Error Orientation #1: The shadings area is lower than the PV modules area

[Ben Gregory]

I'm new to this ....Does anyone know what this means please and how to change it?

Thanks!

[André Mermoud]

In the System part, you have defined modules which will require a given area.

In the 3D shading part, the area foreseen for this sub-array has not sufficiently area for placing all the PV modules defined in the system. Therefore there is a contradiction in you system design.

Thank you Andre.

Another question:

Is there a tool for working out the optimum spacing between rows of modules?

Thanks

Ben

[André Mermoud]

No, because there is no optimum: this is a multi-criteria and multi-variable problem.

See for example the article Optimization of row-arrangement in PV Systems, shading loss evaluations according to module positioning and connexions (A. Mermoud, EPVSEC 2012), on our site.
