Need a little extra now. I've had another solar rep come to give their opinion and what I'm getting is max panels is 7 where 12 is needed. He put his honest opinion forward and said the best resuls to heat the pool would be a heat pump. Suggesting a Aquatherm 114K BTU. Now he mostly does solar with heat pumps secondary, so I'm thinking he's giving an honest opinion. Any thoughts on a heat pump vs solar. I know a heat pump will have an operating cost but I'll get more then a 8-9 degree increase with solar. Thanks
