Re: PSPICE Modeling of Solar Panel and Battery

One other thing... that Wikipedia entry is for a *single cell*, which will get
you about 0.6v -- for a standard 12V panel, you end up with a bunch of single
cells in series. In practice you usually use 24 to get an open-circuit
voltage of around 14.4V -- some partially shaded cells, loading, etc., drops
this; the idea is that you still have a useful 12V output.

There's lot of good info on PV out there -- the University of New South Wales
(UNSW) in Australia used to have an on-line course about them, which was
surprisingly good.
