[RE-wrenches] ballasted ground mounts residential scale

[Jeff Clearwater]

I mispoke:

"This might expand small system options for those manufacturers only 
offering ballast systems to large system buyers."

What I meant to say is utilizing concrete grade beams as foundations for 
existing residential and small commerical ground mount solutions could 
expand the options that we installers have for ground mount solutions 
since most offerings for pre-engineered solutions are intended for the 
utility scale market.
