yes…the warmer it is,the better it heats….I can get excellent pricing on aquacal heat pumps….heres a page with heat pump info and also a heat exchanger which uses less amps-but I guess you probably do not care about that if you have electric solar: http://www.swimming-pool-information.com/pool-heat-pumps.html here is a page to help you pick the proper size heat pump: http://aquacal.com/heat-pump-information/heaters/pool-audit.html

I hope you are getting the largest solar system you can afford. I did, and am eternally grateful. As you can imagine, the cost per kW of generating capacity goes down as the size goes up.

For a heat pump, you could consider the type of system usually installed for ground source. Some of these depend on water from the ground, pumped through a heat exchanger. In your case, you could use the pool water., circulating it past the heat exchanger, and back to the pool. You could arrange it so the "waste" cold is sent outdoors when you don’t want to cool the house, and to the house on hot days. If there are winter periods when you do not want to heat the pool,, you could have the heat pump draw heat from the pool, for heating the house.

Of course you could use a resistance heater for the pool, but it would be two or three times less efficient. You can buy pretty huge inline spa heaters. They are on the Internet.

Solar can be used to heat a pool but a pool is a large volume and takes a long time to raise the temp. I would use the gas to raise the temp and then the solar to maintain. An auxilary electric heater would be expensive for that purpose.
You are in a excellent area for solar.
You might also collect heat from air conditioning since it is wasted.
