Objective
REPVAIR aims to transform photovoltaic (PV) asset management by shifting from a replace-on-failure paradigm to a predictive, climate-aware and repair-oriented lifetime extension strategy. Its objective is to reduce degradation in crystalline silicon PV modules, extend their service lifetime, and improve reliability, resource efficiency and long-term energy yield across Europe’s rapidly expanding PV fleet. By addressing early failures and hidden underperformance in modern high-efficiency modules, the project lowers operational expenditure, reduces waste and strengthens the sustainability and competitiveness of solar energy.
REPVAIR develops an integrated framework combining climate modelling, artificial intelligence, advanced materials and robotics. Climate-driven dynamic ageing methodologies translate European environmental conditions into representative multi-stressor accelerated tests, enabling robust degradation modelling and probabilistic lifetime prediction. AI-based fault detection and classification algorithms are embedded within a federated digital twin architecture, allowing predictive monitoring across multiple PV plants while preserving data confidentiality. Innovative repair techniques targeting dominant electrical and material-related failure modes are validated to ensure restored performance, safety and durability. These repair workflows are translated into a deployable robotic diagnosis and repair system capable of in-field interventions. All results are integrated into a decision-support platform combining diagnostics, lifetime modelling and LCA/LCC assessment to optimise repair-versus-replacement strategies and reduce the Levelised Cost of Energy.
REPVAIR directly contributes to Horizon Europe objectives on sustainable, secure and competitive energy supply by improving reliability, optimising operations and maintenance, enhancing circularity and reinforcing EU technological leadership in digitalised renewable energy systems.
