    None of your voltages match. The solar panel produces only 0.5V. The battery produces only 3.7V and is charged from about 5V or 6V. The pump needs 6V.

    A battery charger does not dump power when the battery is fully charged. It simply turns off the charging.

    I noticed the same that the volts don't match.

    From my experience here are the best when it comes to quality and price for quick small run PCB prototypes:

    4PCB has a flat rate for up to 60 square inches of 2 Layer PCB for $33: http://www.4pcb.com/pcb-prototype-2-4-layer-boards-specials.html

    BasicPCB.com allows you to order 3 boards for 3 bucks a piece which is great if you're looking for cheap PCB prototypes.

    I'd recommend to stay away from offshore PCB houses like https://www.pcbway.com/ since they have gotten by boards delayed and also have had to pay custom fees on top of the delay.  Not to mention the quality of others like "dirty boards pcb".
