Hi there
I have a PV system with a battery and I keep getting the following error: exec fail(pvsamv1): Error calculating shading factor for subarray 0 at index 0.
I did not change anything under shading, I've left all values as default. I've seen a previous post about this and the error was in the weather file. I have checked the weather file and there are no errors with it. This error also started occurring on previous SAM PV models where I had no errors before.
It was suggested to me to try and use a previous version of SAM where I did not have this problem. The latest previous version available is the 2018 version, which I've installed. But now I cannot open any of my models as it was saved on the 2020 version.
How can I fix this? Is there a way to open files saved on the 2020 version in the 2018 version? Is there a new 2020 version coming out soon that fixes this problem?
Kind Regards
