<div>Hi Wayne,<br /><br /></div>
Several years back I had all sixteen SolarWorld modules on a tracker get zapped. The two other trackers adjacent to this one had no damaged modules. The same strike blew out the phone box at the end of the road (some distance away). <br /><br />The SolarWorld jboxes were all sealed with no way to get to the diodes. The homeowners insurance covered the loss and I replaced the modules with something similar (SW had since stopped manufacturing 175s). It would have been nice to have had access to the diodes.<br /><br /><br />-- <br />

<div dir="ltr"><span style="font-size: medium; color: #000000;">Hello Wrenches,<br /><br />Today we visited a 10KW residential ground mounted system where there was a recent lightning strike that fried phones, irrigation system, cable and apparently the array.<br /><br />There was no external visible damage but also no voltage at the combiner. We pulled 10-15 module junction box covers off and only saw clear evidence of damage to one diode. There was no Voc on any of the modules.<br />While I recognize that Florida is arguably the lightning capital of N America, I have never seen an entire array fried.<br /><br />Has anyone on the list ever seen an entire array fried?<br /><br />The modules are Schuco 230's. </span><br /><span style="font-size: medium; color: #000000;"><span style="font-size: medium; color: #000000;">Obviously not covered by warranty and Schuco has pretty much bailed out of the US market.<br /><br /></span>Does anyone have experience repairing these modules?<br /><br />Any similar experience and/or advice would be appreciated.<br /></span><br /><br /><span style="font-size: medium; color: #008a17;">Wayne Irwin</span><span style="font-size: medium; color: #008a17;">,</span><span style="font-size: medium; color: #008a17;"><br /></span><span style="font-size: medium; color: #008a17;">President</span><span style="font-size: medium; color: #008a17;"><br /></span><span style="font-size: medium; color: #008a17;">License #CVC56695 </span><span style="font-size: medium; color: #008a17;"><br /></span><span style="font-size: medium; color: #008a17;">State Licensed Solar Contractor</span><span style="font-size: medium; color: #008a17;"><br /></span><span style="font-size: medium; color: #008a17;">Pure Energy Solar International Inc. </span><span style="font-size: medium; color: #008a17;"><br /></span> <span style="font-size: medium; color: #008a17;"><a href="mailto:PureEnergySolar@hotmail.com" target="_blank">Wayne@PureEnergySolar.com</a></span> <span style="font-size: medium; color: #008a17;"><br /></span> <span style="font-size: medium; color: #008a17;"><a href="http://pureenergysolar.net/" target="_blank"></a><a href="http://PureEnergySolar.com" target="_blank">http://PureEnergySolar.com</a><br /><a href="https://solarchargingstation.net" target="_blank">http://SolarChargingStation.net</a><br /></span><span style="font-size: medium; color: #008a17;"><a href="tel:352%20377-6527" target="_blank">352 377-6527</a> Office</span><span style="font-size: medium; color: #008a17;"><br /></span><span style="font-size: medium; color: #008a17;"><a href="tel:352%20336-3299" target="_blank">352 336-3299</a> Fax</span><span style="font-size: medium; color: #008a17;"><br /></span><span style="font-size: medium; color: #008a17;"><a href="tel:352%20316-1637" target="_blank">352 316-1637</a> Cell</span><span style="font-size: small; color: #008a17;"><br /></span><span style="font-size: small; color: #008a17;"><br /><span style="font-size: 12pt; font-family: 'Comic Sans MS';">The Sun Is Always Shining!</span><span style="font-family: Arial;"><br /><br /></span></span>
