Hot Water panel sizing 63sqft

I'm building a currently off grid week end cabin. Currently there's nothing there, no water, no power, no structure. Sturcture will be
about 600 sqft living with rain water collection before I go all in with a well.
I'm meeting a guy today with (3) used 7'x3' hot water panels, $80 each. He's been heating his water with 2 similiar panels in a tanked system without issue for 15 yrs. I will definatley buy 2 for my cabin. I will most likely use a solar powered pump to circulate to an 80 gallon electric hot water tank.

The 3rd panel...I will most likely buy, but what would be the best use for it?
I could tie it in with the other 3 for lots of hot water and possible make enough heat for floor or a radiant coil. We have mild and mostly sunny winters. Other heating options will be wood stove and generator powered minisplits. Since the cabin will only be occupied on weekends I can probably average enough heat through the week to keep it comfortable from October through March.
