Founded by a trio of German friends in 2016, Sono Motors went public in 2021, selling their Sion solar-paneled car, which is also a home energy storage system.
Now, in partnership with the Munich Transport Company (MVG), a novel solar bus trailer will soon hit the roads, carrying passengers in daily operation.
The Sono Solar Technology is offering possible savings—per bus—of up to 2,500 liters of diesel each year and a reduction of 6.5 metric tons local CO2.
The bus trailer will be pulled by a conventional bus, to provide extra capacity on busy routes. Normally, these huge trailers are powered by diesel fuel.
"In summer, when the air conditioning is in full use, the trailer consumes more electricity than the towing vehicle can supply," a Sono spokesperson told GNN.
