We used a few a while back on some Grundfos SQF pumps, but quit when we
figured out that the extra shipping and mount costs made them about the same
price per watt as a standard UPS shippable panel. Note that the 60 watt
Kaneka are NOT UPS shippable, while the Kyocera 130's and similar sized
panels ARE. The Voc is also around 80 volts, so you need an MPPT controller
for battery systems.

In Photon's side-by-side module test a few years ago, I remember that one
of the worst-performing modules (in kWh/kW) had marketing materials that
targeted the off-grid market. The author suggested that by targeting
off-grid, they were able to obscure their low production- perhaps another
reason why this email is targeting that market.
That being said, those 98c/W Kanekas look interesting...

That 98c/w is for those Kaneka high voltage thin film panels. Not a bad
price per watt, but they are pretty inneficient - around 7% - so they
take up twice as much space for the same watts.
The blems that I saw were also more than just "spotting".

Hi all,
The message below was received by a friend of mine who has done all his
own installation work, including being an early adopter of the FIT
program
while living in Germany many years ago. He is wondering if this is a
good
deal for his off-grid system.
What thoughts are there about the points made in this pitch? This is the
type of marketing that more and more of my clients are seeing.
Has anyone had any traffic with Sun Electronics that they care to relate?
And, I thought at least the Evergreen blemishes were about minorly
misaligned cells, not spots.
Thanks,
Howie
