I'm going to go with a dark gray/charcoal standing seam metal roof. There will be zero mystery about long term performance of the roof system and PV system. PV mounting system will clamp to standing seam meaning zero roof penetrations. Panasonic HITT 96 cell panels with ultra low .26% annual degradation after 1st year. They gurantee 90% of rated power at year 25. I will pair them with IQ7X enphase micros so I can monitor individual panels AND no single point of failure. 25 year warranty on panels and inverters.
This setup will cost me about 5K more than my original Tesla contract but about 10-15k cheaper than the new pricing. If I wanted a power wall (I don't) it would be about a wash with new pricing and free power wall BUT I will sleepy soundly not wondering the long term consequences of this big financial decision.
