Founded in 1991, Suntrek Industries initially focused on solar pool heating. Roy Heine, our founder, designed and patented a system designed to produce maximum solar heat to pools while retaining the ability to be completely customized. He researched all available materials to find the most durable - some of which were used in the space shuttles for their superior performance and durability. As the company grew, demand for other solar options developed. The company began offering solar hot water soon after it started, and in the early 2000's Suntrek began offering photovoltaic systems. We now boast a photovoltaic engineering department, NABCEP certified employees, and affiliations with the top PV manufacturers in the world, including SunPower, SolarWorld, Suntech and Sharp. Consistent themes that have run through the company from the beginning are utilizing the best available technology, aligning with the best manufacturers in the business, and a dedication to customer satisfaction. These values have led to the company growing from its humble beginning in Roy's garage to eight regional offices in four states. Suntrek is a licensed solar energy contractor in California (Lic#859460), Nevada (Lic#0039030, 0070340), Arizona (Lic#ROC255609, ROC250353) and Utah (Lic#7532981-5501).
