I put out another FB shout got one chap who was interested until I mentioned lichen and said he couldn’t do it and I would need a specialist company.

They obviously have no knowledge of what they're doing then as lichen isn't a problem. 

 
heres a pic of the panels. apart from the lichen whats causing the milky grey patch in the lower right corner of each panel?

How old are those panels??? I could be wrong but it looks like water has got between the glass and the actual inner workings of the panel , we have cleaned tens of thousands of panels over the years and I have never seen anything like that before

The white haze is moisture ingress through delamination, I've seen this on a much smaller scale with utility street furniture enclosures used within traffic signalling where they use A4 size polycrystalline panels to power a backup charge circuit within a switching system.

Be interesting to see what the comparison in performance between that array and another that's not showing the same signs of wear and tear

Yes that’s what I thought it was but never seen it like that before and we have cleaned a lot of panels ????

 
the array is about 7 years old. these are Solarworld panels that were made in Germany and supposed to be the muts nuts.

ive emailed the company who installed them and said its thought this is water ingress. the problem is the company Solarworld Germany have gone bust. but i would assume the warranty should be covered by a third party incase of them going bust?

Not sure what the warranty period is but if it’s 7 years old would have thought it’s probably expired . Let us know what the outcome is .

So are you a window cleaner or home owner? 7 years I'd say they are expired and need replacing

 
im a homeowner and had the system put in in 2014. they are managing 3kw on a clear day but previously used to get a solid 3.6kw, as there is actually 4kw of panels up there.

the warranty on the panels is 25 year linear performance warranty and 10 year product warranty. so someone needs to step up.

 
also just checked the installer warranty:

All Solar PV installations are subject to a full 10 year installers warranty from the date of commissioning.

so if they are leaking im guessing they will need to replace them.

i do wonder if those marks are just smoke from my neighbors log burner? as every panel is marked in the same corner and the wind blows towards the panels from the west which would drive smoke and water into that corner as the panels are south facing.

The unfortunate thing is that a guarantee in some instances is only valid for the companies trading life unless they've used a broker or holding company.

Also check online to see if the manufacturer's name cross references with a receiver or bankruptcy case

the installers still in business and there guarantee is 10 years so would claim on them i guess.
