Bill, is your insurance paying for the new mast?
As far as your solar panels go, our experience with our system has exceeded expectations.
We have two large 235-watt panels on our roof, and 6 Fireflys for our house bank. And a Victron 3000-watt controller/inverter.
The beauty of the Fireflys is that we can run them down to 20% safely, so it takes fewer Fireflys, compared to lead & AGM, to achieve the same power availablity. Plus, they charge faster than lead & AGM.
We run a small electric ceramic heater at night and still have 25% left in the bank in the morning to make coffee and start the engines. This is on top of keeping our 10.6 cu ft fridge & freezer happily humming along. By mid-day the bank is fully charged again, even on partly cloudy days.
If we ever buy another boat, we'd install something similar.
I've been so impressed by our boat solar I am thinking about converting half our house to solar. The only thing we need the grid for is the a/c; we have natural gas for the stove, hot water and furnace in the house.
In other words, solar is awesome on the boat. I'd recommend keeping it.
Cheers,
Mrs. Trombley
