Javier,
Since the value you are watching won't change with the control decision, you don't need a controller with hysteresis. I would simply use an equation:
Glim = 1000
_On_Controller_ = GE(IncidentRadiation,Glim)
where the incident radiation is an input to the equation component.

It is simple, if the total radiation on the surface is below a Glim, I need the controller to output 1. If the total solar radiation is above Glim, set 0. The controller output will be used to divide a certain flow.
