Which of the following tests measures axial uplift when performing load testing of driven-pile foundation members

A rooftop PV system is being installed on a residential building with a 30-degree tilt angle. The modules are oriented directly south in a location where the solar noon altitude on December 21st is 30 degrees. What is the minimum distance required between two rows of modules to avoid shading between 9 AM and 3 PM solar time, assuming the module height is 3 feet?
