Subject: What heats water faster ? hotter/slower flow ? or faster/colder flow ?

I have a good question on heating pool water, by adding BTUs to it using a
solar heater.

My question is this:

Is it more effecient to heat a large pool (18 foot above ground, 52" high )
with a slower rate of water at a higher temperature of water
coming from the solar panels....

or, is it better to have the solar panel output much faster which makes the
output MUCH lower in temperature ..... ?

If I slow the output from my solar panels, I can really get very hot water
coming out of my solar panels, but this means a slower output,
but if I run my output very fast, I get very good output, but the temp
coming from the solars is only about 5 degrees higher than the pool temp.

If you can forward this to anyone that would know how I could find out more
info about this, it would be much appreciated.

Thank you in advance,
