Hi Wrenches, We typically use SunModo ground mounts with ground screws which we can put just about anywhere as our screw guy has a rock drill. We have one customer who is dead set on a top of pole mount array and will not settle for a typical ground mount with multiple posts. There is shallow ledge all over her property and we feel that digging multiple large holes to find one spot where we might be able to get deep enough would be a waste of time and resources. We have called an underground locator who uses ground penetrating radar and he scanned a few spots, but was unable to give us a good location based on soil types. What are you guys doing in this situation? Are there any alternatives, such as a pole mount with large base and ground screws? I hate saying it can't be done!
Thanks! Ben
