Put the panels in parallel.


Regulated by temperature.


I'm thinking to use a plastic cubitainer or a wooden construction with
plastiek bag in it (swiming pool) and put in heat en take out heate with a
heat exchanger (copper tubes in the reservoir)..


I think this is not so easy with a big panel. But if you can do it its very
good.

 Hey Guys:

Thanks for the replys.

1) & 2)  OK, parallel it is.   My initial thought with the
"series-parallel" arrangement was to meter the flow rate based on
discharge temperature.  I can see where the parallel arrangement would
be much simpler to operate.

3)  This seemed so clear when I wrote it, now I'm not sure exactly what
I was asking... I was wondering what y'all have been using to store the
hot water in.  I haven't quite figured out yet how much storage I will
need based on the collectors, but I am thinking that if I get too large
of a container my water will not get as hot since I am recirculating the
same water most of the time.  Seeing how others have done their's I am
thinking either a domestic water heater tank (or two) or a small
ag/industrial storage tank - whichever one is least expensive.

4)  OK, tracking the sun is out, at least for now.  Seemed like a good
idea at the time.

Thanks
John

As storage:
20 years ago I took 2 metal reservoirs of 1000l. These were old expantion
reservoirs from the centrale heating of a school, I could bouth this very
sheap. This two reservoirs were in line and filled with water of the
centrale heating system so pressure was about 1 Bar. I can tell you, for 25
m2 panels in summer 2000l water gives you 60 a 80C and in winter, we cut
one reservoir, 1000l gives you 35 a 40 C. Don't forget the 200 liters
sanitair reservoir always will warmed up primair at 45C.
Now I'm looking again for 2 reservoirs but can't find it anymore second
hands. The new price is about 600 a 800 dollar, to expensive I find. I'm
thinking of using a plastiek cubitainer of 1000 l (second hand 50 a 100$) or
a 1000l plastiek reservoir for heaing oil (new price 150 a 200 $) or even
making it in wood and put a plastiek bag in it, price? ....   Wen you work
with plastiek reservoirs the pressure on it must be 0 bar, open to
atmosfeer! So the centrale heating system must be separeted from the
reservoirs, you must transfer your heat with a heat exchanger. Problems for
the first two idees is, how to put in the heating exchangers (copper tube
spirals), I have to make holes in the reservoirs ... so I'm thinking on that
....
All this of  20 years ago is on our homepage with pictures, try looking also
the dutch page for my new project zonneverwarming, I'm working on it now.
If sombody has better idees for a reservoir .....
