Matthew,
I do not have a current copy of the NFPA Life Safety Code, but I recall 
that it references the ASCE 7.

Per ASCE 7
Dead loads consist of the weight of all materials of construction 
incorporated into the building including, but not limited to, walls, 
floors, roofs, ceilings, stairways, built-in partitions, finishes, 
cladding, and other similarly incorporated architectural and structural 
items, and fixed service equipment including the weight of cranes.

ROOF LIVE LOAD: A load on a roof produced
(1) during maintenance by workers, equipment, and materials and (2) during 
the life of the structure by movable objects, such as planters or other 
similar small decorative appurtenances that are not occupancy related.

If it is "fixed" it is a dead load and should not be counted as live load.
As an extreme example, if the solar panels weighed 20 psf, and your roof LL 
 is 20 psf, you have zero capacity for the maintenance workers.
