Solar panels require a controller between the panel and the battery to regulate voltage output; without a controller, a solar panel outputting 20-60 volts would overcharge a 12V or 24V battery that only wants 13.3V or 14.4V depending on its charge state.

“essential that you're going to have to have what's called a controller to control the solar output down to your batteries... your solar could be outputting 20 volts 40 volts 60 volts and your batteries don't want 60 volts”
