Considering I bought a 300 watt flex panel for $65
That is walletgasmically cheap!

Assuming you could use all the energy, the effective sun hours you need to recoup your investement is:

Europe: 285
Hawaii/California: 577
Texas: 1024

And assuming $0.13/kWh at home we could lose this much of the potential energy and still be better off with the panel on the car than at home (assuming we are unable to plug the car in):

Europe: 83%
Hawaii/California: 65%
Texas: 38%

Of course there are more costs than just the panel, but that is also true at home.
