OPES Solar Mobility launched its latest Made-in-Germany 500 W vehicle-integrated PV solution at the event
This product features the 'matrix' CIGS cell interconnection technology, said to boost the module’s power density and efficiency
It also offers a unique advantage: only the cells directly affected by partial shading reduce their output, aligning with the dynamic shading conditions typical of vehicle-integrated applications
Intersolar Europe 2025 witnessed multiple niche application PV module makers exhibiting their latest products. OPES Solar Mobility, a German vehicle-integrated PV (VIPV) module maker, exhibited its newly launched 500 W solar mobility solution at its booth during the event.
Product
This flexible module, featuring CIGS cells interconnected using innovative 'matrix' interconnection technology, delivers a power output of up to 500 W by maximizing the panel area for enhanced power density and efficiency. In contrast to the static partial shading experienced by conventional modules, this module’s cell interconnection technology is uniquely designed to adapt to the dynamic shading conditions typical for constant motion of vehicle-integrated modules. Only the cells directly affected by partial shading reduce their output, while the current is passed around the shaded areas.
Although it is a flexible product, the company says it has integrated multiple technological advancements and conducted extensive verifications to ensure greater durability, meeting the demanding criteria of VIPV modules. These modules are subjected to constant vibrations and elevated temperatures due to the constant motion of the vehicle. Unlike conventional rooftop systems that are mounted on substructures, vehicle panels are glued directly onto surfaces, which introduces additional stress from thermal expansion that standard flexible panels are typically not designed to withstand, the company explained. To validate the product's resilience against vibration, airflow, and adhesion, the company’s in-house laboratory tests these solar panels for adhesive strength, thermal performance, vibrations, and shocks.
