yes, another solar power question....26' c&c
26 feet, no cooler, just vhf, some interior lights etc, the outboard is a 9.9 with an alternator and electric start. The boat has 2 batteries. The marina that the boat will be staying at has NO shorepower. The boat will be only used on weekends. I like to listen to radio, either mp3, or XM, a little louder than average. What kind of solar panels, what capacity would you recommend?
