William, Thanks for posting a link to that story.
Here's more background on the tile roof integrated PV system recall and warranty fiasco: http://runonsun.com/~runons5/blogs/blog1.php/solworks/safety/suntech-recalls-solar-roofing-tiles http://runonsun.com/~runons5/blogs/blog1.php/ranting/centex-clouds-solar-tile-repairs http://runonsun.com/~runons5/blogs/blog1.php/solworks/safety/centex-suspends-solar-repairs http://runonsun.com/~runons5/blogs/blog1.php/solnews/centex-steps-up-will-replace It sounds like this could be a product design failure rather than a wire management issue. But wire management is certainly suspect until proven innocent. Regardless of the cause, since these are roof integrated systems, Centex basically needs to replace all of the TIPV systems with conventional rack-mounted PV systems—provided they can get the homeowners to sign the liability releases. Even though these are relatively unique installations, the general lessons would seem to apply broadly. Qualify your vendors carefully. Make sure your installers are properly trained. Put QC systems in place to catch problems. A small investment in quality wire management practices is cheap compared to the alternative.
