Hi wrenches, I used to do these kind of calcs all the time but am wicked rusty. What assumptions do you use for future (degraded) hot temp Vmp of a PV string to check if you will still be able to operate inside a given MPPT range? Specifically interested in assumed yearly degradation to Vmp, assumed actual operating cell temp, and if it is appropriate to use STC value as the starting point and if not what would be better (NOCT?)
Thanks, -Nathan
