Describe the bug

My weather file does not include an albedo column, but when I run a detailed PV simulation leaving the default "use albedo from weather file if available" option checked, I get an error.

To Reproduce

Steps to reproduce the behavior:

1. Create a new detailed PV model (no financial),
2. select my weather file that does not contain albedo values (it does happen to be a custom 1min interval weather file, see screenshot below),
3. hit simulate,
4. get an error that there are invalid albedo values (see screenshot below)

Expected behavior

I expected the "use albedo from weather file if available" option to not matter if the weather file does not include an albedo column.
