.IDEAS.Fluid.PVTCollectors.Data.Uncovered.UN_Validation

Information

This record contains performance parameters for a flat‑plate, uncovered and uninsulated PVT collector, derived from manufacturer datasheets and thermal rating documentation. Thermal parameters follow the ISO 9806:2013 quasi‑dynamic format and correspond to operation at the PV module’s maximum power point (MPP).

The thermal coefficients were originally obtained using the ISO 9806:2013 unglazed steady-state method, and converted to quasi‑dynamic form according to the procedure detailed in SKN-N0474R0: Thermal Performance Parameter Conversion to ISO 9806-2017.

For this PVT collector, additional real-life measurement data is publicly available (Veynandt, 2023) and has been used in the validation of IDEAS.Fluid.PVTCollectors.PVTQuasiDynamicCollector, which can be found in the IDEAS.Fluid.PVTCollectors.Validation.PVT_UN package.
