Munich’s local transport company (the MVG, short for Münchner Verkehrsgesellschaft) has just initiated testing of a solar trailer that can be hitched to its existing buses, promising to lower their carbon footprint quite significantly every year. The trailer is covered in solar panels provided by Sono Motors, and it helps save fuel by providing power for heating, ventilation and air conditioning, as well as the trailer’s steering system.
The MVG says that the trailer could potentially help save up to 2,500 liters of diesel per year per vehicle and also reduce CO2 emissions per vehicle by over 6.5 tons. This is achieved through the use of 20 semi-flexible photovoltaic panels from Sono Motors (the same tech it uses in its first production model, the Sion).
