I understand that things like solar panels and wind power charge up electrons to generate power but how did noncharged electrons get back to the cell? What am I missing?

They do not. The panel moves electrons from one wire to another. Besides this movement no charging takes place.
In a box nearby, those electrons flow through the box and back to the original wire. That loop is all of the moving that they do.
In another set of wires, there is a pushing and pulling of electrons from the box. The same idea except the direction repeatedly changes. Several of these loops, with boxes between, run between the power station and your home. Your home even bas several of these loops, with a pushing and pulling between the wires. That is what moves the energy.
