Athicha Posted March 28, 2019 Share Posted March 28, 2019 (edited) Hi everyone,I am working for shading loss simulation for PV plant.So, my plant layout is far from mountain around 270 m. , details as below picturehttps://drive.google.com/file/d/1gbq0jGIvK_elccKFOKBPeRJBeAhTq-3E/view?usp=sharingI would like to know , what option is suitable to calculate shading for this case , Far shading for Near shading ?And if it need to calculate near shading loss option , how can i create the mountain shape as shading object in 3D construction in PVsyst?Thank you in advance!

André Mermoud Posted April 17, 2019 Share Posted April 17, 2019 The thumb rule is to consider a shading object as "Far shading" when it is at a distance of at least ten times the sizes of your PV system. So if your PVsystem has a size (width or length) less than 27 meter, you can indeed use the "Far shadings". In the opposite case, you can create a ground object for simulating your mountain. Don't define a too detailed grid as the calculation time may become prohibitive. Don't forget to check the option " Enable shadow casting" in the object's properties.
