Hello PVsyst community,
I am working on a research project focused on the long-term aging and performance degradation of Building-Integrated Photovoltaic (BIPV) systems. To accurately model this, I need a more detailed understanding of PVsyst's internal calculations.
I have already reviewed the official documentation, but I have a few specific questions that I'm hoping for some clarity on:
Temperature Modeling for BIPV: I understand that PVsyst does not have a detailed building model for BIPV. The documentation suggests importing a custom temperature time series. Could you please provide more insight into the specific equations used in the internal thermal model for BIPV (or non-ventilated modules)? For example, are there any specific heat transfer coefficients or thermal resistance parameters that can be adjusted to better simulate the higher operating temperatures of BIPV modules?
Losses and Aging Equations: I need to understand how the software models long-term performance losses. Could you elaborate on the mathematical models or equations used for
Thank you in advance for any documentation, white papers, or detailed explanations you can provide. Your insights will be invaluable to my research.
