Exporting to PVsyst automatically simplifies terrain and enhances the import speed

1. The problems of importing terrain without simplified Calculating the shade table in PVsyst is particularly slow. For example, when the number of terrain faces exceeds 200,000, it may take several hours. 2. Export the DAE and simplify it With the new version of Candela3D, you can Export *.dae files and Auto simplify mountains. 3. Why should the array be automatically elevated to a certain height Due to the simplification of terrain, some arrays may be embedded into the terrain, and PVsyst will report an error: the array penetrating with the terrain. If adjustments are made one by one according to the prompts, it is very time-consuming and may affect the simulation results. The entire array can be lifted a certain height, so that the mutual shading relationship between arrays remains unchanged. When the lifting height is small, the impact of terrain on the shading of the array is also minimal. 4. Improve the speed of…

Is the production slightly higher when arranged following the slope compared to the normal arrangement?

The author received a consultation: for a project in Guangxi, the yield (referring to the yield per kilowatt, the same below) of electricity generated by following the slope is surprisingly slightly higher than that when arranged directly facing south. After conducting Production calculations for two layout plans using Candela3D and PVsyst software, the Simulate results have verified the correctness of the conclusions. What exactly is the reason for that? The author has conducted an analysis on the actual terrain layout of the project, and the results are as follows: In the table above, the four normals highlighted in red account for nearly 70% of the total. Next, we will calculate the actual tilt and azimuth angles of the array for these four normals, using both due south and downslope arrangements, and employ PVsyst to compute the annual total radiation. It can be observed that for the aforementioned four orientations, when…
