Solar energy is one of the promising renewable energy sources which has the potential to meet the future energy demand around the world. To maximize the irradiance fall, solar panels are generally equipped with a motor tracking system and are placed at a specific tilt angle. However, tracking methods are not cost‐effective and a fixed tilt angle is not productive. This study proposes a method for harnessing maximum output from photovoltaic (PV) panels throughout the year by determining the optimal tilt angle. The investigation is performed on real‐time solar PV panels of 5 kWp rated capacity installed at 10°, 20°, 25°, 30°, and 40° angle on the rooftop of engineering institute situated at Chandigarh, India. The real‐time power generation response for a year is used to find the optimal tilt angle. The results obtained from the practical setup are validated by comparing it with the simulation results of the regression analysis. In addition, the impact of the optimal angle on total power generation and carbon emissions is analyzed. The results reveal that the proposed approach is quite effective to increase the power generation of PV panels up to 7–8% and can be practically implemented in any location throughout the world.

使用实时数据采集确定光伏电池板的最佳倾斜角度。



太阳能是一种有前景的可再生能源,有潜力满足世界各地未来的能源需求。为了最大限度地降低辐照度,太阳能电池板通常配备电机跟踪系统,并以特定的倾斜角度放置。然而,跟踪方法不具有成本效益,并且固定倾斜角度效率低下。这项研究提出了一种通过确定最佳倾斜角度来全年利用光伏(PV)面板最大输出的方法。该研究针对印度昌迪加尔工程学院屋顶上以 10°、20°、25°、30° 和 40° 角度安装的额定容量 5 kWp 的实时太阳能光伏板进行。利用一年的实时发电响应来寻找最佳倾斜角度。通过与回归分析的模拟结果进行比较,验证了从实际设置获得的结果。此外,还分析了最佳角度对总发电量和碳排放的影响。结果表明,所提出的方法非常有效地将光伏电池板的发电量提高了 7-8%,并且可以在世界各地实际实施。
