Solar Panel question

[RHRRC]

I am looking for information about small solar panels for a new
equipment design. The size will be sub 1W.
I keep googling for info but half of the internet seems to be taken up
with Solar Panel ads for large panels that, together with a suitable
12 1Ah battery and inverter, can be used to power most of southern
Europe through this coming winter.

Where can I find some useful information about the performance of
available small solar panels - or a suitable panel manufacturers
website.

I am quite conversant with insolation determination.

Thanks

try googling manufacturers:

BP Solar
Sharp Solar
Suntech Solar

Try the OEM modules from PowerUp.

Last we purchased, these ran about $20 US. (QTY-1, 1-watt panels).
Very nice construction!! I solidly recommend them.

Of course, after prototyping, we outsourced to China for about $8
delivered, 500-1K quantities.
Let me know if you need details...

You don't say for what voltage, or minimum current in ambient indoor
lighting. A fair number of small cheap ones are for calculators.


Farnell stock a few of the smaller ones and that will give you some
brand names to help find others. Same for RS

You could also try surplus stores for bankrupt stock ex solar fountains
and other failed gizmos that don't sell well.

There is a surplus house I have used in the US. They have a few listed. I
don't know if they ship to the UK

Is there a difference between a small Solar Panel, and an Encapsulated
Solar Cell...? I'm looking for 10 Watts (either 9 V, or 2 X 4.5V), and
have found both Panels and Excapsulated Cells, but I don't know the
difference between the two.

I want to fit it onto a surface that will be 6.5" square, so I'm sure that
is large enough, but don't know the difference(s) between the two solar
part types.

TIA for info!

When You find a panel that small that delivers that much energy, let me
know. I also would love to experiment with small area high output cells.

I currently have 4 RV panels that does an impressive job even with the
lack of light we have here compared to other locations.

I seriously doubt you will find a 10W panel to fit such a small
physical space.
The BP SX-10 model measures almost 11" x 16", for example.

I'm probably remembering something wrong, then...

But I'm still wondering what the difference is between a Solar Panel and an
encapsulated Solar Cell.

Just smaller panels in a frame set that electrically connection them
together with a protective package around them, transparent normally
with a single pair of wires for the DC output.

I know of some panels like that


http://www.spectrolab.com/prd/space/cell-main.asp


A panel that produces average efficiencies of 26.5%,

Ultra Triple Junction that produces efficiencies of 28.3%

AND - XJT produces 29.9% efficiency

I believe you would get close to 8W with the Ultra Triple Junction. And
yes you can purchase from them.

Designed for spacecraft. Have you any idea how much they cost ?

A simpler question might be simply "have you any idea ?".

How shove off out of a group that's for professional design engineers that
know what they're talking about and take your fantasy ideas to some obscure
alt. group. There's alt.savetheworld or something - should suit you nicely.

Yep, if you would have looked at the web page instead of just scanned it
over and make snap judgments like you do everything you would have
noticed.

Here in the FAQ



8. Q: For budgetary purposes, what is the price of the cells at large
volume?

A: Taking the CDO-100 cells as an example, at volumes of 10 MW per year,
we estimate the bare cells to be approximately $10 each and cells with
welded interconnects to be approximately $14 each. These prices will
continue to decrease with sales volume over the next few years.

A simpler question might be simply "have you any idea ?".

Simple answer "see above".

"How shove off out of a group" ? First of all, you need to learn how to
write.

And since this is for "professional design engineers" then this latest
technology knowledge should be something they should know about.

Let me guess, you got pissed when SMT came out.

Last time I checked, about $300M. But only if you want to send a
couple of robots to Mars. ;-)
