Too many holes in solar panel frame?
My bad. Changed the design of PV mounts after had already drilled holes in the frame. So the panel is a lot lighter now, and plenty of ventilation :)... Big panel, 60x40", 40 lbs. I can see how it fle...

Thanks, then it will be just a caulk. Some holes are in the sides, not in the bottom, and sides of the frame are double-wall, i.e. when water gets inside it stays inside until drains out through the drain holes.
Well, I spent so far only what 500W and controller cost me. About a half or one third of a generator cost. Since the planned use of the rig is south of the border, this should work for me. It works already, my power needs are very moderate.
Flex will be dealt with - TAD - by adding the 3rd tilt leg in the middle of 5-foot side of the panel. Have to do this anyway as many anchor screws are in the plywood, not rafters, and desert winds can be cruel.
Wooden tray - interesting. Need to think. Though this will only help with the flex (which will be helped with by the 3rd leg already). I think it wouldn't help with anchoring the tilt legs to the roof, or would even make it more complicated. Maybe one horizontal board, between the corner tilt legs. BFL, any pics of that tray in use? I know it's winter now in BC, but may be from the last summer?
