Introduction Due to the tendency of distributed photovoltaic power generation projects becoming more and more popular on the Internet, it is more and more important for the optimal design of various aspects of photovoltaic power generation projects. Based on a rooftop distributed PV power generation project in Shandong Province.
Method This paper optimized the design of bracket inclination, component arrangement and bracket foundation selection. Through PKPM modeling and calculation, the paper emphasized on material usage and economy.
Result The results show that when the concrete base weight is 2.4 m, the steel cost is 2.4 m, 2.8 m and 3.2 m, the total cost can be reduced by 0.55%, 27.5% and 37.9%.
Conclusion We demonstrate that the steel volume, the concrete dosage and the cost are all optimized when the distance between the two columns is 2.4 m.
