When the kids were younger and I was acting as temporary housing at sailing school for 2 weeks and not moving off anchor, one 50 watt panel changed the situation from 30-60 minutes of engine per day to 30-60 minutes every other or third day ☺ Joe

I am also considerably further south in the middle of the Chesapeake Bay. I have an Gensun MPPT-boost charge controller for each of the 2 panels. They are rated for a 105w panel but I think based on the angle of the solar impact and inefficiency of flexible panels I could have gotten away with 120w panels. Experience has shown that I can plan on about 50 Amp-hrs per circuit per day. 100 AHr per day into my 450 AHr flooded lead acid battery bank. The system has worked perfectly fine over this summer when I have had to abandon the boat away from shore power for more than 3 months. It really is not handling a big load. Nothing but the bilge pump. Every time I get on board I do check the battery voltage and it is always fully charged. I'm not sure that the solar is sufficient for running comms, navigation systems, lights, and fridge... Let alone just a fridge on a long term basis. My cruising habits include motoring into and out of port so the 100 amp alternator makes short work of topping up the batteries morning and night. Happy to answer any other questions you may have.
