Uni-Solar put out a low-performing (some might call them defective?) batch of US-64’s back around 2004 I believe. As an employee of Uni-Solar’s primary North American distributor I’ve seen a couple of these cases crop up. Jay, if this system was installed in the 2003-2005 time frame, and the cells have the slightly reddish outer edges, then they’re suspicious.
