Anyone know of a supplier in the states with some in stock?

Larry, 

 

Thanks for this update, no evidence of degradation after 10 years is
encouraging.

 

I am well aware of the performance edge they have, having cross brand tested
them myself some years back.

 

There are still a few US64's for sale here, but soon to run dry I expect.

 

Pity the Canon Corporation who pioneered the technology pulled the plug on
the 5 junction panel development due to an economic recession.

 

Cheers, 

 

Carl E

Hi Carl, 

 

I have installed hundreds of US-64's and ES62's, on grid and off. I don't
have any documented data but I see the performance as the very best,
especially in hot climates and low light conditions. Where I am located we
have above average irradiance, 1050~1100 w/m2 and very high UV radiation. I
have tested several panels that are 8~10 years old and all still output more
than their rated power by 3% to 10% (Isc adjusted for irradiance and temp.).
I have only experienced on module failure ever. 

 

NREL has studied Uni-Solar modules and found that they produce 20% more
power annually than crystalline modules (eg. Santa Cruz test site). In
Australia, a very hot test site produced 30% more power than Solarex
modules. Want more? In Hopland Ca. in June 1998, Real Goods did a "shoot
out" comparison with SP75's and AstroPower AP7105's. Result was the
Uni-Solar performed up to 32.2% better!

 

I really like promoting high performance products for my customers but
Uni-Solar has stopped making framed panels (and yes, I am sad) to devote the
production to the laminate market. Are you still able to get any framed
panels in NZ?

 

Kindest Regards,

Hi there,

 

Anyone got some real world performance data that shows how well the Unisolar
US64 panels are holding up after several years in service?
