### Wind Lift on Solar Panel Plate
Individual solar panels have an aspect ratio of 1:2 (62.2 x 31.8 x 1.4 inches). The current plan for the five panels is to mount them side by side resulting in an aspect ratio of 1:2.56 (62.2 x 159 x 1.4 inches). F = 1/2 * p * v^2 * A* 2pi * sin(alpha); (p-density of air, v-wind speed, 2pi sin(a) - drag coefficient); density of 10 celsius air - 1.246 kg/m^3; <br>
solar panel dimension - 62.2 x 31.8 x 1.4 inches - 1.58m x 0.8m x 0.0355; area = 1.264 m^2<br>
__Lift on all five panels__: F = 0.5 * 1.246 kg/m^3 * (17.8 m/s)^2 * 1.264 m^2 * 5 = __1247.5 N__
