Wickham Freight Lines takes delivery of Sunswap Endurance solar-powered trailer refrigeration unit in Australia
Published
Electrek reports that Australian trucking firm Wickham Freight Lines has received a production solar-powered trailer refrigeration unit from Sunswap Endurance after a road trial.
Electrek reported on 25 October 2026 that Wickham Freight Lines had received a Sunswap Endurance solar-powered electric trailer refrigeration unit in the preceding week, calling it Australia's first regular production unit of this type with a customer.
Wickham decided to buy the units after a trial this past summer: a Sydney–Brisbane round trip of 1,670 km (about 1,040 miles) with more than 30 hours of driving, which ended with over 65% of battery capacity remaining.
Director Graham Keogh said the unit's performance, reliability and operational savings exceeded the company's expectations. He added that the technology makes commercial sense for its large east coast fleet, which concentrates on refrigerated and cold chain freight.
Why it matters
Electrek says conventional refrigerated trailers depend on diesel generators that run nonstop, emitting CO₂ and NOx and adding noise, whereas the Sunswap unit is reported to keep food and pharmaceuticals cold without diesel fuel.
