A single solar panel is going to charge your batteries much too slowly you ll use up the stored electricity faster than the solar panel can charge them again. Alternatively you can purchase a solar generator with the amount of watts you need. Batteries are designed to produce a specific voltage and they are rated for a certain number of amp hours.
