I'm new to this group. If this topic is already discussed or open for discussion, please let me know., I have a unique situation. My roof is having very less space in East, West and South side so majority of the Tesla Solar panels have been installed on North side. Though I challenged the design, but I was told by the Proj Coordinator that Tesla panels will generate the power in North side as well with 75-80% efficiency. I live in San Ramon CA. MY PTO is pending with PGE. My question is to those who have solar panels in North, what is their experience?
