Long Beach Solar Convention[RE-wrenches]

[August Goers]

I was also down at the convention and expo and noticed the plethora of
Chinese manufacturers.

Since we carry a 10 year warranty on all parts of the system I am certainly
not willing to select no-name Chinese made products for our jobs. We can't
afford to take panels off the roof. My experience with smaller Chinese
manufactures from my work in the automotive field is that their quality
control can vary from shipment to shipment. Big companies like Sun Tech
probably have their QC down and I have to admit that their PV modules look
good. 

All that said, some of the best and most reliable products can be
manufactured in China. My laptop, an IBM, was made in China and it has been
great.

I think companies need to be selected on a case by case basis and not so
much on where they are from.

I am sure many on this list was at the show, but I did not see any of you
most likely because this was the most crowded business to business solar
convention I have ever attended. It looks like solar has really come into
the mainstream!

On several past posts I have mentioned my concern for products made in China
and the problems we have had with many of these. To really drive this
concern home, I have never seen so many new solar modules and inverters made
in China, and I must admit they look good. However, my experience and
concern is that many of these great looking products will have all kinds of
problems that will not show up until after installation, and I would hate to
try to work out a warranty repair while talking with somebody at a service
desk in China with who knows what kind of time difference.

While checking out the booths I know I picked up at least 30 to 40 different
module specification sheets and all were modules made in China. Yes, they
really do look just like quality Made in USA modules, but then, so does
their compact fluorescent light bulbs! Anybody else see this storm on the
horizon?
