Hi all,
I'm finally getting a solar system together and need to build a rack to hold the panels.
The panels are quite large (48"x42", 40lbs each) and I want to mount 2 side-by-side on a ground mounted rack, which would be adjustable for tilt.
One area of concern I have is the amount of wind we get (yes, a windmill is the next project), greater than 60 mph is not uncommon. I am worried about the panels catching the wind and breaking the mount.
My basic idea is a pair of 2x6's forming the sides of the rack, with aluminum angle run across the sides to hold the panel. The 2x6's would be further braced on the reverse with a diagonal piece of angle.
The tilt adjustment would be with concentric square tubing, with through bolts for making the adjustments. The four feet would be hinged with some large angle and J-bolted onto sono-tube concrete footings.
I thought about doing the whole lot in aluminum, however this would be quite expensive and the design would be more complicated to use the angle (lots more junctions needed).
With 2x6 I can cut a small grove to take the angle and bolt through the flat into the edge of the 2x6.
I'll attempt to attach as quick sketch of what I mean.... any comments?
Simon.
