Re: [RE-wrenches] panel failure

Great thanks for the reply Jay, at least I know someone else has seen the same thing. Odd that it would just happen on 4 panels unexplainably. Maybe a transient from a lightning strike or something. Ron > On Sep 16, 2015, at 7:37 AM, jay wrote: > > HI Ron, > > I have

Re: [RE-wrenches] panel failure

Thanks Allan, I was wondering about the lack of response as this group is always very helpful. One begins to suspect the phantom cause, i.e. the rest of the story that wasn’t told to us by the customer. It happens from time to time ;-) Ron > On Sep 15, 2015, at 9:07 PM, Allan Sindelar

[RE-wrenches] panel failure

HI Ron, I have seen this a few times. And just a month or so ago. You can measure VOC and its right. You can measure ISC and its right, but no power. As someone said, there is a weak/bad connection. Usually its on a main ribbon. Its just barely making connection. Enough you can get VOC.

Re: [RE-wrenches] panel failure

Ron, The lack of response may indeed be your answer. I didn't reply because it hasn't happened on my watch and I have no idea what would cause what you describe. Allan > On Sep 15, 2015, at 8:30 PM, RM You wrote: > > Just wondering if any esteemed wrenches have an

Re: [RE-wrenches] panel failure

Just wondering if any esteemed wrenches have an idea what could cause this problem? Customer says nothing unusual happened that he is aware of and the panels had been working fine for many years but now 4 of 6 panels just quit. Doesn’t appear to be a diode failure. Ron > On Sep 11, 2015, at

[RE-wrenches] panel failure

I have a customer who has 6 siemens 48w panels that are 20 years old (hooked in parallel to a 12v battery). He says that 4 of them have failed in that there is no output unless he bypasses the diodes. However he pulled the diodes and checked them on a diode check and separately on a battery

Re: [RE-wrenches] panel failure

Although i cant vouch for 20 year old siemens, my siemens modules (14 yr old sp-150s) had an intermittent connection develop between the stainless ribbon that exits the back sheet and the terminal where the blocking diodes connect (3 diodes). There used a spot welder to join the materials. This
