Accounting for Solar Panels on Roof | Eng-Tips
In essence, when checking global effects, I would just ignore the solar panels and consider the roof live load. The information about the concentrated load helps.
Dead loads remain constant, including panels, mounting racks, and hardware. This weight persists continuously. This analysis verifies the structural integrity of your building, preventing potential da...

Is the photovoltaic panel counterweight considered a constant load - PROTON POWER [PDF]
In essence, when checking global effects, I would just ignore the solar panels and consider the roof live load. The information about the concentrated load helps.
Structural load analysis is not an optional expense; it is a fundamental part of a safe, compliant, and durable solar energy system. It
The weight of photovoltaic panel systems, their support system, and ballast shall be considered as dead load.
This weight is a permanent addition to the building''s dead load, which must be safely accounted for alongside temporary environmental forces like wind and snow.
Engineers must evaluate whether existing structures can support total system weight plus environmental forces, or if reinforcements are necessary before installation.
It''s not a load that will come and go to be considered a live load. If that''s what ASCE explicitly says than it seems like you are kind of stuck with it. Yeah but I don''t think you should count a live load
ASCE 7-22 specifies that "solar panels shall not be considered as part of the load path that resists the interconnection force unless panels have been evaluated or tested."
A dead load refers to the weight of the panels and mounting equipment that remains constant over the life of the solar installation. Several factors need to be considered
The self-weight of the photovoltaic panels and modules and ballast (if any) shall be treated as dead load. Roof Live load shall be determined per section 1607 of the OSSC.
When available, the design roof live load of the existing roof structure may be utilized, in part, to support the new PV system dead, earthquake, and wind loads. Concentrated loads applied to existing roof
