What Is The Difference in Power Generation Between Photovoltaic Modules With Different Orientations?

The solar radiation received by photovoltaic modules with different orientations will vary, so the power generation of photovoltaic systems is closely related to the orientation of photovoltaic modules. According to data, taking the area between 35 ° and 40 ° north latitude as an example, the irradiance received by roofs with different orientations and azimuth angles varies. Assuming that the power generation of the south facing roof is 100, the power generation of the east and west facing roofs is about 80, and the difference in power generation can reach about 20%. As the angle shifts from the south to the east and west sides, the power generation will show a decreasing trend.

Generally speaking, the power generation efficiency of the system is highest under the conditions of due south orientation and optimal inclination angle in the northern hemisphere. However, in practical applications, especially in distributed photovoltaics, due to the limitations of building layout conditions and scene area, photovoltaic modules often cannot be installed in the best orientation and inclination angle. Multi orientation of modules has become one of the pain points in the power generation of distributed rooftop photovoltaic systems. Therefore, how to avoid the loss of power generation caused by multiple orientations has become one of the trends in photovoltaic product technology research.
In ground photovoltaic scenarios, the tracking range of the Kesheng Zhiguang KST series tracking photovoltaic bracket system can reach ± 60 °! Can maintain photovoltaic modules at the optimal tilt angle for a long period of time for power generation. The Kesheng Zhiguang KST photovoltaic tracking system adopts "astronomical algorithm+closed-loop control" and "AI algorithm" to achieve intelligent tracking of the system and maximize the power generation of the photovoltaic power station system. Compared to traditional fixed bracket systems, the power generation can be increased by 15-30%.
