American Sentry Solar

What American Sentry Solar does

American Sentry Solar is a Mid-Atlantic residential and commercial solar installation contractor operating as a division of American Design and Build, Ltd., a privately-held home improvement firm founded in 1993. Established as a standalone solar division in 2009, the company designs, sells, and installs grid-tied photovoltaic systems using monocrystalline solar panels paired exclusively with Enphase microinverter technology, including the Enphase IQ Battery 5P energy storage product. It serves homeowners primarily in Maryland, Delaware, and Pennsylvania, with a newer expansion into Texas, plus a commercial EPC vertical targeting non-profits, municipal, and industrial customers in the Mid-Atlantic.

The company's core technology stack is conventional and supplier-validated rather than proprietary: monocrystalline PV modules, Enphase distributed microinverter architecture, IronRidge XR100 rail mounting, and Roof Tech RT-MINI II self-flashing bases rated for 180 mph wind speeds. Revenue is generated through multiple streams: one-time residential and commercial system sales, recurring Solar Power Purchase Agreements (PPAs) with zero upfront cost to the customer, battery storage attach sales, and roofing services delivered through the parent company's CertainTeed ShingleMaster Premier credential.

Go-to-market is a hybrid direct-to-consumer model anchored on in-home consultation appointments set by a centralized call center, door-to-door field sales, paid digital (Google/Facebook), broadcast (radio/TV), community events, and a mobile-app referral program paying up to $1,000 per closed deal. American Sentry Solar is an Enphase Platinum Installer (reportedly the only one in its service area), holds NABCEP PV Installation Professional certification, maintains a BBB A+ rating, and has appeared on Solar Power World's Top Solar Contractor list every year since 2013. The company is founder-led by Joseph A. Tunney with a senior team that has collectively overseen more than $165MM in cumulative solar PV system sales over the past decade, and reports over 100MW of installed solar capacity across residential and commercial projects.
