My Tesla team watches and maintains the solar roof without me having to do it too. Winter has been hard on production. Mine was so low it concerned them enough to make an appoinment to send a team to check on our equipment. It turns out that a north facing system is not very practical in winter. All the inverters and other equipment were operational but there was snow on the roof and only 16 degrees when they arrived. Obviously production was low.
Additionally they found that snow and ice were piled up where the roof meets the ground. One whole series is not producing. I am expecting production to soar once its spring. The sun will rise over the peak of the roof and the panels will get sun all day most days.
