A method for “double cropping”, with photovoltaic panel arrays mounted on and operating from specialized photovoltaic solar array support structures that are supported above agricultural fields at heights that allow the passage of large mechanized farm equipment to pass beneath. The method of operation is optimized for sun sharing operation in that the solar array support structure and the solar panel array thereon is designed, spaced and computer positioned so as to optimize both the generation of electricity and the agricultural efficiency of the underlying land.
