GreenSource Energy started where most California solar companies did: on rooftops. The company grew into construction, and under its ADU Concepts name became one of Southern California's busiest accessory-dwelling-unit design-build firms, part of the TESH Group family of companies.
Energy never left. As TESH Group built out a vertically integrated platform for steel-framed housing, with NAXA Design for engineering and permitting, Cal Steel Modular for fabrication, and TESH Incorporated as the general contractor, the parking lots around those buildings kept asking the same question: who covers them, who powers them, and who makes it one contract.
GreenSource Energy is the answer. We bring a curated set of manufacturing and engineering partners, a solar carport system fabricated in Commerce, California, a charging hardware line, and a charging-station engineering firm, to the clients TESH Group already serves, and we deliver them as the licensed contractor with our own foundation, steel, and electrical coordination.
