If anything was gonna get you it would probably not be sustained load, but rather any kind of gusting condition that might cause the 1250 pounds of collectors (educated guess, since I helped carry ten of them into my back yard) to start rocking. A couple of gusts that were close to the natural frequency of your array could cause sudden additional stress, above static wind loading. Does your modeling program have a way to account for such a condition?
Some guy wires (cables) strategically fastened from the top of your array to the mounting platform, or anchored to the ground, would be cheap, strong and prevent movement.
I think we all really want you to succeed.
