Based in Fontana, California, this industry leader has focused on solar thermal technology since its inception in 1978. The firm specializes in the engineering and production of high-performance solar water heating collectors and integrated mounting hardware. By providing durable components and full systems, they support renewable energy infrastructure across various distribution channels. Their primary manufacturing facility operates using a substantial photovoltaic array that generates enough clean electricity to power all office and production needs. Environmental stewardship extends to the building design, which incorporates natural daylighting and high-efficiency lighting to reduce energy consumption. On-site water conservation is achieved through waterless plumbing fixtures and the use of drought-tolerant landscaping. This commitment to sustainability ensures that every solar product is manufactured within a low-impact and energy-independent environment.
