Shading area is more then area for solar panels

[Mixey]

Dear Sirs!

Could you explain me how program PV Syst calculate:

- shading from nearest string of solar panels,

- optimal distance between strings.

My problem is: program shows me that shading area is more then area for solar panels, what shall I do in this case?

Thank you.

The shading calculation is a geometrical calculation as function of the sun's position.

The program doesn't calculate the optimal distance between strings, as there is no optimal distance. This is a multi-variable and multi-criteria choice. It depends what you want to optimize.

The warning you are talking about has nothing to do with these questions: after defining the 3D scene, PVsyst checks the compatibility between your specification of a number of modules (in the "System" part), and the area you have defined in the 3D scene. If you have defined a significantly too big area, or an insufficient area, PVsyst will warn you.

Hi Andre,

I've been struggling with the same problem and thought that maybe you can help.

My question is that If the program doesn't calculate the optimal distance between strings then is there any way to do it. If not, then what are the alternatives for it.
