Steve,
Best place to start would be the panel/coil manufacturer. They should have a complete installation guideline for said applications and wind ratings.

Would like to install snap lock roof panels of 1 x 6 v-joint pine roof decking. A 12' portion is over a covered patio with the bottom side of the roof decking exposed. This will limit the depth of the fastener to no more than 5/8". Is this acceptable, and if so what is the recommended fastener and spacing for roof clips? Design wind speed for this area is max 90 mph.
