Re: Solar power ~ no more running the engine
The wife and I did for a couple years living on the hook in the caribbean (the Virgins / Puerto Rico area).
We had IIRC 320 watts in two panels with the appropriate smart charger/controller feeding a bank of 8 T105 batteries. I did have to use the engine to bring the batteries back up once during hurricane season but it was after 5-6 continuous days of heavy rain and no sun. Other than that one time we were fully solar powered.
The saving grace with us was our lack of refrigeration so didn't have to budget that into our needs power wise. We powered a laptop or two, halogen cabin lights 2-3 at a time (at night), deck lights, stereo, GPS/Radio/Chartplotter, water pump, bilge pump(s), occasional windless use, occasional SSB use, about 1 hour a day watermaker use. This was on a Ohlson 38 FWIW.
