I do not apply live load in the areas that the panels are concealing.

Subject: LL on roof with solar panels.

When you have flat panel solar panels on a roof, is there still a need to apply the roof live load to the supporting members?  I've always been taught that yes it would still be required but common sense says that since the solar panels are glass, it is unlikely that there will be any live load while the panels are in place.
 
All opinions are welcome.
