PolarPanel is a renewable energy startup focused on bringing clean, reliable, and low-maintenance refrigeration technology to the commercial cold chain. We retrofit existing refrigerated railcars with solar technology to eliminate diesel fuel and generator costs and reduce emissions. As a low-cost and green alternative to commercial trucking, rail is the perfect match for PolarPanel's mission to promote efficiency and slash maintenance with a solar-powered solution to refrigerated transportation. Winner of NASA's Invention of the Year, the patented solar-refrigeration technology used in PolarPanel systems has successfully passed stress testing by the U.S. Military and World Health Organization.
