Improvement Potential and Sustainability Index of Photovoltaic Thermal Solar Air Collector

Photovoltaic thermal (PVT) system is the future technology that will help in decreasing carbon emissions because this PVT technology generates electricity and thermal simultaneously. The advantage of PVT technology is that it is clean, saves space and cost, et cetera. This research applies an experimental approach in the laboratory and outdoors. The objective of this comparison is to generate real and controlled data and parameters. The analysis conducted is the improvement potential and sustainability index analysis. Both analyses are rarely conducted in PVT technology studies. Mass flow rate used was 0.01 kg/s-0.05 kg/s and sun intensity used was 800 W/m(2). The result indicated the impact of mass flow rate on improvement potential and sustainability index. The higher the mass flow rate, the lower the improvement potential decreased; the higher the mass flow rate used, the higher the sustainability index increased.
