What SolarTech does

SolarTech is a turnkey solar energy solutions provider founded in 2001 and headquartered in El Cajon, California, in the San Diego metropolitan area. The company designs, installs, and services photovoltaic solar systems, battery storage, EV charging infrastructure, and roofing for residential, commercial, multifamily, and non-profit customers across Southern California and Arizona through five office locations. With 15,000+ completed installations over more than two decades, SolarTech operates a vertically integrated model that combines in-house design, permitting, installation, and post-installation service. The company has been recognized as a EuPD Top Brand PV installer for 11 consecutive years, holds TÜV Rheinland QCPV certification, and maintains a 4.5/5-star average across 1,551 customer reviews.

The company's technology stack centers on its SolarFax proprietary monitoring platform, which provides system performance tracking for installed customers, and on its multi-OEM certification strategy — the company is a certified installer for Tesla, Maxeon, REC, Qcells, Enphase, and NeoVolta. This multi-vendor posture allows SolarTech to bundle panels, inverters, batteries, EV chargers, and roofing into integrated offerings rather than depending on a single equipment supplier. The company also operates an ATSC SOLARTECH Vietnam joint venture supporting its battery supply chain, and offers a dealer program that extends its product set through third-party resellers.

SolarTech's business model combines one-time project-based installation revenue with multi-year service and monitoring subscriptions via SolarFax, and tenant-billing solutions for multifamily property owners. Revenue is generated across four customer segments — residential single-family (the largest), commercial, multifamily, and non-profit — through owned offices in California and Arizona plus an emerging dealer channel. Pricing is project-based for installations, while ongoing monitoring and maintenance contracts produce predictable recurring revenue that supplements the lumpy installation cash flows.
