The company’s work is built on the conviction that reliable photovoltaic engineering requires a deep understanding of physical processes, modelling assumptions and sources of uncertainty, combined with direct exposure to real projects and operational data. R&D at LuciSun is not isolated from practice, but is continuously informed by consulting missions, software development and collaboration with industrial and academic partners. 

LuciSun operates at the interface between scientific research and industrial photovoltaic engineering. This position enables LuciSun to translate research results into operational methods and tools, and to test advanced modelling approaches against real world constraints, data availability and decision making needs. 

Beyond participation in funded projects, LuciSun is regularly involved in the early scientific framing and structuring of collaborative research initiatives, and actively contributes to the preparation and writing of research project proposals in which it is a partner, frequently acting as lead or co-lead author in close interaction with academic and industrial partners. 

Over the years, LuciSun’s R&D activities have focused on a set of core scientific and technical themes that recur across multiple projects. These include advanced 3D modelling of solar radiation and photovoltaic systems, the accurate representation of complex shading environments, the assessment of bifacial and BIPV systems, and the integration of agrivoltaic constraints into PV design and analysis. A strong emphasis is also placed on the quantification and propagation of uncertainties, with the objective of improving the robustness and bankability of PV energy yield estimates. 

A significant part of LuciSun’s research effort is dedicated to the development, validation and benchmarking of modelling tools. This includes the continuous advancement of LuSim and the integration of new data sources such as satellite derived spectral and angular irradiance. Research projects are used to systematically compare modelling approaches, identify their limits of applicability and provide guidance on the appropriate level of complexity required for different use cases. 

LuciSun regularly publishes results in peer reviewed scientific journals and presents its work at international scientific conferences. This activity is an integral part of LuciSun’s R&D strategy, serving as a means to maintain a high level of scientific rigour, to confront methods and results with external expert review, and to remain closely aligned with the latest advances in photovoltaic research.
