The performance of building integrated photovoltaic (BIPV) system depends on the geographical location and the incident angle of solar radiation. In this paper, a simple mathematical model has been developed to predict the performance of BIPV modules with and without phase change material (PCM). The effect of transmittance of the BIPV glass cover is studied with respect to incident solar radiation. The performance curves, annual energy and exergy gains are analysed for hot and humid climatic conditions of Kovilpatti (9°10′0′′N, 77°52′0′′E), Tamil Nadu, India. The annual electrical energy gains of the BIPV-PCM for the south orientation is (135 kWh) and the east orientation (110 kWh) obtained the minimum. Similarly, the annual electrical energy of the BIPV-PCM is maximum in the east orientation and minimum in the west orientation. The south orientation BIPV-PCM obtained the maximum energy (190 kWh) and exergy (27.3 kWh). The theoretically calculated results have good agreement with experimental results. Practical application: Integration of photovoltaic modules into the building structure has many benefits and challenges; before integrating into the building structure, the performance and impact of the BIPV module needs to be studied. This study will assist developers and designers to understand the likely performance of the BIPV modules and assess the benefit of integrated phase change materials for application in residential buildings in equatorial climate zones.

构建用于赤道应用的集成光伏模块和相变材料的集成

建筑物集成光伏（BIPV）系统的性能取决于地理位置和太阳辐射的入射角。在本文中，已经开发了一个简单的数学模型来预测具有和不具有相变材料（PCM）的BIPV模块的性能。针对入射太阳辐射，研究了BIPV玻璃盖的透射率的影响。分析了印度泰米尔纳德邦科维尔帕蒂（9°10′0′′N，77°52′0′′E）炎热和潮湿气候条件下的性能曲线，年能量和火用增益。南向的BIPV-PCM的年度电能增益为（135 kWh），东向的（110 kWh）最小。同样，BIPV-PCM的年电能在东向最大，在西向最小。南向BIPV-PCM获得了最大能量（190 kWh）和火用（27.3 kWh）。理论计算结果与实验结果吻合良好。实际应用：将光伏模块集成到建筑结构中有很多好处和挑战；在集成到建筑结构中之前，需要研究BIPV模块的性能和影响。这项研究将帮助开发人员和设计人员了解BIPV模块的可能性能，并评估将集成相变材料应用于赤道气候区住宅的益处。将光伏模块集成到建筑结构中会带来很多好处和挑战。在集成到建筑结构中之前，需要研究BIPV模块的性能和影响。这项研究将帮助开发人员和设计人员了解BIPV模块的可能性能，并评估将集成相变材料应用于赤道气候区住宅的益处。将光伏模块集成到建筑结构中会带来很多好处和挑战。在集成到建筑结构中之前，需要研究BIPV模块的性能和影响。这项研究将帮助开发人员和设计人员了解BIPV模块的可能性能，并评估将集成相变材料应用于赤道气候区住宅的益处。
