J.v.G. technology GmbH

Founded in 1997, J.v.G. technology GmbH is a private headquartered in Freystadt, Germany specializing in Solar.

J.v.G. technology GmbH is a Bavarian engineering company specializing in complete turnkey solar photovoltaic (PV) module production line solutions. Founded in 1997 by Hans Thoma, the company pivoted into the solar industry in 1998 and launched its first production lines in 2001. The firm is led by founder Hans Thoma and his sons Patrick and Andreas, maintaining a family-owned structure focused on long-term partnerships and engineering integrity. The company's core offering is designing, manufacturing, and installing customizable PV production lines ranging from 25 MW to 1,200 MW capacity. Services include factory layout planning, equipment installation, staff training, technology transfer, and ongoing operational support. A defining innovation is DESERT Technology—a proprietary system developed over 15 years in collaboration with the EU and Fraunhofer Institute—specifically engineered for extreme environments (desert heat, high humidity, sandstorms, UV radiation). Key technical features include anti-soiling coatings, high-temperature resistance up to 125°C, PID-free design, humidity-resistant diamond foil, and modular equipment designed for future upgrades (PERC, TOPCon, HJT). J.v.G. positions itself as a technology partner rather than a transactional supplier, emphasizing direct access to founders, personal project accountability, comprehensive spare parts inventory, proactive maintenance, and post-commissioning support. The company has deployed projects across Africa, the Middle East, Asia, and Europe.
