Solar Cells Are Getting Pretty Reasonable These Days

This years project is to add 8 more Home-made Solar Panels to compliment my existing system. That would bring me to a grand total of 25 panels. The issue with the design originally was that I greatly over sized the battery banks to which the panels and wind turbines could barely maintain the proper voltage and give it a good charging. I've noticed that the cells (Polycrystaline) made by Schott 4x4 are falling to under $2.00 per watt. From an auction posting on the Bay, LifestylePhoto has them by the 100 for $185.00 with tabs. I can vouch for this seller even though the not-so-great rating with applause since I've ordered from them before. They do sell what they describe. And of course my panels are around 7 months old without a hitch, still producing good even with the cold temps.

From this link, what's the maximum output of these cells ?

Is it 2 watts or are they using it as an average ?

Where do they get 4amps out of one cell ? If that was true I'd be getting 2448 amps from my array and it'd blow itself clear to the moon. I don't care for green cheese, either.
