Heating Ideas

I am looking for some advice on ideas on how to heat our AGP pool this summer. With the stay-at-home order and strict regulations being imposed in Illinois it looks like my son won't be having a travel baseball season this year. Therefore, we be spending a lot more time in the pool this summer. Therefore I am looking for ideas on how to heat the pool this summer and gain some extra "swim time". Here is some background:

• Pool is a 27'x54" agp. 19,272 gallons of water
• We always use a solar cover at night
• Pool gets full sun from early morning to approximately 5 PM
• Running filter with a 1HP Hayward pump

From the research I've done it seems like a gas heater or heat pump will be out of our budget ($1,500+). Therefore I am leaning toward solar but have no idea where to put them. Here are some pictures of out set-up:

Any suggestions would be greatly appreciated!
