Solar Panel Wind Loads

Greetings All,

Im building a small solar farm and was hoping to find someone to double check my engineers wind load calcs. The panels are to be tilted at either 20 degrees or 30 degrees, they form continuous long rows, the highest point off the ground is 5 feet at 30 degree tilt and 3'8" at a 20 degree tilt, lowest point on both is 8" off the ground. The size of the panels is 8'6.375" by 43.3071", the are hung in portrait and are edge to edge continuous, except for a 5/16' gap. I'll try to upload a picture. we are only figuring wind loads on the PV frame cause we don't really get snow loads, and the panels only weigh ~140lbs ea, If anyone can figure wind loads on 3 of these panels (cause that's a section in between posts) laid edge to edge with a total measurement of 8'6.375" by 130.921" , with a total of 93.441 sq. ft, I would be thankful.

For the wind load his assistant was using 16lb per sq foot, but he used this same load for a 30degree tilt and a 20 degree tilt and I think the wind load should be less for a 20 degree tilt and calculated on the sq. ft profile presented to the wind and not the total square foot.

What do ya'll think?
