I make stuff with things
Hey peeps,
I have 20 t250 panels on make shift "ground mounts"... scrap lumber, rocks, laying on the ground. It's time to get them moved up to my rain collection roof for a variety of reasons - pv production, safety being the top two.
My rain roof is 20×30' and only about a 4-5 degree slope. There's ample room up there for 25 of these panels.
The roof is built over a 20' connex and two 2700g water tanks. There is no need to consider heat under the roof.
The roof is made from 12×3 ribbed aluminum roof panels on an over built treated lumber 2x6 structure with rafters 20" apart and perpendicular support for the panel. I have no concern for the roof supporting the roughly 820lb of panels.
I priced out laying unistrut rails and hardware for this project and it's going to run me about $1100 from Lowes... ouch.
My questions are...
1. In this case how much gap do you recommend between the roof panels and the pv panels?
2. Got any less expensive ideas?
