Situational

Ground Mount Notes

AHJs require 10’ minimum distance around the array for maintaining a clear fire zone. Separate fencing is not required for the ground mount residential PV array, so long as the property is fully fenced. Ground Screws allowed with engineering. Freeze/thaw depth is 12”-24”. No grade requirements. If in a flood hazard zone then a geotechnical report and addition calcs by the Engineer shall be required. This may result in a minimum height above grade to keep the array out of the flood water height.
