No kidding, the amount of solar heat can be really appreciable. The
figure for insolation being around 1200 to 1400 watts per square meter,
it is easy to see how your wreath would toast nicely between 2 doors.
Imagine a wall solar collector of about 8 x 3 meters, that would mean
30,000 watts of heat!!! Even on a 50% overcast day that would be still
be 15,000 watts.
The figures are extremely attractive without doubt. The big problem of
course is one can't expect to have the ideal conditions every day and
then of course there is the night. Also sometimes the sun doesn't show
itself for a couple of weeks in fact.
What I had in mind was to put the heat energy to use in the summer to
power some kind of heat pump engine that would run an air conditioning
unit. So that the sunnier it gets the better the air conditioning works.
