11. There is also a transparent plastic body sheet provided in this kit that you can use to make a body
shell. Fold the plastic sheet along the edges as diagram.
12. Fit one side of the plastic cover onto the pins on one side of the chassis. Bend the cover over and fit
the other side onto the pins on the opposite side of the chassis. Why not stick some your favorite stickers
on the body to make your Solar Rover look cool.
Congratulations! Your Solar Rover is ready to go.
D. OPERATION
Put your Solar Rover in the sunshine. Twist and tilt the solar panel so that the panel faces the Sun. This
allows the panel to collect as much sunlight as possible. Adjust the reflectors so that they reflect
sunshine onto the solar panel. The motor should start running, making the Solar Rover move forwards.
When you are not using your Solar Rover, keep it out of the sunshine so that the motor doesn't operate.
Don't use the Solar Rover outdoors when it is raining as water may damage the solar panel and motor.
You may also use the Solar Rover indoors or at an indoor school
science fair. Ask an adult for a desk lamp with a 60-watt
incandescent light bulb (not a fluorescent energy saving bulb). The
bulb will act as a simulated Sun. Shine the lamp close directly onto
the solar panel from close up. The light should be enough to drive the
Solar Rover. Warning: An adult's permission and supervision is
required when using a desk lamp.
E. TROUBLESHOOTING
11
If your solar rover does not move:
• Check that the bare wires from the solar panel and the motor are touching their terminal caps.
• The floor surface may be too rough or uneven. A rough surface will create friction which affects the
performance of your Rover.
• Try giving the Solar Rover a gentle push to get it started.
• The sunlight may not be strong enough. Adjust the angle of the panel so that it faces directly at the Sun.
If it's cloudy you may have to wait until a sunnier day.
• Check that the gears are lubricated. Friction between the gear wheels will affect the performance of the
motor.
12
If your solar rover runs backwards:
• The wires from the solar panel are in the wrong terminals. Swap them over (but keep the wires from the
motor in the same terminals).
F. HOW YOUR SOLAR ROVER WORKS
The solar panel is made up of solar cells. When sunlight hits the solar cells, the cells create an electric
current. The current makes the motor turn, which turns the wheels. The gears make the wheels turn more
slowly than the motor. This allows the motor to turn the wheels more easily.
G. FUN FACTS
• Energy we get from the Sun is called solar energy. It's a renewable form of energy because the Sun keeps
shining all the time.
• Only about one billionth (a thousandth of a millionth) of the energy the Sun gives out hits the Earth.
• When light hits a solar cell, the solar cell works like a battery. In the Solar Rover, it pushes electricity
through the motor.
• Solar cells are made from a material called silicon. Most silicon used to make them comes from sand.
• We use solar cells to make electricity in all sorts of gadgets, from watches to garden lights.
• Experimental solar vehicles work just like Solar Rover. They have roofs made from solar panels that
provide electricity to work their electric motors.
• In 2007 and 2008 Solartaxi drove right around the world just using its solar panels. It also used it solar
panels to recharge its batteries.
• NASA's robot rovers called Spirit and Opportunity drive across the surface of Mars using electricity from
solar cells.

Place your Solar Rover outdoors on a sunny day and watch it zip along. No batteries are required —the
Solar Rover's solar panel turns sunlight into the electricity that runs the motor. Recycle a soda can to make
your Solar Rover unique. It's a science project that's green as well as fun!
