Again, your building department may require the foundation for a PV array to be designed by a structural engineer licensed in the state where the PV array is to be erected. This is required because failure of a PV array foundation may be a threat to the safety of nearby people. At a minimum, failure will result in costly damage to the PV modules. The foundation described here is suitable for most soil types, but no warranty of it's suitability for you soil or wind conditions is offered or implied.
If you are unable to dig holes of these dimensions because you encounter bed rock or if you have very loamy or loose sandy soil, (get the recommendation of a soil engineer or building department), then refer to the accompanying Chart for Flat Base Foundation for alternative foundation construction dimensions.
For type and size of pole to install in concrete foundation, refer to General Specialties Pole Height and Dimension chart. ———————————————————————————————————————————————————- General Specialties Recommendations for Pole Height and Dimension. CLICK HERE FOR PRINTABLE VERSION We can not guarantee a standard 1.67 safety factor if these recommendations are not observed. Since we can not assess each customer's individual site and conditions, a professional installer and the local building department should be consulted for the safest and most effective installation.
Footnote 1: There is not adequate clearance for these arrays with this size pipe. Use heavier schedule pipe or larger pipe diameter Footnote 2: For UPMs 12X HD, 15X and 18X, we do not recommend tilting past 60º without using the optional 90º Bracket Kit. This kit fastens the array to the pole below the tee top which is the safest and strongest possible attachment for the 90º vertical position. Most mounts do not need to be tilted past 70º unless they are in far north latitudes or in areas with extreme snow loads.
