solar budget of 2700.00 Canadian
Hi all, I'm going to beef up my solar system. The budget is $2700.00 including installation costs. I'm considering these because I will be able to pick them up from Calgary and save the (conside...

If one panel is shaded it will still output current. But the shaded panel current is significantly less than the others. The diodes in the shaded panel will not conduct (the panel is producing power). Due to the series string, the shaded panel will significantly reduce total power production.
The parallel configuration will be much better.
Interesting. I think I understand...paraphrase.
If the cells are Partially shaded, they will be producing voltage/current, but less than all other series cells. However, their voltage/current Is sufficient to keep them connected in series, the diodes Don't bypass the weak cells. Therefor, the weak shaded cells act as a "hotspot" and series voltage/current flows Into the shaded cell in an attempt to equalize the voltage/current across the entire series of panels.
In series, the max current is the max conducted through the shaded cell; which is actually consuming power.
In parallel, all other cells/panels voltage/current flow through large diameter low resistance parallel wires, so the parasitic drag of a shaded cell is far less consequential.
