[GBlist] Solar Panel (was Units of Measure)

[Sacie H Lambertson <dlambert@grasshoppernet.com>]

Am afraid your responses to my query about how one figures out the #s of
solar panels has gone off in an unintended direction.  Don't mean for there
to be anything in the original that suggested these panels are PV.  
	What I am about to place on a roof are passive panels for heating water;
they'll have glycol running through them, a heat exchanger, a pump etc.  I
have to figure out an appropriate # of panels (4'x8' one or two), the
optimum size DHW heater for this application and whether it is worth buying
an electric DHW heater since those are the least expensive for the size and
the most efficient to operate.  
	Given the fact that Kansas has super sunshine, I expect not to pay a
utility company to heat my water.   I am heating water for two
economy-minded users and a radiant heated floor.  I would prefer not to
have to guess about sizing the various parts of the system.
	One of our listers (from whom I bought the panel(s)) suggested I take a
large electric line up to the roof as a conduit for DC current from a
future PV panel.  Excellent idea that I will use.
	Bottom line, I would appreciate some guidelines for the # of panels
question and for the size of the water heater as storage tank (and no
arrows about the electric please).
	I appreciate the education I am receiving through the answers to the other
questions, the PV one.  I'll store these for future use.
