I can offer u the solar cell. how much power do u want to buy?

Batteries for what? Your cell phone, then no problem.

To run the car? Is your car the size of a bus and the weight of a motorcycle? If not, no point in wasting your money. As a quick and dirty example, to attain the power of an average lawn mower (5HP or 3.7kW), you need approximately 600 square feet of a medium efficiency PV system. For a visual, the average 4 door sedan would be 160 square feet. Keep in mind that any motor power less than about 50HP is pretty much useless off of the golf course.So for a 50HP motor yu will need 6000 square feet of solar cell, larger than the average house in Los Angeles! Even if you could afford the best solar cells with twice the efficiency, you still need 3000 sq. ft.

Now, if it were a boat, that would be different. Boat users habitually use solar and wind capture to trickle-charge their domestic and starting batteries.

With a boat, the features are:

• Longer distances to, and frequent absences of, grid outlets
• Lower use/idle ratio compared to a car
• Higher surface-area-to-starting-power requirements compared to a car.

So for a car, trickle-charging the batteries might prove attractive, though for other reasons like low-use. The fuel saving is insignificant compared to the savings to be gained from adopting other operating factors, like:

• Correcting the tyre pressures at regular intervals
• Adopting wussy driving techniques, including driving significantly below the posted speed limit, where it can be done without delaying other vehciles, and partial slip-streaming behing larger vehicles
• Combining several tasks into one journey

and certainly could not be used as the basis for justifying an investment that will give an attractive payback.

Hello Cuyanausul

If you want to trickle charge your car battery, yes, such chargers are available easily.

Run your heavy vehicle from the solar cells, not at this time.

Perhaps another 10 years of Solar Cell and Fuel Cell development, and a car using four electric wheels, then it may be possible.

As for your present car, unless it is a toy one, no chance, sorry.

Kind Regards....

Thanks parkstation

Yea, I meant trickle, just to save some fuel
