I built a 4-way tilting mechanism for a 235w module. A couple of other guys on the Forum led the way for me, Fire Instructor was one helpful guy. I can't seem to get the Forum search function to work for me but here's a picture:
Since I have an aluminum roof and wanted durability, I used three u-channels that serve as the basic mounts. Those are screwed and glued to the roof with 2" screws into the trusses. The center u-channel is unused for two mounting directions. The module rotates on 1/4" pins in two directions and is hinged to an aluminum angle piece that rotates in the other two directions. For hinges, I used stainless steel butt hinges. The struts are heavy wall aluminum box, 1" x 1/2", IIRC.
If I was going to do it again, I'd forgo the hinged direction and only use two directions. It is easy to orient my TT at home for storage and the module laid flat produces enough power for my needs, presently.
Edit: BTW, I bought the panel from Solar Blvd. They are good folks to work with. Somehow, the junction-> MC4 cables weren't included and a call to them had a pair of cables in my hand in a couple of days. I thought that spoke miles about their CS.
