Lots of great solar panel info here. Getting ready to go with two Solar Bear panels. Had a question. Is it worth making the frame adjustable? My best March/September angle is 30 degrees, best April/Aug angle is 22 degrees. I don't really care about any shallower angle in mid summer, water will be plenty hot. It would be fairly easy to make an adjustable rack, but only adjusting what comes out to +6" at top and -6" at bottom seems like maybe not worth it. I think 30 degrees for ends of season probably makes more sense.
Also with Solar Bear going horizontally, I was planning on tilting East end up 6" so it would drain without having to blow it out. Just gets a little uglier since I'm putting them over my Pump pad rather than on roof.
