Anyone else have any advice?

We received a in-person quote on Sunday for both a San Juan and CPC pools.

Viking rep is coming out in a few weeks and we finally got in touch with a Blue Hawaiian contractor who should be scheduling an appointment with us today.

Anyone have any experience with using solar heating in the Mid-Atlantic region? I've been reading the threads on this board regarding them but everyone seems to live in warmer climates.

Thanks,
Bill
