Two of our projects this summer had panels that were putting out half of their rated voltage. At first it seemed like it was a defect from the factory, and it was caught upon commissioning the system, but I'm now seeing that another panel has gone bad about two months after install. I've spoken with a few distributors and they said they haven't heard anything about this being a pattern. I'm in the RMA process with QCell, and don't feel like I'm getting complete transparency from them. So far we have 8 defective panels out of 300. It was in two different projects that were months apart. I'm not sure if they were from the same shipment or not. All of them were<font style="background-color:rgb(255,255,255)" class=""> Q.PEAK DUO 400 watt panels. Interested to know if anyone else is having similar experiences?
