I have installed two strings of eight panels on a single story building. The top row of eight seem to be performing well. But the bottom string performs only about half to two thirds of the top.
Midday results yesterday which was sunny .......
String 1 240v and 1113w
String 2 261v and 493w
I'm not sure why the v are higher on string 2? Maybe a current issue?
There is some minor shade from a hedge early and late but not at midday. I have tested each of the eight panels this morning and each Voc and isc are much the same.
Advise would be very welcome.
Good job were not busy!
