The "tweaking" ended up costing me a couple thousand bucks. He had to replace the old, cheap quality wiring that the original, now out of business company, used, replaced three bad panels and now my system is making 26 kwh of electricity per day. The system runs backward during the summer (unless I use the AC) but I use WAY too much during the winter.I’m pretty sure she does. Had them cleaned & a solar guy to tweak them not too long ago.
