Well just to update you on the Solar on Sylken Sea, we anchor out or take moorings whenever possible, we boat mostly "off grid". After 10 seasons we have 4800 hrs on the Generator, so before solar we put 400-500 hrs a season on the Genny. By converting many appliances, lighting, TV/Entertainment Centre, water maker, refrigeration etc to 12V, now with our current 1200 W of solar last season we put 56 hrs on the Genny! The only time we run it is to heat water and do laundry. Plan to bump it up to 1800W and ad some water heating capability.
