That gets us somewhere around end of November early December.
That’s it. Rooftop solar - for maintaining pool temp - is useless until end of feb-March.
Yes - 3 months with no pool access. That’s not a problem for us as the house also came with a hot tub. We fire that up from nov thru feb then shut it down when the pool is back in play.

The OP has issues with no heat during the exact time you mention above. It's great that you don't use your pool during that time, but if the OP is a snowbird, he is not able to use his pool for the majority of his time down here.
Everything you described is exactly what I would expect - works great when you don't need it, sort of OK when you start needing it, and not at all when you really do.
The cooling part is a nice feature, but with a cage over my pool, it's never gotten above 90 in the summer... and water at 90 feels very cool when it's 100 out.
With regards to a variable speed pump - if a pool builder doesn't include one as standard equipment they are not worth hiring. This is basic 101 for a pool now a days. I can run my pump at 25% speed for the majority of the day - only ramping up when the heater needs to run (generally 1-1.5 hours/day).
If I run my pump for 10 hours/day, at 25% it costs me $1.91 for a month. At 100% it costs me $35.21. Quite a difference!
