[RE-wrenches] 40 Degree tilt array

[Dana Orzel]

One thing I have done with solar hot water racks to spread out the weight per connection point to the roof and to give the upper and lower connections a stable point to connect to instead of just the roofis to do a uni-strut type frame that is parallel with the roof and then attach the actual tilt rack to this parallel frame on the roof. It uses a bit more framing, but it also makes it super stable for Snow and snow retention or keeping snow from pushing up behind the panels
I have used both steel unit strut, and the aluminum unit strut that Sun Earth sells

Hello Wrenches,

Does anyone make 40 degree tilt up racking anymore. Unirac used to, and we have a 40 degree tilt Unirac system on our roof that works fine.

Unirac told me that the L-foot and rail attachments to the tilt legs are different now, and they can't go over 30 degrees.

Thank you,

Drake
