Solar Wild Boar is an ideal solar DIY kit for a do-it-yourself science fair, after-school,
or summer workshop project with the bonus of learning mechanical transmission
and solar power. With only 47 assembly parts, it’s a wonderful project for the
beginner enthusiast 8 years and up. Solar Wild Boar is an opportunity to have fun
while learning.

Place Tusk in the sunlight and tilt the solar panel so it faces directly into the sun.
The motor should start turning and Tusk will come to life. When you are not using
Tusk, keep it out of the sun so the motor won’t run. Also, don’t use Tusk outdoors
when it’s raining. If there is no sunlight, use a 50W halogen light bulb to simulate
the sun.
With adult supervision, shine the lamp approximately five inches from the solar
panel. The light should be enough to drive Tusk.
CAUTION: Do not shine the lamp on it more than three minutes as the heat may
melt the plastic frame.

Solar Power
Solar power: With energy costs and pollution rising, the limitless supply of pollution free
solar energy will have an ever-increasing role in meeting our world’s energy needs. Since the
sun will always be bright, solar energy will always be available. Solar panels are quiet, clean,
and will last for years since they don’t have any moving parts that can wear out. Although
electricity produced from solar panels is still several times as expensive as electricity
produced by normal energy sources, however that is changing as solar panels become less
expensive and more ecient. Scientists are constantly experimenting with new ways to
capture the energy radiated from the sun. More and more products are being developed that
use solar panels as their power source.
Sun power: The sun produces heat and light on an immense scale, by transforming
Hydrogen gas into Helium gas. This “transformation”is a thermonuclear reaction, similar to
the explosion of a Hydrogen bomb. The earth is protected from most of this heat and
radiation by being so far away, and by its atmosphere. But even here the sun still has power,
since it can power the motor in your kit and give you sunburn on a hot day.
Nearly all of the energy in any form on the surface of the earth originally came from the sun.
Plants get energy for growth from the sun using a process called photosynthesis. People and
animals get energy for growth by eating plants (and other animals). Fossil fuels such as oil
and coal that power most of our society are the decayed remains of plants from long ago.
These fuels exist in large but in limited quantity and are rapidly being consumed.
Born in the space program: The solar panel is a photo-voltaic cell, with photo meaning light,
and voltaic meaning that it produces electricity. Photo-voltaic cells were rst developed for
the space program to recharge batteries and power various systems in spacecraft and
satellites. Although they were expensive, they save money because heavier batteries or other
fuel sources did not have to be launched into earth’s orbit on very expensive rockets. The
sun’s brightness is reduced when it passes through the earth’s atmosphere, so solar cells are
more ecient in space.
Solar cells are used to power most satellites because they are lightweight and never wear out
(sending a serviceman to do maintenance on a satellite is extremely expensive). Over the
years, manufacturing processes for photo-voltaic cells have improved and have reduced in
costs, and now they are used in many common products on earth such as calculators, and
often charge batteries in industrial applications. It is likely that a large portion of America’s
electricity will be produced from solar cells by the end of this century.

Your solar panel is made from silicon, like the transistors and microprocessor used throughout the
electronics industry. Silicon is easy to nd, since ordinary sand contains mostly silicon.
The silicon is rened into two layers of very pure crystal, but tiny amounts of dierent minerals
(such as Boron and Phosphorus) are added to give one side a positive electrical charge and the
other side a negative charge. These opposite charges cancel each other out, producing a neutral
cell. However, when sunlight shines on the silicon crystal, charged particles in the light unbalance
the cell and create an electrical charge across it (called a voltage). By connecting wires to the
positive and negative layers, this voltage will make a ow of electrical charge, called an electric
current.
Solar cells operate best when bright sunlight is always available. Unfortunately, most areas of the
United States only get about 4-5 hours of sunlight per day on average. The electricity needs of
people vary throughout the day, whether or not the sun is shining. Because of this, most solar cell
arrays are used to charge rechargeable batteries. The batteries provide for people’s electricity needs
throughout the day and are recharged whenever the sun shines. Solar power is often used in
remote desert areas, because it is too expensive to build electricity distribution networks to them.
