<DIV><FONT size=2 face=Calibri>Comparing for example the Poly Kyocera and the
single crystal Solarworld and Suntech, there is less than 1/2 of 1% difference
in PTC derating. </FONT></DIV>

<DIV><FONT size=2 face=Calibri>Single crystal is often touted as being better
for low light conditions, and it is - but so what? On a heavy overcast
day insolation on the panel might be be down 95%. Single crystal is
typically about 3% better under low light, so instead of getting 5% of the
nameplate rating of the poly panel, you are getting 5.03% - or about the same
difference that a 1 degree panel temperature makes.</FONT></DIV>

<DIV><BR></DIV>No, IMHO.
<DIV>A polycrystalline module is never going to be "top shelf".<BR>
<DIV>
<DIV>First Quality would be Sunpower, Solarworld, Sanyo, ????</DIV>
<DIV>Check the new CEC module ratings. Apparently most modules were further
derated. A few stayed the same or went up slightly. </DIV>
