It is unlikely that water running from the face of the panels will create erosion under the <br />bottom edge of the lower panels. The panels are set one-half inch apart to allow some of the <br />runoff to drip to the sides. Water dripping from the bottom edge tends to disperse somewhat <br />by wind action. Solar operators do not want erosion under the panels, as that could create <br />minor problems. <br />Solar Energy Conversion Panels <br />The solar energy conversion panels will be single -axis trackers, which tilt up and down to <br />follow the sun during the year but not during the day or a fixed tilt system that faces south and <br />does not move. They will be approximately 12 feet tall and arranged in arrays as illustrated <br />below. There would be approximately 4,000 individual solar panels. <br />Figure 6: Typical Solar Arrays <br />Figure 7: Appearance of Typical Solar Panel Arrays in a Field <br />The panels will be mounted on a steel and aluminum racking structure and average <br />approximately 12 feet above grade when in their most upright position. <br />The racking system is installed in the ground with pilings (I -beams) that are driven directly <br />into the group at a depth usually between 6 feet and 8 feet depending on soil conditions. <br />315 Manitoba Avenue, Suite 200, Wayzata, MN 55391 <br />
