Solar Refrigeration: NASA Commercial Invention of the Year

The patented technology used in PolarPanel systems was developed at the Johnson Space Center (NASA). It works by directly connecting solar panels to a refrigeration unit, and storing excess energy as ice to maintain temperatures without sunlight and reduce diesel consumption.

Ending the Fossil Age:
Eliminating Diesel from Refrigerated Rail

Every TRU burns an estimated $20,000-$25,000 in diesel annually. In addition, new emissions regulations from the California ARB require the replacement of non-compliant generators every 7 years. PolarPanel systems slash these high operational expenses & headaches.

The Business: Retrofit Existing Refrigerated Transportation

With facility space at Bucyrus Railcar Repair, PolarPanel will fulfill orders from cold chain owners and lessees to retrofit existing railcars, trucks, and containers. PolarPanel looks to provide a certification model that would allow independent shop owners to offer system maintenance.



PolarPanel is a Forbes 30 Under 30 renewable energy startup focused on bringing clean, reliable, and low-maintenance refrigeration technology to the commercial cold chain.


Refrigerated shipping is the perfect target for PolarPanel's mission to promote efficiency and slash maintenance with a solar-powered solution to refrigerated transportation that reduces diesel consumption.


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.
