The \u201cMatrix\u201d architecture, used for the first time in a serial module, delivers up to 90% higher yields under the same conditions \u2013 including partial shading \u2013 compared to conventional modules. The development involved, among others, two Fraunhofer institutes and several vehicle manufacturers. The panels will be manufactured at the company’s new factory in Zwenkau, Germany, starting this fall.<\/p>\n
Significant benefits for diesel-powered commercial and recreational vehicles<\/p>\n
The new solar panel is ideally suited for the growing field of e-mobility in logistics and camping. At the start of production, the primary focus will be on conventional diesel vehicles with larger roof surfaces.<\/p>\n
Trends and Technologies at The smarter E Europe<\/a><\/b><\/p>\n Modern commercial and recreational vehicles are increasingly equipped with main and auxiliary electrical consumers, such as refrigeration units, liftgates, and air conditioning systems. These are currently powered by the diesel engine or the alternator, which increases fuel consumption. <\/p>\n With photovoltaic panels installed on the vehicle roof, solar energy can now supply these electricity-consuming devices, thereby reducing the load on the alternator or engine. This meaningfully lowers operating costs and CO2 emissions.<\/p>\n Smarter E AWARD 2025: Energy Transition pioneers shortlisted<\/a><\/b><\/p>\n \u201cPhotovoltaics on commercial vehicles is not an eco-niche but economically viable. Even light commercial vehicles equipped with 800 watts of solar power can achieve fuel savings of up to 9%. We estimate the market potential in the EU at over 20 GW of solar capacity annually,\u201d says Robert H\u00e4ndel, CEO of Opes Solar Mobility.<\/p>\n A standard semi-trailer, for example, can generate up to 5 kW\u2014equivalent to the output of a typical residential rooftop system. At the same time, battery life is extended and deep discharges can be prevented.<\/p>\n Technology mix solves key challenges simultaneously<\/p>\n Solar modules on vehicles are continuously subjected to vibrations and shocks, and they experience heavier dirt buildup than conventional stationary solar systems. In addition, they are constantly exposed to changing shading conditions. O.Motion combines various technologies to address these challenges.<\/p>\n The core innovation lies in the newly developed Matrix architecture, where solar cells are arranged in a masonry-like pattern. Unlike traditional modules that rely on soldered busbars, the cells are interconnected using a highly conductive specialized adhesive for electrical contact, eliminating the need for ribbon soldering.<\/p>\n
