Ask a Renewable Energy Expert

I am helping a non-profit retirement village to develop a ground mount solar array to reduce electricity costs. Because a large portion of the land is situated on a former landfill (largely construction materials) the solar panel support structure may be more expensive than standard mounts. I am looking at types of ground mount systems available and came across PowerRack by Powerfield Energy (PowerField Energy - Easy & Affordable Solar)   . Does anyone have any experience with this system or any other system that might be suitable for this land? A geotechnical engineering study was done on the property in 2006 and their recommendation was that the land is not suitable for building homes or apartments.
