Material cost for ballasted roof mount system

[electrofelon]

Anyone have any ballpark numbers $/KW
for ballasted racking? I've installed megawatts of it (mostly panel claw), but never involved in the numbers end. Got a client who says he wants PV on all his roofs.

Depends on what manufacturer ballasted system you use ,degree required to be tilt and the spacing desired, usually Unirac iron ridge ,DPW or any racking manufacturer has the estimation tool in their web site.
you just have to design the system , they will give you all the BOM with price, the ballast blocks are separate costs though that's different from racking.

I also talked to a friend of mine who has been involved with that aspect of ballasted solar,. And he said CED offers a service where they will (presumably) analyze the site via aerial photos and make you up a bill of material and even provide the ballast details.
