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?

Solar panels and generators have at least two wires, one is the ground wire and one is the wire with hot wire. What is done is not that diffrent from electrons are lifted from the ground wire to the hot wires.
When something is connected to them and draws power they need to be both connected do the ground and hot wire. Electron passes through the device between the wires. You can’t just connect to one and get electrical energy out of them, you need a closed circuit.
So for the same reasons you need to connect to both poles of a battery, you need to connect to both sides of a solar panel or electrical generator.
This explanation uses DC and ignores that the power grid is AC. That elections are lifted up is not exactly correct but is an approximate idea of how works.
