We have many installations in Southern Texas and many customers there have given us excellent feedback on their pool temperatures. We've found a pretty good correlation between what the computer simulations tell us and what happens in real life. The curves above represent a full sized solar heater.
We've plotted the daily maximum pool temperatures. Note that a cover doesn't help all that much in this area. We size systems higher if you won't use a cover but notice that 12 collectors and no cover (100% of pool area) equals the performance of 8 collectors (75% of pool area) and a cover.
Also notice that it looks pretty much impossible to heat this pool December and January. The typical meteorological year weather data is taken from Brownsville so if it as few degrees warmer where you are you can scale those temperatures up accordingly. We included daily peak air temperatures on the plots so you could make that comparison more readily.
Given regional climate fluctuation and the fact ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
