Reply:Nice unit Zac.  You probably know this, but from the angle of the photos it looks like the bush in front may shade a portion of the lower panel.  As I understand it, ANY shading will reduce the output of that particular cell which affects the output of that entire panel.  If the one cell is shaded and only producing 50% of its' potential, then every other cell in that panel is restricted to 50% of the potential output.  I may be wrong, but that's how I understand the shading issues associated with solar panels.

Reply:Originally Posted by ZacThanks.  This group of panels is installed at a 60 degree angle and is optimized for winter production at my location.  I don't have any other space that is less shaded to put them so had to compromise on a location that that gets some shade, but is mostly unshaded in the winter since the nearby pomegranate bush is deciduous (loses leaves in winter).  (I have other panels that are mounted at about 40 degrees and produce plenty of power except in the winter.)The panels do have bypass diodes built into them that will reduce power yield loses when there is partial shading.  This allows the panel output to not be limited by shading on a single solar cell.What do you all think of my TIG welds?  (I didn't think they were very pretty, but hopefully are structurally sound.)
