[RE-wrenches] Use roof rock as Ballast for Solar Racking

[David Buckner]

Maybe RBI will know, Renusol was acquired by them.  https://www.power-technology.com/news/newsrbi-solar-signs-agreement-to-acquire-renusol-4284595/

  I believe they are history. Not sure if anyone has any product left. We did a project for a Marine base in Montgomery several years ago and they had those trays left over. Not sure who owns them now, will try and find out.

Has anyone used Renusol CS+ ballast racking?    I found them online and there is a picture showing the trays being filled with roof rocks like I am considering.  I am having trouble getting a hold of them.   I see that there is a post in the archives from 2011 for an older version Renusol CS60.    Anyone know of a contact or distributor for them?


Thanks!

I am surprised you can meet the required ballast needs for uplift consistently with the vagaries of simple rock, unless you are performing packaging and weighing of all replaced ballast.
I also see that none of the SolarDock web links work – are they still in business?

Hey Wrenchers,
I’m working on a ballast racking project that has a ballasted roof (river rocks on the roof).   The roof can not support the addition of cement blocks so I am planning to use the river rocks that are already on the roof as the solar ballast.    I have done this before using the SolarDock racking system as it fully encloses the ballast in a tray which keeps the rocks in place.

On the project I did about 6 yrs ago I hired a bunch of laborers to manually bag the rocks and it was quite labor intensive.    Has anyone done this using some kind of vacuum system?   I am hoping there is a better way.

Also - Any other racking suggestions other than SolarDock for this application?

I appreciate the feedback!
