Basically there are solar collectors which collect the sun
rays. They are in concave shape, flat etc. Solar cells convert
Solar energy into Electrical energy. They are silicon coated
cells. They work on photo electric effect. when light falls
on the cells, valence electrons are liberated by absorbing the
light energy. These electrons start circulating & form
Electricity.

How do I know if a transformer is saturated? I am doing the simulation of the saturation of a transformer, but what parameter tells me when a transformer is saturated? How do you calculate? is on the plate?, there is a rule that can help me? How could model? I understand the saturation occurs when the flow can no longer bind to the other winding, this is given to certain current, this current is the same that appears as the highest in the bale of features? Thank you for your help Eduardo Alvarez Guatemala
