Solar and A Brief Encounter with Leafy Shade
Morning solar with a tree 40’ away. 3x250W series poly panels and 3 bypass diodes per panel. Past 7:50 AM the MPPT controller is decreasing the array voltage as it seeks the maximum power from the arr...

Maybe I'm confused on the issue
But I don't think the controller reduces array voltage
Yes voltage changes, but this is because of (2) factors
The panel warming up, and the load on the circuit
You can only get max voltage and max amps when the sun is directly on the panels,
The controller would love max voltage at max amps, so it could convert it to more amps
The voltage recorded , is the voltage the panels can sustain at that temperature with the amount of solar radiation being received
