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,...

Each panel also has its own Voc lying there in the sun. I don't understand how the voltage to be added just happens to be each panel's Vmp. Why that particular voltage?

so howinheck can each different panel be at its Vmp and you just add them up? It's magic!
The resultant 'amperage' would be determined by the diameter of the smallest orifice in the string. And, as long as your panels are reasonably close in Isc (diameter), it is magic.
