The only issue I take with your suggestion that these are Carrizo
modules is that as far as I know, all of the Carrizo modules (used
at the Carrisa Plains PV power plant near Paso Robles CA from
1984-1990) were made by Arco, not Solarex.<br>
<br>
Also, the Carrizo Quad-Lams required four in series, not three. A
few of the better modules could reach 16V in hot weather in sets of
three, but the vast majority couldn't, especially after premature
degradation caused by the use of reflectors on most of the tracked
arrays. They were called Quad-Lams by Carrizo Solar (who bought the
plant and cut them up for resale) for this reason. Photocomm sold
some as sets of three (and called them Tri-Lams) in the early 90s,
but after haranguing by Richard Perez of Home Power and others,
supplied a fourth module to purchasers, as sets of three had
insufficient MPP voltage to EQ a 12V battery during summer heat.<br>

I had modules like those back in the early 1990s, when I first
went off grid. They are designed to be wired in sets of three for
12V nominal, 18Voc. If the EVA encapsulant is a bit browned it is
probably leftover from the Carrizo project, the largest of its
time. The Carrizo project had reflectors to increase output but
they cooked the adhesive. The owners eventually lost their
beneficial rate and realized they would make more money selling
off the modules than selling the electricity. Many homesteaders
benefited.

The label looks like a shiny piece of foil, but with light angled
on it
<br>
just right way the name Solarex is visible as are many words on
the
<br>
label template. None of the values are legible. It is a little
smaller
<br>
than a MSX-60. It has 40 cells that are wired in four parallel
strings
<br>
of ten. Open circuit voltage is about 6 volts. Shorted it put out
4 amps
<br>
in bright but very overcast conditions. I suspect that it would
put out
<br>
8 to 10 amps at STC. There are two j-boxes, one on each end, with
very
<br>
substantial terminals. It still operates, but obviously it isn't
much
<br>
use for charging a battery, even a six volt one. Anyone familiar
with a
<br>
low-voltage high-current Solarex module.
