There is no project to send. This bug is in the Heterogeneous Arrays Tool, as the subject line indicates.

For example, use the following settings:

Array nb 1

Mfr: Trina Solar

PAN: Trina_TSM_305_P14A.PAN

Nb modules in Series: 2 (This is the ONLY one that really matters)

In parallel: 1

Plane Tilt: 30

Azimuth: 0

Albedo: 0.20
