Picture of Solar powered electric car
After converting 1995 Aspire to electric vehicle ,I decided to go 1 step further. I installed 6 solar panels on garage roof , with batteries and inverter in garage. Car charges during the day and I drive it on after work missions. Works great driving around town (usually only 5-10 mile trips) will go 55 mph. If it is cloudy a few hours charging continues due to batteries in garage.

Step 1: Remove engine

Picture of Remove engine
First step is removal of engine and components, radiator , tailpipe , muffler ,etc

this makes me miss my 86 Subaru that was converted. It finally was too difficult to continue to repair (rusted out).

How did you get your hands on a motor like that, I've been looking for a long time but never found anything

You could use a golf-cart motor, or possibly a starter motor from a pickup truck or other large vehicle.

How do you get it passed state inspection? When you convert the car, do you need license plate and automobile insurance?

kindly mail me in brief means which motor shall i used and list of components which i can buy here in pakistan to manufacture these and explore more about it knidly mail me?

I want to make a car..solar based...
plz mail details about its components ..design..and all other things...plzzzz. ..

Great instructable. You could have a hydroelectric generator going 24/7 to power it. 12 motors acting as water wheels then use a DC to DC boosting circuit to get them to 10V each. 10 x 12 = 120V. You could then charge the batteries. 24/7 power and you wouldn't need as any batteries because it would run continuously therefore you wouldn't need as much voltage or motors. Let me know what you think of it, if there are any flaws and any ways to improve it. Thanks.

What's your optimal RPM for your motor? I have a differential with a 1:3.5 ratio that I'm considering mounting a motor on, but not sure if I should hook it up with a transmission in between.

a job well done! a true, pure home made Electric car. why don't you use one of the batteries 12v for headlights rather than 72v to 12v converter? also please think about putting Solar panels on roof and hood. those 100w something may improve driveability of the car!
Frankly.. I think this is a great project. Might change the batteries, voltage & motor a little.. But all else for me is on project ! I'm building a high horsepower for drag racing. Hoping to have a car that will certainly turn some heads and not thinking they have a category for electric cars yet t soul .
please can i hav the complete explanation for this electric car this is my email (georgekaycares@gmail.com)
How many total miles can you go off of one charge?
50... i think.... i would think...idk

You could try putting vents at the top of the bonnet (Windsheild end) to help the air flow freely through and reduce drag.

I don't know if it will work but could be worth trying :)
Where in IL are you? I'm in Buffalo Grove, and would love to see the car someday if you're not too far away! Regards, Steve
Yes, I too am in IL and wondering how far away from you I am. Also wondering if you do conversions for other, mechanically challenged people? And you total costs? I am very impressed!! Good job!
Awesome job. I've been wanting to go electric with and old beetle for a while now. I hope to have the success that you have.

Actually I was looking for an old beetle , before I found this Aspire , If I remember its a little lighter (and I wouldn't have to wear a seat belt) .I'm sure that someone has already figured out mounting motor and other tricks if you search online.
Why ruin a valuable car like an older VW. If it is old enough to not require a seat belt, It is an extremely valuable VW. It would make more sense to restore the Beetle and sell it. There should be enough cash to buy a new electric car if you wanted.

It seems Tesla is also taking this convert a gas car (Lotus) to electric and add solar panels to the garage roof. The better solution is found at Stinger Motors Inc.
Your Car is awesome and gives us great hope for having our own electric cars and the video I posted shows this guy with an electric car beating high class sports cars and using smaller batteries. :)

Have you thought about mounting the solar panels on top of the car?

Great project.!
I though about making a conversion myself, however; I live in Costa Rica and hill are steep here, I assume battery life would not last the typical 40-60 miles. I have a question:  Sorry if it sound "dumb", can a small generator be attached to the car, in order to "boost" the energy going up hill, and charge batteries on a long trip. I understand it defeats the purpose of going "electric", however; is a though for "emergency" boost.
Thank you

Is something like this street legal? or did you have to get this approved with the government before you could drive it on the street?

What kind of speed and distance do you get out of the car? I was looking into a conversion kit but it only went 60-75 miles per charge and took 8 hours to charge the batteries.
mrmusty (author)  rommel5436 years ago
Car will go 55 (but will cut range down) . Driving to work is about 25 mile round trip at 30-40 mph and a few miles on interstate at 55. Thats as far as I really want to discharge batts . But on a warm day at 30 mph I'm sure it would do better. Temps below 30-40 degrees slow you down. With my solar setup I am sometimes affected by cloudy weather. I used 9 - 8 volt batteries ,if you used 12 -6 volt batteries you could get more range. Maybe with a small pickup and a whole bunch of batteries you could get 60 - 75 miles per charge. You may have to move up to higher tech batteries !
If ur car ran on 48V, you could use a couple of 48V LiFePo batteries, which have a vary high energy to weight ratio.
How does lower temperature slow you down? I thought electricity conducts better at low temperatures. Or perhaps you're talking about something else...
mrmusty (author)  guitarman63mm6 years ago
Yes the wiring has less resistance but the lead acid batteries lose quite a bit of power when they get cold , maybe 50% when its below zero. Also grease in wheel bearings and transaxle gets thicker.
you are correct with the temperature situation about the circuits, but batteries like the temp just right, not too hot, not too cold
how many voltage is the electric motor?

You can check out http://www.diyelectriccar.com for all kind of information about conversions.

I like the plan, food for thought here>> how about mounting a fan for a generator about were a trailer hitch would go( just under the rear bumper).

Nice to see your combat robot skills going to good use here! What are the amp-hour ratings on your batteries on both the car and the home station?
mrmusty (author)  muell2916 years ago
Yea gotta keep buildin stuff ! There are 9 - 8 volt 170 AH batteries in car and 8 - 6 volt 225 AH batteries wired up for 12 volts in garage.

What kind of motor did you use? It looks so dinky compared to the engine you removed. Could you give the specs on it? I'd like to know where I can get one.
mrmusty (author)  blksheep6 years ago
Its made by D and D Motors and has 40 peak hp. It measures 6.7" dia. x 12.28" long and weighs 62 lbs. Its a series motor and several ev conversion web sites sell them.

There has to a be a better way to charge the car off the solar battery pack. Converting from DC to 120V AC and then back to the DC in the car seems like a waste.
