Four Corners Solar is a Durango-based design-build construction company specializing in grid-tied photovoltaic systems and larger solar thermal systems. The photovoltaic (PV) systems do not require batteries and are essentially maintenance free. The thermal systems provide pool heating for recreation centers and hot water for large consumers like restaurants and cafeterias, laundromats and car washes. Our professional design and installation teams are NABCEP and CoSEIA-certified. We are bonded and insured and have excellent working relationships with AHJs (planning & zoning, inspectors, etc.) and the utilities (LPEA & Empire). This is important for the timely and cost-effective implementation of large energy projects. Projects include office complexs, universities & rec centers.
