[RE-wrenches] Bosch/aleo PV module warranty excuse for a hotspot

[August Goers]

Hi Pekka,



Oh boy, this sounds bad. I know that early modules < year 2000 had a lot of
hot spot related issues, but I haven’t personally had any in the recent
past. This sounds like a total excuse. All modules may get dirty. The last
time we had a module producing low energy, the module manufacturer (Suniva)
gladly replaced the module after we sent them voltage and current readings.



Out of curiosity, what kind of glass soiling did you have? What are the
symptoms (low production, discolored cells, burned traces)? We’ve installed
some Aleo systems and I’ve attached the warranty info that I had on file in
case it helps.



Best,



August

Hello wrenches,



Has anyone ever gotten a similar response from Bosch/aleo for a warranty
claim on a "hotspot."



"

Sorry, this is the result. Soiled module glass is the cause, this resulted
in current surges and HotSpot on the cell. External influences (shading) is
not a part of the aleo product and performance guarantee.

We apologize for any inconvenience this may cause to you.



Mit freundlichen Grüßen / Best regards

So they are saying the dirt on the glass caused the problem.  How
convenient....that response can be used to derail every claim. These panels
should be designed for ourdoor use. Th <http://use.th/>at is total bs. So
does their product lliterature state dirt is a problem and indicate how
often they should be cleaned.

Should we as installers accept this?
