研究目的

To study the performance of 1.25 kWp GBIPV system, in accordance with IEC 61724 standards and International Energy Agency (IEA) photovoltaic power system task II guidelines. The study also emphasises the optimum inclination angle, and azimuth angle for installation of a BIPV system in residential buildings. The experimental results of the BIPV plant are compared with simulation results obtained from the HOMER optimisation tool. The economic feasibility of GIBPV system for residential buildings in Tamil Nadu state is estimated using HOMER simulation tool.

研究成果

The integration of the photovoltaic module into the building structure is a challenging task with respective power generation of PV module and the effect of incident solar radiation. This study evaluates the performance of 1.25 kWp GBIPV system, to experimentally simulate the performance of the BIPV modules on the outdoor environmental condition. The GBIPV plant was monitored during the year 2016 and various parameters are analysed. The annual energy export to the grid is found to be 1791 kWh. The final yield (Yf) of the GBIPV system ranged from 4.7 to 6 h/day with an average value of 5.1 h/day. The average annual capacity utilisation factor is found to be 23%. The annual average PR of the system under study is 0.83 which is almost high when compared with the globally existing selected PV and BIPV systems.

研究不足

The performance of the GBIPV depends on geographical location, PV efficiency, climatic condition, azimuth and inclination angle of the PV array and the performance of inverter.
