These hinges are aluminum with a stainless steel hinge pin and would certainly have different thermal characteristics from the panels themselves. You can see the hinges at work as the panels unfold in this video of an array being deployed. Around 2:30 into the video there is a nice closeup. youtube.com/watch?v=XRXbi3sQKWc | |

In this case though it seems like a long way around to get a benefit that could be more easily obtained by keeping all strings in circuit in the first place! | |

Trying to understand the issues and what actually is going on with these systems - this gives more to think about so it's helpful. I don't know if array temperature changes induced electrically were meant to have some purpose, or if it were just an effect that could be seen in thermal imaging as just a way to illustrate an effect in an answer. | |
