Power Energy has been a trusted name in solar installation across the Mid-Atlantic and Southeast since its founding over 15 years ago. The company operates from its home base in Annandale, New Jersey, but has built a meaningful presence in Alabama through regional partnerships and a willingness to travel for projects that other installers pass on. What pushed Green Power Energy to the number one spot in Alabama was the combination of their customer satisfaction track record, clean BBB record, and the consistency of their installation work across a wide geographic footprint. Our evaluation team flagged them as an outlier in a state where many solar companies are relatively new or lack robust review histories. Their 4.7-star Google rating across 531 verified reviews shows the kind of steady, repeat-customer momentum that is difficult to manufacture. The company employs NABCEP-certified professionals and has earned manufacturer certifications from several tier-one equipment brands. Their crews work across residential and commercial projects, and they have developed a streamlined process for handling out-of-state permitting requirements. Green Power Energy has also been recognized for their customer education approach. Rather than pushing a single equipment package, they walk homeowners through the trade-offs between different panel and inverter combinations, tailoring each system to the specific roof orientation, shading conditions, and energy usage patterns of the home. With a composite score of 77.4 out of 100, Green Power Energy is our top-ranked solar company in Alabama for 2026.

*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.
