摘要

Part A of this paper demonstrated that the offered PV/T design has effective heat removal that decreases PV cells' temperature, therefore increasing their actual efficiency. Photovoltaic performance and efficiency analysis demonstrate that the electrical efficiency of the system at natural conditions is 6-25% higher than that of PV. The system's electrical efficiency is less influenced by insulation than that of PV, and total efficiency is higher when it is insulated. The H40 regime was found to be more plausible, because it allows the production of up to 50 liters of water at 40 °C and has only 3.5% less efficiency than the most effective T20 regime, which requires up to 193 liter/day circulation water of 20 °C temperature.
