VIPV technology is emerging as a promising pathway to enhance the sustainability and autonomy of electric mobility. By generating clean electricity directly on-board, VIPV can reduce dependence on external charging infrastructure and contribute to lowering the carbon footprint of the transport sector. However, its integration into vehicles presents distinct technical challenges that require careful consideration in design, manufacturing, testing, and deployment.

This report explores the main technological aspects influencing the successful integration of photovoltaic systems into vehicles. It examines the challenges of installing PV modules on curved vehicle surfaces, addressing manufacturing techniques, the limits of cell bending, and the effects of curvature on performance. Aesthetics are highlighted as a decisive factor for consumer acceptance, with detailed insights into colouring methods, colour reproducibility, and compatibility with automotive design trends. The weight of the PV system is shown to affect vehicle efficiency, and the report introduces a methodology to balance additional weight against energy yield, demonstrating that parking-phase generation can offset weight-related losses. It also addresses the current absence of dedicated VIPV standards, recommending a tailored safety qualification programme that merges PV and automotive testing protocols. Special testing requirements for curved PV modules are discussed, drawing on results from international round‑robin projects. Finally, the report notes the need to manage potential toxic materials, ensure recyclability, and improve vibration resistance to maintain long‑term system reliability.

Key takeaways

  • VIPV technology faces unique design challenges – including curvature, aesthetics, and weight – that must be addressed to enable effective and reliable integration into vehicles.
  • Standardisation is critical – work is underway to create dedicated testing and safety qualification programmes tailored to VIPV applications.
  • Energy balance depends on multiple factors – such as PV technology choice, vehicle type, and driving/parking patterns.
  • Aesthetics matter for market acceptance – colour, surface finish, and seamless integration into vehicle design are essential for consumer uptake.
  • Special testing methods are required – curved PV modules need tailored approaches to ensure accurate performance assessment and long-term reliability.

The report concludes that VIPV offers significant potential for the automotive industry, but further research, standardisation, and technology development are essential. Improved testing methodologies, optimised electrical designs for curved modules, and PV technologies tailored for vehicle integration will be key to unlocking VIPV’s full potential.
