This model validates the electrical performance of the PVT_UN collector, an uncovered and uninsulated PVT collector, using the same 58-day outdoor dataset as the thermal model (Veynandt et al., 2023).
The model uses the PVWatts V5 formulation and includes:
The PV cell temperature is derived from the thermal model using a two-node coupling via UAbsFluid, ensuring accurate representation of the thermal-electrical interaction.
Despite the presence of extreme weather conditions, including wind speeds up to 10–12 m/s and continuous pump operation, the electrical model remains robust. Validation shows excellent agreement with measurements, with a normalized MAE of 5.2 % and nRMSE of 9.9 % (Meertens et al., 2025).
The model's accuracy confirms the reliability of the datasheet-based estimation method for UAbsFluid, even under challenging real-world conditions.
