Does anyone have any experience with evergreen blemished "B" panels? I found them at www.sunelec.com for $.40/watt less than the normal evergreen models. I was told they are cosmetic blemishes only, and don't affect the output at all. However this was from a salesmen, so not sure if that is true. Has anyone actually tested or used these panels? Would love to save the money if the performance is the same, but couldn't find too much outside information on these panels. Thanks guys.
