Getting solar modules onto the roof will be one of the most strenuous tasks of installation.
As modules are moving to higher power classes, we are seeing an increased size and weight of modules making the issue more prevalent.
When moving modules onto a roof, we suggest using a mechanical lift but recognise that it is not always possible nor convenient.
Many of our partners move modules with ladders and we recommend trying to distribute the force against the modules.
The optimal scenarios for module handling with ladders are to allow the module to rest against the arm, shoulder, back and head as much as possible to distribute the load away from a localised place.
