Why aren’t all buses solar?

3 min read

The concern I am constantly asked when I mention just about anything linked to solar power is this: why isn’t the technologies as ubiquitous as the sunshine?

So now I am energized to share the news that solar-electrical power transportation enterprise Sono Motors is deploying its tech on a bus for the very first time — in partnership with the Münchner Verkehrsgesellschaft (Munich Transport Company, MVG). 

You in all probability know Sono Motors from its work building Sion, the solar electric automobile. The Sono solar engineering replaces conventional paint with proprietary built-in photo voltaic panels that can variety for many programs. Contrary to automobiles with rooftop solar panels by yourself, it will come with 456  photo voltaic half-cells on the hood, fenders, sides, roof, and rear.

I sat down with Laurin Hahn, co-founder, and CEO, to inquire about the lack of photo voltaic deployment up until finally now, and uncover out about the company’s most recent partnership.

He described that the causes for solar’s sluggish start out have been charge and inefficiency: 

10 yrs in the past, solar was just much too expensive and much too inefficient. Now, we have seen price ranges come down by 80% to 90%, and performance likely up by approximately 40% to 50%.

Buses get the photo voltaic therapy

Today the firm is deploying its photo voltaic technology as a diesel bus retrofit answer. As Hahn notes, “There are hundreds of buses in existence. And they will not be put absent tomorrow.” So, the very first move is to reduce the diesel usage of present bus fleets.

Sono Motors’ photo voltaic bus trailer will quickly hit the streets in the Munich metropolitan area, featuring cost savings of up to 2,500 liters of diesel per 12 months for a medium-sized fleet of 300 buses. This could lead to an once-a-year neighborhood CO2 saving likely of much more than 6.5 metric tonnes per bus.

Each and every trailer comes with 20 semi-flexible distinctive photovoltaic (PV) modules, providing in excess of 2,000 watts of vitality to electrical power the vehicles’ battery and electrical loads, these as heating, air flow, air conditioning, and the trailer’s steering system.

Other than saving diesel, the supplemental energy stabilizes the battery’s energy supply. This extends its assistance existence and cuts down routine maintenance prices. The power generated is monitored on-line utilizing integrated application.
