Sono Motors GmbH

Vehicle-integrated photovoltaics form the core business of Sono Motors GmbH, which operates the SonoSolar trademark for commercial mobility applications. The company develops solar modules, charge controllers, telematics and data services, integration engineering, and complete retrofit kits for vehicles. Its standard roof-mounted panels span outputs from 70 W to 500 W and are combined with 12 V or 24 V charge controllers, cables, installation hardware, dashboards, and telematics units. Custom modules can be configured around vehicle roof dimensions, electrical requirements, and design constraints. The systems are intended to supply onboard auxiliary loads and work with both conventional and high-voltage vehicle architectures.

SonoSolar serves commercial vehicle manufacturers and fleet retrofit projects, with applications across trucks, trailers, buses, coaches, vans, refrigerated transport, and campers. Its engineering covers design, validation, and series delivery, drawing on expertise in automotive, solar, digital, and electronics disciplines. The company holds granted patents and pending applications covering charge controllers, vehicle integration methods, and mobile energy optimization. Its Solar Bus Kit has national type approval in Germany, meeting automotive safety, quality, and homologation requirements. Collaboration with vehicle manufacturers includes solar integration work with MAN Truck and Bus, Ford Pro Special Vehicles, Scania, trailer manufacturers, and transport refrigeration unit producers. A reciprocal distribution partnership with Merlin Solar Technologies extends access to SonoSolar controller technology in the Americas and Merlin solar modules in Europe.
