It helps to give the panels a wash,soft wash with powerwasher will do.
Oddly, it happened shortly after giving them a cleaning. Confused.
Are you selling power back to your power compan? They can change output digitally and that will slow it dow, if your not doing this you probably need to call your mfg for sure.
