[RE-wrenches] Defective modules

OK any good data from outdoor tests showing energy produced by thin film
compared to crystalline in the same conditions would be most helpful.

 

Can anyone confirm that NERL tested Unisolar for long term degradation and
the results were not published.  is this a myth?

HI  Carl,

 

I can't seem to be able to get that data off the site.

 

Maybe someone else can.

 

It is a main reason I bought the subscription,  just to support their great
testing work.

Hi Jay,

 

Thanks for that, yes, I have seen the setup you refer to and it is very
comprehensive, but I thought that your reference to the 151 modules was a
lab test at STC and not an outdoor test for energy yield.

 

Can you send the link to the outdoor test results please.

 

Many Thanks,


Carl Emerson

 

Hi Carl,

 

Here is the link to how Photon measures each module.

and

Can you please tell me how they are doing it wrong, and what the test would
look like in doing it right?

 

Many thanks,

Jay,

 

The short answer is no.

 

These are not real world tests of energy yield under 'normal' outdoor
conditions.

 

Photon are setting up field tests for 2013 in Germany and the middle East.

 

Then they will have some useful data.

Hi Carl

 

Would like to see real data. 

 

Photon publishes their module data, and thin film are no where near the top
of the list. 

 

Nexpower. #14

First solar. #131

Total of 151 modules in the test.
