The full potential of the Dutch residential solar sector is still untapped, as renters face barriers to the adoption of solar PV systems. These barriers are caused by the mismatch between the PV panel lifespan and the rental contract period of rental properties. This thesis studies the implementation of a product-as-a-service business model for the case of balcony PV systems. By virtue of its flexibility, the business model allows tenants to consider solar energy solutions, hence expanding the residential solar PV market. In addition, the business model applies strategies designed to enhance its circularity, which in turn contributes to enhancing the circularity of the Dutch PV sector. Numerous concepts were developed and evaluated to decide on the winning concept, which consists of a compact, modular PV system that can be easily installed on a wide range of balconies while preserving their aesthetics and offering an optional privacy feature. The business model proved to be profitable for both the company and the end-users, with an Internal Rate of Return (IRR) in the range of 6.1 and 7.6% and cost savings ranging between 12 and 17 €/year. From an environmental perspective, electricity generated under this business model was found to have an 80% lower carbon footprint than the electricity drawn from the grid. Ultimately, this research offers interested stakeholders a blueprint for a novel application of the product-as-a-service business model, that if put into practice can accelerate the adoption of solar PV solutions.
