Message Error for Detailed PV - Commercial

I am getting this error. I have googled and searched in the forum for answers but it seems that no one else is having this issue. I am using the 2021.12.2 SAM version. Could anyone please help me solving it? Thanks in advance

Hi Alejandro,

Could you attach a copy of a .sam file that demonstrates these results?

That error message indicates that the monthly albedo data has 1 value instead of 12 monthly values, which should not happen unless you use an LK script to change the value of the monthly albedo input. To fix the problem, you could try the following:

1. On the Location and Resource page, expand the Albedo - Sky Diffuse Model - Irradiance Data (Advanced) panel at the bottom of the page.

2. Clear the Use albedo from weather file if available check box.

3. Click Edit values for Monthly albedo.

4. Click OK to close the window.

5. Check Use albedo from weather file if available.

Best regards,
Paul.

Hi,
did you handle the issue finally?
