This panel is large enough to handle the average sailor's use on a boat up to about 27 feet. And the controller prevents overcharging during those periods when you just aren't able to get to the boat as often as you might like. The only problem we have with this installation is it is so trouble free that owners often forget about it completely. It is still necessary to check the electrolyte level occasionally!

1) Given the rapidly changing solar panel market, the panel you receive is likely to look different in some way than the panel pictured. It may be a slightly different size or the cell layout may be different for example. What remains the same is its rigid design with a robust aluminum frame and brackets for pulpit mounting.
