The van
On-board solar system
A deployable photovoltaic roof to produce the energy of the journey directly from the sun.
On-board solar system
The technological heart of Soleva is its innovative photovoltaic system. Developed by CSEM in collaboration with the EPFL PV-Lab, the lightweight, deployable solar panels produce the energy needed for driving and life on board. Thanks to V2X (Vehicle-to-Everything) technology, the van becomes a mobile solar power station capable of powering events, festivals and public services.
Key characteristics
- High-performance solar panels developed by CSEM and the EPFL PV-Lab
- 1,350 W of on-board solar power
- Lightweight, reinforced, hail-resistant structure
- Deployable system to maximize the capture surface
- Recharges up to 150 km of range per sunny day
- V2X technology: external power for events and services
- BRUSA HyPower DC-DC converter optimizing the panels → battery flow
Our approach
- 01
Design
Developing panels adapted to the roof surface, in collaboration with CSEM and the EPFL PV-Lab.
- 02
Manufacturing
Producing lightweight honeycomb-structured modules, weather-resistant, made in Switzerland.
- 03
Integration
Installing the deployable system on the van roof with an adjustment mechanism to optimize orientation.
- 04
Optimization
Calibrating the complete energy chain: panels → converter → battery → propulsion and habitat.
Frequently asked questions
Does the van run on solar power alone?
The goal is to maximize solar autonomy. In favorable conditions, the panels provide up to 150 km of charge per day. The van can also be recharged at standard charging stations.
Who developed the solar panels?
The panels were developed by CSEM (Swiss Center for Electronics and Microtechnology) in collaboration with the EPFL PV-Lab, two leading institutions in Switzerland.
Can the solar system be adapted to other vehicles?
That is one of the project's ambitions: to demonstrate that this technology can be transferred to other utility and professional transport vehicles.
The other pillars
Electric conversion
An old combustion van transformed into a 100% electric vehicle through retrofit.
