Ok, I’m just testing with your template and no equipment connected. I have copied your template. So i cant understand why i have 0% on all negative angles
I’ll leave it running for a few days to get a better understanding of the figures i think
Because if you look at the pictures of the original post you will see the panel can only go flat or it can go up. So the minimum tilt angle is something like 0 degrees. So 0 degrees is 0%, -10 degrees, -20, -30 are also 0% etc. It makes sense
