Shade effect on series panels.
Pictured below is the shading on 2 of 6 series-connected panels: And this is what the controller says: So, 57.2 x 5.6 = 320w (IN) Normal (full sun) should be about 84 x 7.5 = 630w,...

But why is each at the particular pressure it is at, and why are they all each's Vmp?
If it is not connected, it is at Voc. If it is connected, it is at the voltage of whatever it is connected to. With PWM, it is battery voltage. With MPPT it is the voltage the MPPT applies.
The MPPT can only apply one voltage but they are all at different voltages but their total voltage just happens to be the total of their rated Vmps. How did the MPPT figure that out?
I bet this has to do with those horrible watts things. :(
