Geometric Shingled Semi-Transparent Solar Panels
SUNTRANS develops next-generation semi-transparent panels designed specifically for electric buses and utility EVs. Using a geometric checkerboard layout of shingled cells, the panels deliver high efficiency while allowing controlled transparency. Advanced encapsulation and vibration-resistant lamination ensure long-term durability under real vehicle conditions. Early prototypes reach 15–18% efficiency, outperforming conventional semi-transparent PV solutions.
Colored Curved VIPV Panels
Our colored curved panels bring aesthetics, efficiency, and resilience together. UV-stable polymers and spectral-selective coatings preserve color quality with minimal performance loss—under 2%. Flexible, lightweight structures resist microcracks and are optimized for curved bus roofs and side panels, supporting brand identity without compromising energy generation.
High-Efficiency Power Converters for Solar E-Mobility
SUNTRANS integrates five converter types into a holistic power-electronics ecosystem supporting vehicle-integrated PV converter, PV-Side DC-DC, charging stations, storage, and grid interaction. All converters exceed 98% efficiency, withstand partial shading, and comply with automotive EMC standards. This unified approach maximizes energy harvesting and prepares fleets for advanced services like dynamic MPPT and demand response.
PV-Integrated Charge Hub Architecture
The project introduces a scalable DC-based architecture that links PV arrays, local storage, and EV chargers through a single efficient bus. This reduces energy losses by 5–8% compared to typical AC systems. The modular design adapts to small and large fleets and will be validated in pilot sites in Türkiye, Romania, and Spain.
AI-Driven Fleet and Energy Management Platform
Our real-time AI platform intelligently coordinates solar generation, storage, and fleet charging. It adapts instantly to weather shifts, route changes, and grid signals, enabling peak shaving, frequency regulation, and optimized charging schedules. With full interoperability (OCPP, ISO 15118) and integrated LCA metrics, it offers a future-proof tool for solar-powered fleet operations.
Streamlined VIPV-Ready Manufacturing
SUNTRANS redefines how VIPV is integrated into electric vehicles by aligning the process with existing production lines. Through laser-cut frames, robotic welding, and quick-connect harnesses, manufacturing overhead is kept to ≤5% additional cycle time. The result is a scalable, OEM-ready blueprint for mass adoption of VIPV in buses and last-mile EVs.
