<div id="signature">Bill, I remember the warranty was not great and the ones I had experience were not top Tier. I am thinking dumb looks are still free and a Seventeen year old installation is going to be more free time for you. I hope I am wrong, good luck!<br />

<p>I went back to this array, removed all J-box covers and tested for Voc. The majority of the PVs were ~ 9.5Voc, about 5 were ~19 Voc, 3 were 0 (that's zero) Voc . The diodes are in an encapsulant. The label says Voc = 22V. Another array of Mitsubishi panels takes a dive.</p>
<p> Anybody have contact info for them or recent experience with their warranty?</p>
<p>Thanks,</p>

Basic stats: 23, Mitsubishi <br />PVMF120EC3, label says V mpp= 17.6V and Voc = 22 V; top-of-pole; SMA <br />SB3800U. Its one string of 23 PVs. Full sun, 75 degrees ambient during <br />testing. When I checked DC voltage at the inverter landings I got ~23-29 <br />volts (fluctuating) same at the input side of the DC switch. These <br />panels have the old gasketted 4-screw covered J-boxes and screw <br />terminals inside, I removed the covers from three panels and got 9.5 <br />volts at the each of the panels' screw terminals, all the wiring <br />outside the boxes checks out.<br /><br /> The system had been functioning normally 3 weeks prior. I <br />could check voltage at more panels I guess. Ideas?<br /><br />Bill<br /><br />Feather River Solar Electric<br />Bill Battagin, Owner<br />4291 Nelson St.(shipping)<br />5575 Genesee Rd.
