In the 1990s, emission laws were enforced in the United States, which resulted in many organizations, colleges, and universities looking for environmentally friendly approaches. Solar powered cars are a great way of conserving the environment.
In 2017, even online cab companies are changing the way they do business, and purchasing 100% 0 emissions electric cars. If you have a zest for coming up with a solar powered car on your own, following is a step-by-step tutorial specifically designed for amateurs who have never built a solar car before. But before you start, here are a few key things to keep in mind:
• Cost: You do not have to spend a fortune
• Weight: Heavy solar vehicles usually reduce the distance and speed so it is better to keep them light.
• Materials: You can improvise if you fail to find the exact material
• Runway or Track: You do not need a track but you can consider using a flat surface to operate your vehicle on.
Things You Will Need
• 2 solar cells and panels
• 2 1.5V AA batteries
• Electric hobby motor
• Fishing line
• Chop sticks or skewers
• Duct tape
• Lightweight recyclable materials
• Corrugated cardboard
• Alligator clip test leads
• Metal coat hangers
It is recommended you use recyclable material to build your solar powered car. The lighter the materials and frame, the better your car will use the energy.
1. Use a nail to create a hole in the center of the wheels. Ensure that the cop sticks or skewers you use for the axels fit in the holes properly.
2. Now, top off your chassis (material used for the car body) with the axles. Depending on the material of your chassis, you can string the axel via eye screws mounted on the bottom. Another simple way is to tape straws on the chassis’ underside and link the axels via them.
3. Connect the pulley with the motor shaft with the help of a drive belt or an elastic band. Place the motor in a way that the band becomes a little stretched. You can use glue or tape to mount the motor on cardboard blocks or a wood frame.
4. With transparent plastic tape, connect the two solar cells, one beside the other. Next, connect them in a series circuit with the help of the clip leads. Connect the negative terminal of one cell to the positive terminal of the other. Connect the rest of the terminals with the motor.
5. This is the final and trickiest part: connecting the wheels on your solar vehicle. You must install the pulleys at the same distance from each other or else your car will swerve right or left. Also make sure your pulleys are lined up correctly. You have installed gears. You must consider the gear ratio, parallel to the motor so you do not strip the motor’s internal gears.
6. Finally, mount the wheels after lubing them with WD-40 or graphite.
