My little girl just keeps getting bigger, and she’s almost the right size for a Power Wheels ride on toy. A while back I got one for free – it didn’t have a battery or charger, so it didn’t run.
I also had a Harbor Freight 45-watt solar panel kit. It dawned on me that the solar panels are really just a battery charger, and almost the exact right size for charging a used battery I had AND making a great roof for the car.
That’s all the motivation that I needed to put together the solar panels on a custom rack and attach it to the Power Wheels Jeep. When done, the entire vehicle will be completely solar powered!
Of course the real question is how does the kid like it!? Here’s a video of her driving around the finished solar-powered vehicle.
I also have a full “how-to” write up on the project at Instructables.
