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,
Larry Crutcher

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?
