Based on above discussion, it can be summarized that many researchers worked differently in order to make this industry commercialized to have green energy.
Efficiency of PV/T is high compared to normal water heating systems.
Further, use of PV module and insulation can further improve its design configuration.
Hybrid systems can positively be incorporated to make energy supply system consistent the time for having no interruption in day To day activities of domestic sectors.
Different collector configurations and module arrangements have also been investigated for reasonable output.
It has been proven that 50 percent efficiency is obtainable in combined PV collectors. It is indeed a remarkable achievement in PV/T sector.
