Hi Mac,

 

You can check out the unirac GFT which has a engineered ballast in their approved mounting designs.

Thanks Dana,

 

Normally I do a piered system for these, but I've got a project with a ground source heat pump loop at unknown depth under the array field.  I'm trying to avoid a puncture.

 

Thanks!

I have used Snapn’Rack’s system with grade beams. It uses a sched 40 - 1½” iron/galv pipe to achieve 90 MPH 3 sec micro burst rating for uplift. Please verify if this is still available from SnR.  I am pretty sure that we needed 18# of concrete/sqft of PV module. I would have your structural engineer verify this or whatever your local code calls for.

It’s a good system as long as you do not have frost heaving of the ground. I am not sure that I would do this in snow country unless your engineer could guaranty that there is a way to eliminate the frost heave. 

 

And if you are going to have to do that much ground prep why not use a pier or footing system?

Hello Wrenches,

 

Can anyone recommend a ballasted ground mount solution that is offered on a residential scale?  Below 10kW typically.

 

Thanks in advance!
