ground Mounting system Pile driver-screw base-Solar support structure

How is the Screw base to be put into the soil, with the pile driver, there will be much easier.Dig a small hole to put the screw straightly , and then with machine power to put into deeper soil.
Screw base makes the ground mounting easier to be installed.
