Abstract

This paper presented an area filling algorithm for automatic layout of photovoltaic power stations and a ray detection algorithm for shadow analysis. The functions of PV modules automatic layout and hourly shadow analysis were implemented on Sketchup platform based on BIM technology, and then the results can be compared with actual PV power stations. The results showed that the automatic layout and the shadow analysis algorithms were in line with actual application of PV power stations. Compared with traditional PV station performance simulation methods, the visual degree of the presented work has a significant improvement. In addition, based on the measured meteorological data the difference between the simulated annual power generation and the actual power generation is about 1.5%, which indicates a certain accuracy of the proposed method.
