<DIV><SPAN class=390375106-15122008>Something in your description doesn't jive,
Bob...53W panels are most likely 12V nominal, such as Solarex VLX53; typical
poly 12V, so 17 VMP - a string of 8 would be 136V; why are you claiming 53V? Is
it 4 strings of 4 modules each? </SPAN></DIV>

question<BR><BR></FONT></DIV>

<DIV> </DIV>
<DIV>I am doing an upgrade at a site with 16, 53 watt panels wired
into 2 strings of 8 panels each coming into the controller at around 53 or
so volts. The upgrade is 8, 175 watt Solar Worlds at around 70
volts. </DIV>
<DIV>Here is the question the customer is telling me that he has seen the old
rack putting out more power than the new rack that is almost 2 X the size.
</DIV>
<DIV>Both are side by side and nearly the same tilt, shading is not a problem
and the 60's were bought at the same time.</DIV>
<DIV>I have never seen this happen at the times I am on the site.</DIV>
<DIV> </DIV>
<DIV>Has anyone else seen any weird problems like this? I have other sites with
2 or 3 flexmax 60's and this has never been noticed before at those
sites. </DIV>
<DIV>I don't have any confirmation of this and have not called Outback about
it.</DIV>
<DIV>Just picking the collective brains so to speak......</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
