Students present Stella Juva: the world's first solar-powered ambulance.

Solar Team Eindhoven — the student team from Eindhoven University of Technology with four consecutive Cruiser Class victories at the Bridgestone World Solar Challenge — has announced its most ambitious concept to date. Stella Juva is the world's first ambulance designed to run entirely on solar energy while simultaneously powering the medical equipment it carries onboard.

The vehicle targets a specific gap in global healthcare: regions where conventional ambulances are difficult, costly, or unreliable to deploy because fuel supply is unstable, charging infrastructure is absent, or roads are too rough for medical vehicles. In those regions, a self-sufficient mobile clinic that can drive long distances, diagnose on-site, and recharge medical equipment from sunlight addresses a problem that existing emergency services cannot solve.

Road approval in the Netherlands is targeted for July 2026, with live field testing at planned NGO partner sites scheduled for August 2026. The team is building on a portfolio that includes Stella Vita, the long-distance solar camper, and Stella Terra, the first off-road solar vehicle, which completed more than 1,000 km across Morocco including desert terrain.

A solar vehicle's energy budget is dominated by vehicle mass. An ambulance, however, must meet rigorous safety and handling standards and carry several hundred kilograms of medical payload. Reconciling those constraints — low vehicle mass, predictable braking behaviour, and reliable operation across rough or remote terrain — is one of the central engineering challenges in the build.

Tuningsupply is supplying critical Wilwood braking and vehicle-control components for Stella Juva: an electronic parking brake retrofit kit, remote master cylinders, and an adjustable proportioning valve. Together, these components support braking control, vehicle holding, and brake-balance adjustment under changing payload, traction, and field-test conditions.

Following road approval in July 2026, Solar Team Eindhoven will deploy Stella Juva at planned NGO partner sites to validate the vehicle in the operating conditions it was designed for. The test program is designed to demonstrate three things: that the vehicle can transport patients in terrain where conventional ambulances are difficult or unreliable to deploy, that onboard medical equipment can be powered and recharged from the solar array during operation, and that the vehicle can function as a mobile clinic in locations without grid electricity.
