I have had my system operating for approx 2 years, 17 Sunpower 345 panels and it has been great. I noticed the last month on a good day, the power graph flat lines at approx 4.9 and then stays there for approx 1.5 hours during peak hours. What is strange is for the last 2 years I always got a full bell curve with no "clipping" and a max. output of approx 5.3. I can only see the aggregate output and not the individual panels/micro inverters, I called my installer and at first they did not understand but I think I convinced them something has changed. I think I understand clipping but why after 2 years and is it more possible-one or two panels or micro inverters are having issues? I know it is minor when i look at output loss but would still like to understand what happened?
