There were actually several versions of them as I recall. I know that I have 
seen 34 watt, 39 watt, 43 watt (seemed to be the most common), and some 48 
watt. I think the 48 watt were designated M53, not M51 like most. Quite a 
few were also the 16-2000 model. Most were similar, some were just 
variations on the type of junction box or wiring.

Pretty easy figure it out if you have the panels, just measure the short 
circuit current and subtract around 10%.

They came also in different versions of being "cooked" - the Gold were the 
least fried from the concentrators and were a light brown, don't recall the 
other versions.

It has been many many years since I fooled with any of those, so have 
forgotten a lot of the details and I could be wrong on the exact Arco model 
numbers.
