Anyone in the Letsitele area near Tzaneen ? Vervet Monkey Foundation need help fixing their solar system which isn't charging the batteries. Need someone who knows their stuff to go and sort it out.
I have solar panels connected as 4 strings of 3 in series. If one of the 3 in series is covered by shade, will it be able to contribute to the charge, since surely the voltage will be less than the other strings even if it has bypass diodes.
