Abstract: A system of mounting a plurality of arrays of photovoltaic devices includes a plurality of columns, a first array of photovoltaic devices arranged on a first platform, and a second array of photovoltaic devices arranged on a second platform. An upper edge of the first platform and an upper edge of the second platform are horizontally spaced-apart and each are vertically spaced-apart from the ground surface. A lower edge of the first platform and a lower edge of the second platform are horizontally spaced-apart and each is vertically spaced-apart from the ground surface. The second array of photovoltaic devices is arranged on the second platform a predetermined distance from the lower edge thereof which corresponds to a level of shading caused by the sun impacting the upper edge of the first platform to provide a maintenance area to access the second array of photovoltaic devices.
