Solar PV Comparative Efficiencies by Photon Labs

Comparison on the electrical production of Photovoltaic solar panels:



Here is the official publication of these photovoltaic tests and tests

Yeah, it's edifying and the Sanyo panel takes full g ...

But too bad the sample is so small: there are so many manufacturers.
What is nice is that it is finally a test where we meet the notion of KWh / KWc.
what i love is (i quote and translate) "... then the real power of the 3 specimens bought by our team is substantially below the rated power. It's like we bought a second batch choice ... "(bottom of the page and beginning of the 2nd)

Ben the diagram results is still misleading because it seems that there is 30 40% difference between Photowatt and sanyo while there is only 10% ... The zero being 750 ...

Effectively.

What would be really interesting - but infeasible: the "durability" of the panels.

As much as I see that there is hardly any difference in performance, I can imagine that depending on the quality of the assemblies and the materials, the panels can last from single to double ... But they "pay" after 10/12 years !

Hello !

I happen to come across your exchanges.

For me, the performance criterion is not useful to me (unless I lack space)

The indicator € / kWh (net purchase all inclusive / NRJ produced) gives me much more information, with of course the lifetime (on this, the guarantees on 10, 20 or even 25ans, especially for PV, are fairly representative )
