Going Solar need your help

[towney]

Ok, I have narrowed the field down to two companies. Placement of the panels would have to be on the West side of roof and north side, this is the best solution with respect to the sun. In the winter the sun is at the front of our home and the summer at the back. They both said max sf of paneles on the west side would be 300sf and 76sf on the north (not sure what this means though) with an average temp increase of 10-12 degrees, ideally they would have wanted 400-450sf. Ideally we'd like to extend our season into mid Nov. here in FL with a pool temp of 80 degrees. Of course we would purchase a solar cover (any suggestions on what is the best one) and keep it over the pool when not in use. Does anyone else have any other input or suggestions? Maybe a Heat Pump? Pros and Cons....


Solar design layout:

Pool has 430 sf surface area
Westside of roof~ (4) 1/2 4X10 1/2 panels and (3) 4X9 1/2 panels
Northside ~ (1 3/4) 4X10 1/2 panels

Total solar surface area of 376 sf.
