I'm not sure the solar panels will keep the pool warm enough late Jan-Feb. Those winds can get pretty chilly.
I kept my pool at 98 for the winter with a gas heater. We turned off the waterfalls and kept a solar blanket on at all times when it wasn't in use. The first gas bill was tough but after the pool got up to temp the bills dropped considerably. I never turned the heat off. In the summer I keep it at 86. In the winter I think using that solar blanket is critical.
