Contamination under glass? (PV panels) - Page 3

I think the contamination(?) that's causing the darkening of the existing marks and forming new marks,
Is worsening because of the chemical reaction activity, and the sun is likely a catalyst.

I'll bet there are more new marks formed during the summer of 2012..
I plan to re-test each panel this spring. If the power is down, I might
have a warranty issue..

So i can understand from your email that you didn't note a specific power output deterioration. Is it correct? Ciao.

I have not tested them individually since they were installed.
But, they seem to be working very well, keeping my backup system fully charged
and able provide around 400watts of excess power, while maintaining the battery bank charge.

Maybe spring, I'll use my new Turnigy meter and resistive loads to check each panel, on a nice sunny day.

dear sir XRINGER
Thanks for the scheme
I built two pieces of solar traking
works but I have a little problem
How do I connect switches
of acttuator
If you do not mind to help me with this problem
thank you

dear Xringer.. can you please tell me when you grid-connected the "contaminated" modules ? another question about the area in which the modules are operating... is it a particularly windy area ?
tks a lot.
