The installation on the system was good. They had some wiring issues in the inverters when they first installed the meters, but that was quickly resolved. We had the panels installed on my barn-style garage because the roof on our old house will probably need replacing in <10 yrs. The garage was built in November. The second pitch on the barn style roof is pretty steep, so there isn't very much snow accumulation on that side. The panels actually seem to catch the snow and just melts instead of coming down in slabs. Rain hits the gutters properly AFAIK. They put squirrel resistant mesh between the panels and the roof to prevent critters from getting behind the panels to chew them up.
I don't have a current picture, but this is one my wife took during the install in April:
For reference, the picture is facing east. There is a set of panels on the top east pitch that cannot be seen from this angle.
