Photovoltaic-Concentrated Photothermal (PV-CPT) System Performance Dataset: Experimental Data Under Variable Flow Rates

This dataset contains experimental data of the Photovoltaic-Concentrated Photothermal (PV-CPT) system based on spectral splitting technology. The research focuses on the performance of the PV-CPT system under different operating conditions (e.g., variable flow rates). The dataset includes key parameters such as solar irradiance, flow rate, inlet/outlet temperatures of the photothermal cycle, PV module temperature, ambient temperature, maximum power point voltage/current of the PV system, as well as core performance indicators including photovoltaic conversion efficiency, photothermal energy/exergy efficiency, and total energy/exergy efficiency of the system.
