I need to find where/how to design a system that uses solar cells to replenish a battery. So that as the battery is being used up the solar cells recharge them or others at the same time.

I also need to figure out where to buy small cylinder air systems (pneumatic pistons) connected to a 20oz simple air source so when pushing or pressing something they push out and return. electrically or mechanically

If you leave a solar panel connected to batteries while the batteries are being used, they already contribute to the output power and hence cause less current to be drawn from the battery.
So, it is quite normal for the solar panels to do this and it means their power is not being wasted.

No idea about the pistons. Maybe try Mechanical engineering.
