    Ok, here's a complately crazy, out-there idea. Get another battery or two, and whilst you are discharging one you can be charging the others. Then when it gets flat just swap them over.

    Solar aint never gonna work. Give up...! Or keep entertaining us, your choice.

    You know, one problem with using solar that we haven't mentioned yet is the problem it might cause with your radio. Since the electricity that comes from sunlight moves at the speed of light (instead of the electricity from batteries, which moves much slower) it runs the circuits at a different speed, include the crystal that handles the radio frequency for your R/C unit.

    Solar works in other things because there's a person at the controls, but you might have to buy all new crystals of different frequency ranges to be able to use the higher speed solar electrons.

    Also, solar electrons are much stickier than battery electrons, so you'd need to put in one of those electrical lint traps (they're the little metal things in plastic you see on phone cords and stuff) and keep it clean by running a magnetized pipe cleaner through it every day.

    It's best that you follow Mr. Withey's advice and get an extra battery.

    Isn't this the same guy who wanted to fit an alternator to his RC car?

    No no, he wanted to fit an 'autonator' to his car, which is a non-Newtonian device unaffected by the limitations of the laws of thermodynamics. Pretty straight forward, but finding enough unobtanium wire to wind the coils is difficult, and the Heisenberg-compensating rectifiers are terribly expensive.

    yes i cant spell.
    but will this work?

    how much would a battery that has 1500 mA and will last around 7 mins take for mA for a solar panel?

    i need to know that to get one also!

    thank you for all ur help.

    or i can make my own so the size wont matter as much any help on either?

    OMFG you cannot be serious...

    As entertaining as this thread is, I think we need to stop this before any more solar panels start to produce light and such.

    @OP: No it is not possible. You cannot generate that much power with a solar panel that size to do anything but light up an led really. That is why when you get a solar panel, there are huge arrays of them and they produce diddly squat.

    Perhaps a mobile fully enclosed nuclear generator is in order. And you wont need the battery then (or have room for it, that is where the coolant will have to go)

    That was MY idea!

    Just do this:

    - Get the largest capacity batteries out there that fit the size (1500 isn't much)
    - Get a GOOD charger (an intelligent one) that keeps the batteries in optimum condition
    - Use one battery pack while you charge the others

    If you used google and half your brain, you would have found that solar panels need to be very big for a small amount of power, just like you would have found that the energy needed to spin an alternator requires more electricity than it will generate...

    If you don't want to look dumb, you better look up some stuff before asking random questions.

    Good luck with the car - it's a fun hobby and you will learn a lot from it if you keep looking for improvements, just don't let this old git's rant discourage you

    I'll attempt to answer this dudes question.

    "How would solar panels to charge"??? Are you asking, how long would it take solar panels to charge a battery of 1500mAH capacity at 7.2 volts that fits into 2 by 3 inches? Most solar cells are 0.5 volts. You can get some that are amorphous silicon built on a glass substrate that have a higher voltage. You'll be lucky if you get half a watt in that amount space. So if your question is really "how long would it take a solar cell that fits into 2" by 3" that charges a 7.2 volt battery, it would be .5 watts/ 7.2 volts = 70 mili-amps. Assuming your charging a 1500 mili-amp hour battery, then 1500/70 = 21 hours of good sunlight.

    can only be around 2" by 3" or 3 1/2"

    i'm looking for this to help power my rc car (1/18 scale).
    There are 6 batteries to power the motor and i need it to help so i dont have to keep charging the battery and the solar panel can just charge it for me then.

    Someone help me with this?
    websites.
    Ideas.
    Anything.
    If it will work?

    Just please help me

    what if i made my own solar panel would that help?

    any websites u can help me with to find that?
