LuciSun actively contributes to the International Energy Agency Photovoltaic Power Systems Programme through Tasks 13, 15 and 16, an international framework that brings together recognised experts from research institutes, industry and public bodies to consolidate best practices in photovoltaic system analysis and modelling. 

Each IEA PVPS Task brings together a focused group of leading researchers and practitioners working on a well-defined technical topic, creating a unique environment for in-depth exchange and collective progress at international level. For LuciSun, participation in these Tasks provides the opportunity to engage in close technical dialogue with experts at the forefront of PV system research, to receive constructive feedback on its developments, and to continuously learn from approaches developed worldwide. 

Through Task 13, LuciSun contributes to work related to PV performance assessment, loss analysis and the interpretation of operational data. This Task provides a structured forum to compare methodologies used internationally for energy yield assessment and performance evaluation, and to discuss their applicability and limitations across different system types and operating conditions. 

Task 15 is explicitly dedicated to building-integrated photovoltaics (BIPV). Within this Task, LuciSun is actively involved in Subtask C, focused on BIPV in a digital environment, and co-leads Activity C2 on BIM-based analysis, simulation and optimisation of BIPV projects. This work addresses the practical challenges of integrating PV simulation within BIM workflows, including interoperability between architectural design tools and energy and PV simulation software, data structuring of BIPV components, and the delivery of credible performance indicators across the building life cycle. Participation in Task 15 allows LuciSun to confront its own tools and workflows with those used by other experts, and to contribute to market-oriented guidance grounded in real BIPV case studies. 

Task 16 focuses on solar resource assessment and associated uncertainties, providing a shared international reference framework for the characterisation of irradiance inputs used in PV simulations. Participation in this Task supports LuciSun’s efforts to maintain consistency between solar resource data, modelling approaches and performance analysis practices. 

Beyond the scope of individual Tasks, participation in IEA PVPS offers LuciSun a long-term platform for technical exchange, informal peer review and synthesis of state-of-the-art knowledge. The technical reports produced within IEA PVPS are widely recognised as some of the most reliable and comprehensive references available on photovoltaic systems, yet they remain underutilised within parts of the PV industry. Contributing directly to the preparation of these reports is both a responsibility and a privilege, and plays an important role in maintaining LuciSun’s scientific discipline, methodological rigour and alignment with current research.
