Any experts here ? I'm curious as to the pattern...
My 2y old system (warrantied) started producing 30-40% max of normal output... There's a pretty obvious cutoff on the graph where one day to the next the bar is 30% of normal (similar sun exposure), so I don't imagine it's dirty panels (I cleaned them anyway). If I was guessing it would seem 1/2 the panels would have disconnected but that seems impossible, it's not like a loose plug. Are inverters knows to fail that way ? Delivering less than 1/2 the juice ? I would have thought the thing would work or die completely...

About to find out how good the service is, and what they do for my bill while the system is not making $ for me. Ugh. Also less than impressed with the monitoring. I spotted the issue, called, and then and only then did the system display "underproduction issue being monitored" LOL. I'm the sensor apparently. All in all I'd buy a smaller system cash, instead of leasing a big one like I did, in hindsight.
