I was asked to put together a setup to keep the batteries on a camper charged without having to plug into the grid or burn fuel.
We found this real nice 45 watt kit on ebay for a good price. Much cheaper than buying three of the 15w panels I have (at $80 each). Plus it comes with two 12v compact fluorescents, a charge controller, and a light duty stand to set the panels up with if you choose.
For this purpose the stand will likely be scrapped and we will set up something more practical for sett....
