[RE-wrenches] BIPV for commercial

Perhaps another solution- using a roofing company to spray a layer of foam and then a silicone over that.
They offer a 20 year warranty.
You can first install your mounting equipment and they'll foam around them.
Its about 1" thick for the foam and 50mm-100mm for the silicone.

Costs about $5 sq ft.

Less expensive than hydrostop and it seems more effective.

Keep the single crystalline Marco! Enjoy the energy density......
 
Aloha, Keith

Subject: [RE-wrenches] BIPV for commercial
 

 
I have a client with a big commercial warehouse (metal-framed).
 
He needs to replace his metal roof and is asking whether I
know if any kind of reputable, listed product might work which would act as
both the roof membrane AND PV array.
 
That way the cost of re-roofing may be somewhat covered by tax
credits.
 
Anyone know of any such thing that might make sense for a 110
kW system?
 
Thanks,
marco
