The integration of photovoltaic modules into the building structure is a challenging task with respect to power generation of PV module and the effect of incident solar radiation. The performance of building integrated photovoltaic (BIPV) modules varies depending upon the orientation and azimuth angle of the building. In this work, the year-round performance and economic feasibility analysis of grid-connected building-integrated photovoltaic (GBIPV) modules is reported for the hot and humid climatic regional condition at Kovilpatti (9°10′0′′N, 77°52′0′′E), Tamil Nadu, India. The appropriate mounting structures are provided, to experimentally simulate the performance of GBIPV modules at various orientations and inclination angles (0° to 90°). The result indicated that the optimum orientation for installation of BIPV modules in the façade and walls is found to be east while that for a pitched roof south orientation is recommended. The overall average annual performance ratio, capacity utilisation factor, array capture loss and system losses are found to be 0.83, 23%, 0.07 (h/day), and 0.17 (h/day), respectively. In addition, the economic feasibility of grid connected PV system for residential buildings in Tamil Nadu, India is analysed using HOMER by incorporating both a net metering process and electricity tariff. Practical application: Grid-connected building-integrated photovoltaic system has many benefits and barriers by being installed and integrated into the building structure. The application of GBIPV in building structures and its orientation of installation needs to be optimised before installing into buildings. This study will assist architects and wider community to design buildings facades and roofs with GBIPV system which are more aesthetic and account for noise protection and thermal insulation in the region of equatorial climate zones. By adding as shading devices, they can reduce the need for artificial lighting, and moderate heating or cooling load of the buildings.

印度南部住宅建筑集成光伏系统的性能评估

就光伏模块的发电和入射太阳辐射的影响而言，将光伏模块集成到建筑结构中是一项艰巨的任务。建筑物集成光伏（BIPV）模块的性能取决于建筑物的方向和方位角。在这项工作中，报告了在Kovilpatti（9°10′0′′N，77°52°）湿热气候区域条件下，并网建筑一体化光伏（GBIPV）组件的全年性能和经济可行性分析。 '0''E），印度泰米尔纳德邦。提供了合适的安装结构，以实验模拟GBIPV模块在各种方向和倾斜角度（0°至90°）下的性能。结果表明，在墙面和墙壁中安装BIPV模块的最佳方向是东侧，而建议在斜屋顶上安装的最佳方向是东侧。总体平均年度性能比，容量利用率，阵列捕获损耗和系统损耗分别为0.83、23％，0.07（h / day）和0.17（h / day）。此外，通过结合净计量过程和电价，使用HOMER分析了印度泰米尔纳德邦居民住宅并网光伏系统的经济可行性。实际应用：并网建筑集成光伏系统通过安装并集成到建筑结构中，具有许多好处和障碍。在安装到建筑物之前，需要优化GBIPV在建筑物结构中的应用及其安装方向。这项研究将帮助建筑师和更广泛的社区使用GBIPV系统设计建筑物的外墙和屋顶，这些系统更加美观，并能解决赤道气候区的噪声保护和隔热问题。通过添加遮阳设备，它们可以减少对人工照明的需求，并降低建筑物的供暖或制冷负荷。
