I was also able to borrow a Solar Pathfinder.
The solar access at the garage is pretty good. Not perfect, but pretty good. As you could see from the time lapse video I already shot, there's a little shading at these very short days of the year.
I was only able to set up the solar pathfinder on the ground right at the base of the garage. The roof is covered with snow, and I didn't have any good way of doing the pathfinder actually on the roof. I'll to a Solar Pathfinder trace again sometime when it's reasonably safe and accessible.
