There are a few things you need in order to build a solar powered rc car. The first is a solar panel, which can be bought online or at a local store. The second is an RC car, which you will need to buy or rent. The third is some wire, solder, and some tools. The fourth is the battery, which you will need to buy or rent. Finally, you will need some screws and nails to attach the solar panel to the rc car. Once all of these things are in place, you can start building your rc car!
