One of the most critical challenges is bird dropping deposition (soiling) on a glass surface of the photovoltaic (PV) module in an open environment of Western Rajasthan. This paper has been now exclusively emphasized to focus on effects of the bird dropping phenomenon on the performance of PV systems. The presented study includes the impact of the seasonal bird dropping effect on the reduction in energy yield with various tilt angle configurations. Considering this, the highest level of reduction in power loss was observed at the end of winter (March) and minimum during rainfall (August) every year. The sitting/walking tendency of birds with the plate inclination directly affects the PV output, which is demonstrated by optical study of glass samples (bird dropping patterns). Consequently, the studies of optical transmittance conclude the effect of dropping with different tilt regions I (β < 25°), II (25° ≤ β ≤ 60°), and III (60° ≤ β ≤ 90°), i.e., explained by bird movement onto the module surface. The result also showed that optimal inclination β (40°) has a smaller soiling effect in tilt region II (25-60°) correspondingly.
一个最关键的挑战是在拉贾斯坦邦西部的开放环境中，鸟类粪便沉积（污染）在光伏（PV）模块的玻璃表面上。本文现在专门强调关注鸟类粪便现象对 PV 系统性能的影响。本研究包括季节性鸟类粪便效应在不同倾斜角度配置下对能量产量减少的影响。考虑到这一点，在每年的冬季末（三月）观察到功率损耗最高，而在雨季（八月）最低。鸟类的栖息/行走倾向与平板倾斜直接影响光伏输出，这可以通过玻璃样本的光学研究（鸟类粪便模式）来证明。因此，光学透过率研究得出了不同倾斜区域 I（β<25°）、II（25°≤β≤60°）和 III（60°≤β≤90°）中粪便坠落的影响，即通过鸟类在模块表面上的运动来解释。结果还表明，在倾斜区域 II（25-60°）中，最佳倾斜β（40°）具有较小的污染效应。
