<P class=MsoNormal><SPAN style="COLOR: #993366">Note also that the MSX series
was known to have some defective modules. They showed correct Voc and Isc but
essentially a flat I/V curve slope, meaning very weak output; that was a real
headscratcher for installers. I had a set of 12 from around 1994 with this
behavior. Solarex never recalled this bad series, but I heard about it from
another old-timer. Solarex replaced all of mine under warranty, but warranties
back then were 10 or 12 years, so by now expired. Of course, back then there was
a Solarex… But they knew which serial numbers were prone to be
defective.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN style="COLOR: #993366">I would encourage you to test
array output before putting any effort into making it a GT system. If these are
low output, push hard on BP(?) to cover them as known to be defective.

</SPAN>I have a customer with 32 of the Solarex MSX-64 solar panels an a
battery-based system. He wants to go batteryless inverter. So I am
looking at 2 strings of 16 in series. But the solar panel
spec sheet doesn't say anything about <SPAN
class=apple-style-span><U>system</U></SPAN> voltage rating. Can I do
this?<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><SPAN
class=apple-tab-span>
</SPAN> If one solar panel in the string is shaded, does it see the
full string voltage of around 280 volts? Is there something in the way new
panels are made that makes them more able to handle this voltage, or is it just
that they are now tested for it?<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><SPAN

</SPAN>My guess is this request may be happenning a fair amount. Is there
a reason these panels are not listed on the California GoSolr
