The maximum electricity conversion efficiency of the Solar Photovoltaic panel is 8-18% under the Standard Test Condition (STC) temperature of 25?C. The atmospheric temperature of Indian climatic condition is mostly above 30?C - 45?C, it incites 30?C-80?C heat over the panel since black body of the PV panel observe more heat, and this temperature majorly affect the electrical efficiency of the panel. The newly designed Glass to Glass Photovoltaic Thermal System (G2G-PVTS) is a combined Photovoltaic (PV) and Flat Plate Solar Water Heating System (FPSWHS). In this technology, the water act as a coolant inside the Copper fins and it absorb the heat of the PV panel and stored in the insulated storage tank by way of natural flow of water. The test result shows that the G2G-PVT electrical efficiency was 0.7% higher than conventional G2T- PV panel, and in addition that 44.37% of thermal efficiency was also stored. The simultaneous conversion of electrical and thermal energy was obtained by this system with effective space utilization. The overall efficiency of the G2G-PVTS panel was improved.
