Introduction: Solar RC Car

A rc car with two solar panels strapped up top for charging power. (Sorry no images) video coming soon. This is my first Instructable so be as honest as you can be

Step 1: Scavenge the Parts

The first thing is to get the parts. You will need:

-Scavenged chargeable rc car (the bigger the better)
-two 12 volt solar panels (flexible is best)
-1-2 diodes (two if you recharge the controller battery)
-(optional) panel for controller that is close to its voltage
-(optional but recommended) old computer fan whatever size works

Tools:

-soldering iron
-solder
-wirestrippers
-duct tape

Step 2: Wire the Panels to Car

First is to pull the car apart. You need pull the body of the top of the car. Then find the positive and negative terminals of the pcb in the car. If there is a cover over the pcd drill holes to run wires through. Take the two 12 volt solar panels and solder wires on them (make sure you have enough to lay the solar panel next to the car with the cover of). Solder the diode on the positive terminal. Then run the wires through the holes and solder in them parallel to the diode and negative terminals. leave the cover of for the next step.

Step 3: Wire the Fan to the Car

This is simple. Wire this to either the positive and negative terminals on the rc car pcb or one of the solar panels. Close the car up.

Step 4: Wire the Controller

This is simple too. take the small solar panel. wire to long wires on the panel. Solder the wires to the terminals inside the controller. Make sure you drill wholes for the wires to come out of. Then your done.

Step 5: Driving

set up the panel, make sure the car was or is sitting in the sun and drive.

Which remote control car is better,solar panel or a electric battery car?

i am building a solar car too but my steps was a little bit diffrent but its cool

author

It's funny looking back on this now, and knowing what I do now about electronics vs. then, I'm a little shocked that I didn't hurt myself more often. ha ha.

im building a solar powerd car for a show at a elmentry school...any tips?
nice car by the way

keep all of the systems cool.

depends if its your first time with electronic components or you might have little experience and it might be hard

im also going to build a car thats solar powerd. would it be hard?

My solar powered electric trike actually has almost 1500 miles on it. The panels produce 15 watts at 24 volts. This will charge the batteries but will not run a 450watt motor. Hope that helps.

Fans for Cooling, things got very hot sitting in the sun, was afraid of the battery pack getting damaged

Why the fan?! What is the purpose ?!

author
heavydeath (author)2008-08-23

how did u run the energy straight in to the car u didnt use rechargeble batterys

author
starwarsfan (author)heavydeath2009-02-07

he probably just hooked it up to the motor with no batteries

author
frdmrckr (author)starwarsfan2010-07-10

The batteries were originally rechargable. I just threw a diode in and ran the solar panels to the same terminals the battery pluged into. It did charge them decently. That way if i did run into shade it still ran.

I guess i should have read this b4 i made my solar hummer. Its basically the same thing because neither of ours runs directly of solar.

author
frdmrckr (author)Mr.NHRA2010-07-25

well i also did run it without the batteries too. The batteries were a 9 volt rechargeable pack. The panel was 12 volts but the amperage was a little lower. it ran fine without them. Just the shade killed it...

the fan is for cooling down the engine but he or she should of not used it because it is a small car and im not sure if it would get heated that much but if im wrong fell fre to correct me

author
frdmrckr (author)handywomanparty2010-07-10

I used the fan to cool down the whole system. Sitting in the sun it got very hot and i was afraid of causing damage due to heat. its not needed

Great Idea! I'm going to try it with a frame rather than a whole car body. It might solve the speed issue. How much did your solar panels cost?

author

now solar panels are cheap

author
ReCreate (author)2muchfreetime2009-05-15

They can cost from 60 to several hundred dollars

author
frdmrckr (author)2muchfreetime2008-07-29

Free. They were donated to me from a friend

God bless your friend... I was going to do something like this but a bit more simple...

author
knight2067 (author)2008-08-22

Dangerous, but I might try with a r/c helicopter... Probably should keep the battery pack fully charged in case of cloud.

An RC helicopter Would not be able to hold it up,at all

Radioshack sells small superlight silicone panels that put out .5v. I'm gonna try to afix an RC copter  with some to trickle charge the battery in flight.

incredible instructable!
i have a school project to make one similar to this, and i was wonderingwhere you could get similar, cheap solar panels.
Thank you!

what is the size of the solar panel?

where i buy the solar panel

author
ReCreate (author)santi2009-05-15

You Can buy them somewhere for (If your really lucky) 60-300 bucks

what is the fan for?

Wasting Electricity,We don't want it to go faster than 0.00000001 MPH

gamefreek (author)2009-03-27

how fast dus it go. i bet is slow as hell

sorry, I don't get the comment on the far right in the first picture. I'm definately no spelling bee, but please can you at least proof read you're work? No hard feelings as its you're first

author
neardood (author)2008-08-22

I get the controller, but not the car.

is teh fan for charging?

Batteries don't like heat

author
Patrik (author)2008-05-19

Nice! Any idea how much juice the car needs, versus how much the solar panels provide? How long do you need to charge, vs. how long does it take to discharge? Will this actually move, running on just the solar panel?

author
frdmrckr (author)Patrik2008-05-20

The battery on the car is 9.6 volts. The panels put of 12 volts each and there both in parallel. It takes maybe about 15 to charge and runs close to 20 minutes. Yes it runs with just the panels but it tends to be slow and if it hits any shade it stops and I have to put it back in the shade
