Hiya Jeff, You are correct that the sunpower modules are positively grounded. You are also correct that sunpower only deals with dedicated "dealers". That means that if you are not one of their dealers you cannot get their panels. It is my understanding that sunpower is always looking for new dealers, so you may want to check in with them. As far as architectural review committees and such, we have never had a problem using SPR modules in the areas where review is an issue. The positive ground really does not affect aanything. Instead of your negative wire being the grounded (white) conductor it is your positive conductor that is grounded. This means you are switching the negative instead of the positive in the DC disco. Sunpower sells packaged systems, so they provide positive ground inverters from different manufacturers.
Evergreen now has a black framed module, and I believe Sharp does too. I hope this helps, any other questions feel free to contact me.

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.
