Evergreen Blemished Modules

Does anyone have any pictures of these modules showing the blemishes?

I have a client who is interested, but wants to see a picture.

    Yikes - that doesn't look like a "blemish". It looks like one entire cell is missing, not a color variation. Maybe other cells from a 220w panel are high enough that it puts out 200W.

    Mike,

    The cell is there, its just off color ... the ones I have has some waveyness in a couple of the cells screen printed pickup traces.

    Evergreen are just about the best panels now on the planet, maybe the "B" and Sun versions wouldn'y cut it for framed artwork, but for power production there is no better bang for the buck

    Solar Guppy - did you mention at one time, or do you know, of PV panels that have a better "off-angle" output ? When bolted to a roof, they can only be aligned for 15 min or so, and the rest of the day, they are "mis-aligned" I figure, what I loose at peak, would be made up in gains the rest of the day.

    Mike,

    Mono's are slightly better ... but IMHO nothing beats the Suns or "B" grade Evergreens. Whatever some fancy Sanyo HIT Bi or SunPower Black or Solar World or BP mono have in same efficiency can't match the 50% better price per watt these Evergreens have

    They have 205 Watts for 2.50 watt ... do the math and you will have your answer

    oops, looks like an Evergreen cell, I should have looked more closely, however, it looks like a module made with reject Evergreen cells, I believe. That means it was not an Evergreen B (blemished) Module, I think.

    Solar World are about the same price as Kyocera and Evergreens.
