We decided to generate most of our power with Solar Panels. I know, it’s not something that makes a yacht necessarily looking prettier! Nevertheless, letting them run costs nothing and most important: they're silent and maintenance free. We should now generate enough power to keep the batteries full while on anchor without running a generator or the engine. It may not be 100% self sufficient when sailing as we need more juice for the autopilot and the navigation instruments. We have over 400 Watt in Panels – controlled by an MPPT Charge regulator.
