Claim:

Cell size:  62.5" x 32.5" = 2031.3 sq in = 1.31 sq m

2800 W / 1.31 sq m = 2137.4 W/m^2


(1) Standard Test Conditions (STC) of 1000 Watts per square meter
irradiance, air mass of 1.5, 25oC cell temperature used in lab  
testing and
rating of photovoltaic modules.


Performance:  Pout/Pin =>  (2137.4 W/m^2) / (1000 W/m^2) => 214 % eff.

Remarkable!!

Yup.  I already remarked on it in fact, that FreEnergy can't do the  
basic math, thus proving your point that it is indeed remarkable, but  
my English aren't going that can happen so good.  8^)

I just received a Power Point Presentation from FreEnergy. They  
claim to have a new solar technology called MEL. It is said to be  
70% efficient. Existing solar cells are 17% efficient. They say  
that their cells will be cheaper too. A 62" X 32" panel is  
supposed to produce 3 KW.


Can't do basic math I would guess.  That's over 200% efficient.   
Only way that's going that can happen is if the cell is illuminated  
by reflectors, thus increasing the "size".
