Detailed Profile

American Sentry Solar has been in business since 1993, making them one of the longest-operating home improvement contractors to pivot into solar in the Mid-Atlantic region. Founded by President Joe Tunney in Bel Air, Maryland, the company began its solar division in 2009 and now serves homeowners across Maryland, Delaware, Pennsylvania, and Texas. Their 17-year solar track record in the Delaware market gives them a depth of local permitting and utility interconnection experience that newer entrants simply have not had time to accumulate.

The company's customer reviews tell a consistent story. With a 4.6-star Google rating across 435 reviews and a 5.0 rating on HomeAdvisor, American Sentry Solar has built a reputation for professionalism, installation quality, and responsive communication throughout the project lifecycle. Customers regularly cite the thoroughness of their site assessments, the cleanliness of their work areas, and the promptness with which the team answers follow-up questions after the system goes live. Their NABCEP-certified installers bring the kind of credentialed expertise that distinguishes serious solar contractors from companies that treat installation as an afterthought.

American Sentry Solar has partnered with Enphase to offer the Encharge 10 battery storage system, positioning themselves to serve Delaware homeowners who want energy resilience beyond basic grid-tied solar. The company's BBB profile is notably strong: they hold an A+ rating and have been recognized as a BBB Torch Award winner in both 2001 and 2021, an honor that recognizes sustained ethical business practices over time. They also maintain memberships with SEIA and have been featured in Solar Power World's installer rankings.

Our evaluation did identify a small number of reviews mentioning high-pressure sales approaches and pricing concerns. These reports were not widespread enough to significantly affect the company's overall score, but they are worth noting for homeowners who prefer a low-pressure consultation process. The overwhelming majority of verified feedback paints a picture of a well-managed, experienced operation that delivers on its promises.

With a composite score of 71.7 out of 100, American Sentry Solar earns the second-ranked position in Delaware for 2026.
