Thanks for that. Why do folk always raise the panels off the deck, base, roof before bolting down ? I've seen that several times before and i don't understand. A 3mm washer between frame and base would allow water to flow. Am i missing something ?
I looked into a few solar mounts and framing and with all the fittings needed for something like Unistrut it would be more expensive. I also liked the idea of using aluminum to get a lighter panel mount. Buying the aluminum in 25 foot lengths of 1/8 inch thick 1 inch angle was about $15 and 1 1/2 inch angle about $24. I didn't really keep track of how much I used for the panel mount.
The idea of angling the pv panels will definitely improve performance; the spacing of the rows makes sense for shadows; but to not consult a structural engineer for the design makes this design REALLY REALLY BAD choice. Building codes around the world will usually require roofs to be able to sustain 40% more capacity to lifting forces from wind than maximum combined snow, ice and wind loads downwards. So the chances of this array setup being torn off the roof leaving gaping holes is highly likely. This design needs to be validated by a structural engineer.
I didn't realize the lifting forces were that high, maybe I will have to add some hurricane ties where the roof joists attach to the beams to minimize that possibility. Thanks for the comment.
Great set up👏🏾👏🏾
Thanks!
this is really nice!
Impressive 👏👏👏
Thanks of great help.

What was the black stuff to stop the water going through?
Cool
Is 3:19 silicone or cement glue?
any leaks in the roof?
Why would you use such small panels?
How expensive was all that aluminum angle stock? Why didn't you use Unistrut or Superstrut?

Nice design, but if an earthquake strikes it will all be crushed. You should have consulted a seismic engineer before constructing this.
Thanks for the idea, but where this was installed is not a seismic prone area.
@@planbuildplay8528 I was trying to be funny. Your design is great

Maybe add some metal on the back to stop the wind lifting the panels?
