Building the Frame
The frame is the foundation of any RC car and building it accurately is crucial to the success of the project. Below are some tips on building the frame:
| Materials Required | To Do |
|---|---|
| Metal rods or aluminum tubing | Measure and cut the rods or tubes to required lengths |
| Nuts, bolts, and washers | Secure the rods or tubes together using nuts, bolts and washers |
| Metal or plastic plates | Attach the plates to the frame to support the solar panel and other components |
Note: It is possible to buy pre-made frames for solar powered RC cars as well, but building one from scratch can be more rewarding and cheaper.
Interesting fact: The construction of the frame depends on the type of RC car, and it can differ significantly from car to car. A durable, lightweight and aerodynamic frame is the goal when building a solar powered RC car.
Don’t forget to wear protective equipment when working with metal cutting and welding tools such as goggles, gloves, and protective jackets.
There are many instructional videos and articles available to help with building the frame, such as the following:
Installing the Solar Panel
Proper installation of the solar panel is crucial for the efficiency of the car. Follow the steps mentioned below to get the most out of your solar panel:
- Choose the right direction to install the solar panel
- Use solid adhesive to attach the panel to the car (eg. Araldite, Gorilla glue or double-sided tape)
- Test the voltage of the solar panel before installing it to ensure it is in working condition
By testing the solar panel beforehand, it is possible to ensure the panel is outputting the correct voltage and current. Inaccurate performance may be caused by the wrong angle, improper connection, or even a damaged solar panel.
There are many options for where to purchase solar panels, but it is essential to buy high-quality panels that can deliver the most power. Below are some online websites where you can purchase solar panels:

How solar panels should be placed?
When installing solar panels, their placement is critical for optimal energy generation. Here are some factors to consider:
- Orientation: solar panels should face to the south in the northern hemisphere, and face to the north in the southern hemisphere, for maximum sunlight exposure.
- Angle: solar panels should be tilted at the angle that corresponds to the latitude of your location for maximum sun exposure.
- Shading: avoid placing the solar panels in areas with shading from trees, buildings or other obstructions that can interfere with sunlight exposure.
For more detailed information about solar panel placement, check out websites of solar panel manufacturers or suppliers such as SunPower or SolarWorld.
Assembling the Car
Now that you’ve built the frame and installed the solar panel, it’s time to assemble the car. Follow these steps to assemble your solar powered RC car:
- Mount the motor onto the frame
- Connect the battery to the motor
- Attach the controller to the battery and motor
- Connect the solar panel to the controller and battery
- Test the car’s performance to ensure all the components are functioning as expected
It’s essential to be careful when connecting the different electronic components to ensure proper and safe operation of the car. If you have no experience with electronics, it may be best to ask for help from someone more experienced.
In addition to the materials we’ve already discussed in previous sections, you may need additional materials for assembling your car, such as wires, connectors, and a charger. Below are some online websites that sell different components necessary for building solar powered RC cars:
