Most RE homes these days are 24 volt, and some are 48 volts. Smaller
homes and cabins can be 12 volts. Line losses are a real concern,
for sure. Wire sizing is important.
I'm guessing that your forklift voltages have more to do with the
_speed_ they want for the motors. Not much of a line loss issue
there. Large wires are required, but the distance is short.

In geo wells the object is not to heat the groundwater but rather produce a
constant temperature of the water flowing through a closed loop. The under
ground temp is always a constant 53-55 degrees. The old type system that you
may be describing is called a pump and dump, it requires a pump well that
draws water through your system and then returns the water to a dump well.
I personally am not to keen on that idea, since I belive it will eventully
raise the temp of the stream you are dumping into. The closed loop system
does not even require you to have any water in the well, rather just uses the
constant temp.

Yes, I've since been told by a friend that you can do this with back-to-back
FETS with very low loss indeed, but I don't know the control circuit details
to make a proper regulator with these (transistors and diodes I understand).
Go for it!  My friend also reminded me that the o/c voltage varies a lot with
cell temperature, so you may well find the FET idea worthwhile.  If I get any
further details, I may get around to posting back .. but don't hang out .. :)

assistant: o
Um, I'm not sure what sort of efficiency you're talking here, Alec, when the
very latest experimental solar cells are getting to around 25%, and
production ones are more like 15-20% tops?  Also, as I mentioned, 12V panels
that I've measured usually run about 18-22V open circuit?
Kali - you remember Kali? - says that on really hot days the o/c voltage can
drop to where a diode might start to be be a current limitation, but I've not
struck that much loss with heat myself, and most panels are designed with the
use of blocking diodes in mind anyway.
Still can't figure this, but knowing engineers, I'm sure there's some tricky
explanation :)  I mean I get needing headroom from o/c voltage for regulation
into say 13.8V float plus the 0.7V plus wire losses, but this 50% figure has
rather thrown me .. ?

Write your reply.

assistant: Alex,
The efficiency refered to in this case is NOT just the efficiency of the
engine at producing mechanical work, but rather the efficiency of the co-gen
SYSTEM at producing BOTH mechanical work PLUS recoverable heat.
In a diesel, about 1/3 of the heat value in the fuel gets converted to
mechanical energy (- giving the efficiency rating you are used to
seeing), 1/3 of the heat value is lost in heat to the cooling system,
and 1/3 of the heat normally goes out with the exhaust.
As a co-gen system, with the engine mounted in the space to be heated,
all the cooling system heat is recovered and a substantial portion of the
exhaust heat as well.  This gives efficiency as a co-gen system, as:
33% (mechanical energy) + 33% (heat recovered from engine cooling) +
say, a 78% recovery of the heat in the exhaust - .78(.33) or 26%.
SO.. as a co-gen efficiency is .33 +.33 +.26 = 93%.

That's at the top of the curve. Look at the whole curve and consider
what loads will generally be running before you assume that you will
actually get that kind of efficiency.
The advantages of a 24+ volt setup are for full-sized homes or
shops. Wire runs from arrays and wind machines are cheaper, and you
reduce multiple parallel strings of batteries.
For cabins and small houses, 12 volts makes some sense.
All AC makes the most sense in most new construction.
But 24 volt lighting and motors are easy enough to find.
