Background technique

At present, photovoltaic power generation is a common form of solar energy utilization, and photovoltaic tracking system is an effective way to effectively increase power generation and reduce the cost of photovoltaic power generation. Conventional photovoltaic tracking systems mainly include: photovoltaic modules, tracking bracket systems, tracking controllers, inverters, etc. Most of the photovoltaic modules are installed in a flat manner, and the installed capacity of the system on a single surface area is not large, and the power generation of the system is relatively low; On the one hand, in addition to direct light, the sunlight reaching the earth contains abundant scattered light, especially in low-light environments. The data show that even in sunny plateau areas, scattered light still accounts for 10-20%, and the total annual scattered light in the southern region accounts for 50-70% of the total light. However, the role of scattered light has been ignored. Therefore, the use of scattered light has a positive effect on increasing the power generation of the system and reducing the cost of power generation. the

Breaking the existing flat installation form of photovoltaic modules, on the premise of ensuring that the modules receive direct light efficiently, it is possible to make full use of scattered light, increase the installed capacity of the system per unit area, and adopt a more reasonable installation structure. the
