This is one specifically made by Battery Tender - not necessarily looking to quickly charge, but rather keeping the battery topped up while it sits outside.
So far so good, as I have yet to have any issues.
If I did it again, I'd probably go with the 10 watt panel, only because it's a little smaller dimensionally - the 15w panel fits, but with slight modification.
Solar sunroofs should be a standard option on battery sucking BMWs.
