I didn’t test tilted vs non but I can tell you that pic was taken in Soldotna AK around first week in June last year, around 1pm, with front of coach pointed east, so using the NOAA sun position calculator page (https://www.esrl.noaa.gov/gmd/grad/solcalc/azel.html) looks like suns elevation was about 50 degrees. I’m sure tilting the panels south that day improved efficiency quite a bit. I stayed at that campground for ~3 weeks it was the only time I tilted panels on my trip cause I just didn’t stay as long in one place after that and sun got higher in elevation as trip progressed into summer and I moved south toward Wash DC and back to AZ. Maybe this year I’ll do a same day/time tilt comparison with sun elevation data.
