Hi Jeff,
We have sold the quite a few Sunpower 90's. After they became
unavailable, we started purchasing CTI 90's (Carmanah Tech.) made with
the Sunpower cells. Both modules have exceptional performance in high
heat. The efficiency and temperature coefficient is second only to
Sanyo. The CTI's are not positive ground. No failures, highly
recommended.
Kindest Regards,
Larry Crutcher

We have installed systems using many different module brands and
sizes, but so far we have not installed Sunpower modules.
When we checked their web site it appears they only deal with their
own "dealers". Since we buy hardware from many different national
distributors, are these available without being a "dealer"? It
seems like everyone wants you be be their "dealer" before they will
provide any information on their products.
I also thought their modules are "positive" ground to achieve a
higher efficency which can alter the grounding wiring design and
type of inverter selected. Is my memory failing or perhaps thinking
of a different product.
For those that have used this module, what has been your
experience. Where are these manufactured?
The only reason I am considering thie module is one of our client's
needs a totally black module in the 200 watt range and none of our
other suppliers offer this at this time.
Thanks,
Jeff Yago
