Wrenches,
A customer dropped off an unusual PV module a couple days ago. It's not
a design that I'm familiar with. I'm hoping that the vast wealth of
distributed knowledge contained in the RE-Wrenches may recognize it and
explain its purpose.
The label looks like a shiny piece of foil, but w
Kent,
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

Does it have jumpers that would lower the current and double the voltage?Maybe
unbridged and still attached? I have a dozen Solec modules that were either 12
or 24 volt nominal output.It has been a long time since I was in the J boxes
but it seems like they may have looked as you are des
Nathan,
There are no jumpers, each j-box has a single terminal. It has 4" square
multi-crystalline cells, a 2" bronze colored frame, and measures 17.5" x
42"; just a little smaller than a MSX-60.

Hilton,
That description sounds like some old modules I used to have. I thought they
were from the ARCO project. Same circumstances I think. As I recall the modules
were Tri Lams (not sure on the proper name for them) but they were also 3 in
series for 12 volt nominal. At least the ones I had
Hilton,
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.
Also, the Carriz
Allan,
Your right about the modules from Carrizo being made by Arco. And
weren't they mono-crystalline? Three of these modules in series would be
30 cells and not enough voltage for charging a 12-volt battery. But I
think that's the biggest similarity to a Quad-Lam.

ord. These are beginning to have interconnect failures which I am able to repair. Luckily my clients aren't too demanding.Just a bit of history/reminiscing - the "unusual module" is clearly not one of these.
