On my 2004 Hunter 386, I installed a Kyocera 130 watt solar panel. Advertised to produce 7.39 amps/hour on a good sunny day, that gives me approximately 35 amps per day. I built the support structure over the bimini and attached it to the SS arch on the forward side and two uprights from the aft seat rails. It took 40 ft of 8 AWG wire which I ran from the panels junction box, then down inside the SS tubing, then out again into a watertight seal leading inside the port lazzerette. I snaked the wire along the port side and terminated it under the nav table which has a removable panel. At this point I installed a 15amp breaker then ran the wire into a Xantrex C35 charge controller. From there the wire was connected to the house battery post feeding the battery switch ON position. I can use either the breaker or the battery switch to disconnect the solar panel if I have maintenance to do. The C35 has adjustable bulk and float setting and with my Xantrex Link 20 battery monitor I know exactly whats happening to my batteries. I also installed a Xantrex battery temperture module on the house battery so the controller can provide proper voltage as the seasons (temperatures) change. I also installed a Xantrex Echo-Charger, so excess power generated by the panel, but not needed by the house battery can be sent to the starter battery. This arrangement is keeping both batteries fully charged, and while on the hook for a few days, I have adequate power to keep me happy. I went with solar as, the Hunter 386 doesnt have much room for a gen-set - which also requires maintenance and makes noise, and a wind generator just doesnt look good on a sailboat (my opinion). This is a great project if you have the time and energy to do it.
