In Munich, Germany, Sono Motors announced it will equip the city’s fleet of public buses with trailers topped with 20 semi-flexible solar panels. The modules cover 12 square meters and supply the 24V battery with over 2,000W. The solar energy generated will be used to operate the HVAC system and support the trailer steering system. This saves the bus from burning diesel and stabilizes the battery’s energy supply, lowering maintenance costs and extending battery lifecycle. A fleet of 300 buses might save about 2,000 metric tons of C02 emissions each year. The carbon impact of production would be offset in less than one year of operation.
