<p class=MsoNormal>Hi Wrenches.<o:p></o:p></p>

<div>
<p class=MsoNormal><span class=apple-tab-span> </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 class=apple-tab-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 website?<o:p></o:p></p>
