Index Out of Range Error

If you see the error message below, it pertains to the size of your roof area:

Roof_Size_Error.PNG

 

PVCAD calculates the wind zones of all roof areas created. If the area of the roof is too small, the wind zone calculation cannot compute correctly.

Check your units and/or scale and make sure the roof is representing the actual size of the roof intended. Once the roof is scaled and drawn correctly, this error should not appear anymore.
