Electrical Efficiency Investigation on Photovoltaic Thermal Collector with Two Different Coolants

The design and development of a photovoltaic thermal (PVT) collector were developed in this study, electrical efficiency assessed. To improve system performance, two types coolants employed, liquid liquid-based MnO nanofluid. Flow rates ranging from 1 to 4 liters per minute (LPM) for the interval 1.0 LPM together with 0.1% concentration manganese oxide (MnO) Various parametric investigations, including power generation, glazing surface temperature, efficiency, carried out on testing days, which clear sunny. Outdoor studies aforementioned nanofluids liquids at volume flow LPM, can be compared reference freestanding PV system. research levels, thermal, revealed that water nanofluid provides better energy conversion than stand-alone systems. In three different domains examined: PV, PVT collector, nanofluids. achieved lower performed better, an intermediate level.
