Speaking of sprinkler based . My next set of panels when i put them up . I am going to do a little research on cooling the panels . Run some type heat exchange under the panels with quick connects so if a panel goes bad so i can pre heat my water and keep the panel cool all at the same time . I have great access to solar edge panel monitoring so it will be a good way to experiment. I do have concerns though on leaks from the uv that may not be pretty and a total waist of usability.
