Does anyone have experiences with UNi-solar panels

I have a 34 W peak foldable Uni-solar
2 kg and small enough for every backpack

Given their exceedingly high $/watt, (.vs. claims that they would be
cheap due to the manufacturing method), no. You need to have too much
money, or a desperate need for flexible panels for those to be a
non-insane option...
s said:A 64w unisolar panel will perfrom at the samelevel as an 80w crystaline panel.
DOnt just look at the price when looking for panels look at how they
perform at real operating temps. If you look around you can buy
these panels at good prices check out. www.unisun.com.au

Links please to your "research" and if your into research, look into the

Solar Guppy said:Well for starters, Unisolar claim for more "energy" delivered is a single
test done in 1998, from there own marketing bla-bla-bla called solfest shoot
out. There is no reference to the monitoring methods, such as pyrometers and
such, so the actual data is suspect.
They used 4 uni-sloar modules that were only 133 days old and compared them
to some astro power panels, which are hardly the best of either ploy or mono
crystal technology. Its takes anywhere from 6-12 months for A-si to do its
"stabilization period" during which its common to have a 20-25% drop from
the initial out of the box performance
Many manufactures have abandoned the technology, most recent was BP after
investing 10's of millions, I personally know of arrays that are 15+ years
old that are under 50% of there name plate rating. Asi does respond
differently to cloudy conditions due to the ban-gap differences, and under
these conditions is will out-perform Si panels, but 20% difference when the
total output is only 10-15% of 1000 watt/meter/sq is a pretty pointless, put
it this way, your talking about a 2 watt difference in the overcast
condition for a 64 watt panel.

described what ALL of there marketing is based on
I know there was a huge test going on in Europe, doing long term testing on
all major manufactures, all the thin film were doing very poorly in years 2
3 and 4. Some further tests showed that re-baking the modules brought back
some of the performance, but by this time every one except unisolar had
abandon the technology. I looked for the link and it didn't come up on
Google ...
this research does not state what the brands are so therefor it cant really
be used as true comparison
A-si and various other thin film technology is not dead. I am not
talking about the cheap units you can purchase at auto shops.
please dont knock technology you dont fully understand.
I just noticed that ICP makes aSi panels.s said:sorry typo

It is quite obvious from all your comments that you know little or nothing
about the business or the technology. Panel deformation???
I suggest you stop posting and start reading.
It is no wonder people here get pissed off when
somebody lays a joke or sarcasm on them. Most of the
are so out of reality here from pissing into the wind
and staring at the sun too long...LOL
wakey...wakey yahoo boy

products!
Perhaps he means "defamation", or defaming their
products.
If someone placed an order and it was not filled and
to a date in the future, is not defamation, it is
fact.
What people chose to think about it is their
love to know about your open deformation of their products!
Solar Guppy said:More Asi data, here is a report by Fsec on the degradation issues
specifically, there is also long term leakage issues with this particular
brand (no longer produced as Arco/Siemens exited Asi production)

Again. yet another document shows what others have shown, to quote the PDF ,
the panels are running at 55% of name plate rating
