Today I installed two 160 watt solar panels and a PWM charge controller on a 2014 Thor Miramar 34.2 Class A motorhome. The best part of this job was the excellent surf rolling in. The San Elijo State Beach Campground is near Cardiff by the Sea and many of the spots are on a bluff overlooking the Pacific Ocean. You can run your generator but only during the day. There is no power at these sites so having a solar system to keep the batteries charged is the only way to go.
Today I started working on troubleshooting the solar system on a Southern Cross 39' Sailboat. The boat is docked at a slip on Harbor Island in San Diego Bay. The owner is getting his boat ready for full-time living and requires a solar charging system that will keep his batteries charged while at sea and anchored. Having a boat slip with electricity is not always going to be an option.
