Solar Panels?

Hey guys, I have some questions about this particular scenario. I've got quite a few of these VW car solar panels. They use them at dealerships to keep the cars batteries fresh. If I had 4 of these running parallel to a controller then to the battery bank, do you think it would help much? How fast would it charge? I've just started reading the 12volt Bible so be easy on me...

Here are the specs:

Elec. Ratings at 1000 W/m squared, AM1.5, Cell Temp. 25 degrees Celcius

Max. Power: 3.2 W
Voltage at max. power: 18.8 V
Current at max. power: 170 mA

It looks like this gentleman figured it out as well... First 235 Tips: VW Solar Panel for Battery Upkeep
