Our Customers Love Us

Real reviews from homeowners across Maryland, Delaware, and Pennsylvania.

★★★★★
“Best purchase ever. Our rep was fantastic. The install crew was friendly and fast. When there was an electrical equipment failure, they were out and fixed it the same day. The team is always following up to ensure I am happy.”
Brent H. Millersville, MD
★★★★★
“Absolutely recommend American Sentry Solar. We had been planning to go solar for a few years but had so many questions. We were very skeptical. From start to finish our experience was very pleasant. From explaining the process, and answering all our questions to installation they did a phenomenal job.”
Anuradha V. Townsend, DE
★★★★★
“Professional team who communicated well with me and made the installation process easy. I would highly recommend them to anyone. Overall, going solar and owning your own system is a no brainer — for our planet, our family’s future and even the marketability of your own home should you choose to sell. I love my new system.”
Ted H. Berwyn, PA
