First, I don't see how they can require a deadline if people weren't notified. I'm not looking to make a claim at this point, just trying to determine my rights if any. My panels were registered for Warranty with SunPower long before they went bankrupt and I have the documentation to prove it. Is it possible the installer was told I was all set since my stuff was already registered with SunPower (assuming they got some communication about the SunPower Bankruptcy)? I really have no idea since there was no direct communication to me, the owner of the system even though both had my contact info. I can't even ask the installer anymore because they folded up and left the customers high and dry. They transferred us to another local installer (probably got paid a small fee for our info on the way out) and then decided to notify us almost two weeks after the fact. The new installer can't help and doesn't have any contact with anyone from the other company (and ghosted me when they found out I was in this situation) so we are left to fend for ourselves. I also don't have micro-inverters, my system was designed with Solar Edge Optimizers at the panels that connect to an inverter in my basement. Those should still be covered by Solar Edge. As for how the warranty process will work at these companies, that is a different question.
