Woo-hoo! Scored two 40 watt panels at the Miami Boat Show. That will give me a total of 120 Watts when I install them along with my current 2 x 20 watts. Now my question. I'm not an electrical guru. Is this an adequate amount of wattage to charge me batteries while on the hook? We traditionally don't use a whole lot of juice while on the hook especially since I've converted to all LED interior and nav lights. I guess our biggest draw is either our fans or TV.
