I've done this. Hopefully, it will be useful later. Right now, it doesn't help me enough - without putting something into practice.
Holy snikies! That one is going to have to wait until another day. I will need some time to take all of that in. Looks like some very intriguing stuff though.
Thanks much,
Take care,

A scientific approach to this would be to eliminate the variables that
can be eliminated, and keep records of those that can't be eliminated.
For example, measuring ambient temperatures and comparing those to the
temperatures in the collector will let you know to some degree what your
insulation is doing for you. Taking internal temperatures without
removing the heat, (not pumping water through your tubes) will let you
know what max temp you might expect, all else being equal. (Length of
time the sun is insoling at a beneficial angle, ambient temp, insulation
value...) Some numbers in the basic setup will then indicate how
quickly you might want or need to pump your coolant through the tubes to
draw the heat from your collector.
Then you might adjust your input for those low angle incident rays by
mounting a reflector that will redirect reflected rays back into your
collector.
These all sound like good recommendations.
The area of your collection surface will determine the maximum kWh
capacity of your panel. A search using your location and the term
"insolation" will likely return you some very useful data.

Duane Johnson has a huge website dealing with, among other things, solar
energy. Great numbers of links will guide you through any aspect of
your endeavors. His site is at http://www.redrok.com/main.htm
