We don’t just do RVs. We have created a solar panel kit specifically for charging batteries on boats. This kit comes with a 50W solar panel, marine rated charge controller and wire harness. This is ideal for electric trolling motors, downriggers or simply maintaining the starter battery. The 50W solar panel will produce about 12 amp-hours per day in summer weather.
