Solar and Watt crest, an unknown unit ??

[jezy]

I just saw a unit that I did not know the Wc / m² for the measurements concerning the performance of the silicon cells of a solar panel. Apparently it's a watt peak but what does that mean ???

If I am not mistaken, in solar it is the maximum power that a photovoltaic panel can give for a "normalized" radiation (ie under artificial radiation around 1000 Watts per m²).
