Sono Motors partners with MVG to unveil solar bus trailer in Munich

Sono Motors GmbH has reportedly collaborated with Munich Transport Company (MVG) to unveil a solar bus trailer in the Munich metropolitan area.

The companies intend to test the energy yields and daily usability of the technology.

The solar bus trailer will contain twenty semi-flexible PV (photovoltaic) modules with a combined capacity that exceeds 2 kW. The solar system covers a total area of 12 sq. mt, and powers the battery as well as electrical loads like ventilation, heating, air conditioning, and the steering system.

Sono Motors expects to save diesel up to 2,500 liters per bus per year, and this could increase with the growing efficiency of the power electronics and the PV cells. Thus, a fleet of 300 buses can reduce its CO2 (carbon dioxide) emissions by approximately 2,000 tonnes per year using the solar technology.

Veit Bodenschatz, Head of the Bus Division and Managing Director of MVG, commented that the PV system on the bus trailer enables the company to test the efficiency and feasibility of the power generation under real conditions.

The emissions of the solar solution from production account for up to 1.5 tonnes of CO2 per bus trailer or bus and could compensate in less than a year.

It is worth noting that Sono Motors is the company developing the Sion solar car. The Munich project will be the company’s first stunt in public transportation.

Sono Solar’s complete solution includes the power electronics, solar modules, mechanical and electrical integration, after-sales and service, and telematics and data. It is suitable for integrating into current vehicles as well as new vehicles during the production phase.

A year ago, the company also signed ten contracts and letters of intent with firms like MAN and ARI Motors for a multitude of applications of its solar transport technology.
