[RE-wrenches] Sanyo problems

Sun Apr 3 09:01:38 PDT 2011

The current HIP-195DA3 datasheet is here:

http://us.sanyo.com/dynamic/product/Downloads/HIT%20Double%20195-1483134
.pdf

So it appears that the DA designation means bifacial module... You are
correct that not all HIP modules are bifacial. For example, the current
model numbers HIP-195BA20 and -195BA19 (aka HIT Power 195) are not
bifacial, but do have the "rear-side electrode" below the thin silicon
layer. This is what makes it a bit confusing if not familiar with the
modules.

The marketing name of HIT bifacials are "HIT Double." All bifacial part
numbers start with HIP, but all HIP part numbers are not bifacial
modules. Sanyo is not doing itself any favors by making the model number
designations so confusing.

Bottom line: I need to figure out if the HIT Doubles (bifacials) are
affected by these alleged problems. I would assume problems that affect
any HIT module would also affect the bifacials, so I may have partially
answered my own question.

I don't know my HIPs from my HITs either, but I don't think you're
correct, Jason. I checked a bunch of pdfs of spec sheets for various
Sanyo modules, and it just left me more confused.

The Sanyo HIP-190BA3/195BA3/200BA3 is a single-face module from around
2006. On the spec sheet is written: "SANYO HIT1 solar cells are hybrids,
made of thin mono crystal
silicon surrounded by ultra-thin amorphous silicon layers....SANYO HIT
solar panels have a black anodized aluminum frame, come pre-equipped
with lead wires and plug-n-play connectors.

The HIT Power 200 from 2008 has on its spec sheet "HIT Power 200 or
HIP-200BA19"; also single-face.

The HIT Power 215N is listed on the spec sheet as "HIT Power 215N or
HIP-215NKHA5". 

The HIT Power 200A is only an HIT; the specs list it as "HIT Power 220A
or HIT-N220A01", and there's no mention of HIP on the sheet.

Enough already! Marco, can you send out the Photon article after all? I
don't think you were mistaken. Maybe we have a real concern here after
all.

I believe the HIP denotes bifacial HIT modules. These are exactly what
is being proposed on the project I am working on. Might need an
alternative!

I don't know my HIPs from my HITs...wait that didn't sound right...but
you see my problem. "Heterojunction with Intrinsic Thin Layer" = HIT.
What = HIP?

Thanks for taking a moment to address this question. Marco & others: if
anyone can find a Sanyo Tech Person who would join the Wrench List, it
would help us all and probably also help Sanyo.

Esteemed colleagues,

Regarding the Sanyo problems, I was mistaken.

They're having problems with their HIP models.

I'm seeking clarification from the author of the article who I know to
see whether there have been any HIT problems as well.

My apologies.
