Congratulations, you have just purchased a very unique solar powered model. In the age of

rising energy costs, the idea of a free and virtually limitless energy source seems too good to

be true. For years scientists have experimented with various methods of capturing the abundant

energy radiated from our sun. Today, although far from perfected, solar technology has been

advanced to a point where we have learned how to harness and utilize the sun’s power. Time,

research and money will bring to the market place new products that will be energy savers

needed by the entire world. Your Solar model is designed to demonstrate the potential of solar

energy. We hope that you will enjoy and educate others regarding this energy source of the

future.

SPACE AGE TECHNOLOGY

Your Solar model is powered by means of a tiny disc which actually converts light into

electricity. This disc, more commonly referred to as a photovoltaic (photo meaning light and

voltaic meaning producing electricity) or solar cell, is the result of the extensive research and

development which went into the space program. Scientists originally developed photovoltaic

cells as a means of recharging batteries and powering various systems contained in spacecraft.

These tiny cells have contributed greatly to the success of the space program.

Research and development of solar cells increased on a fairly large scale. Cost was not the

big factor weight was the big factor, even the critical factor. Every additional ounce put into

orbit had to be carefully considered. The efficiency of solar cells increased and manufacturing

techniques improved. Solar cells become lighter and less expensive. In many cases, batteries

could be eliminated completely and solar cells used to supply all the electrical power required

to operate the equipment aboard satellites. This research has helped to open the door to the

unlimited potential for applying solar technology to industry and to our private lives.

CARE AND MAINTENANCE OF SOLAR CELLS

Though it may be hard to believe, these lightweight solar cells never wear out or require any

maintenance. Do not drop or abuse the solar cell or solar cell module, as the material it is made

from is similar to glass and will break. We are not responsible for solar cells which are damaged

due to mishandling. The motor provided with your Solar model requires no maintenance and

its operation should exceed the models lifetime.

To clean, a simple blowing with your breath removes dust and most foreign objects. We

recommend wiping with a soft cloth and glass cleaner.

HOW DO SOLAR CELLS WORK?

Most of the solar cells in volume production today are made with silicon. This plentiful natural

resource makes up more than one fourth of the earth’s crust and is the chief component of

ordinary sand. The silicon used in the production of solar cells must be purified to a very high

degree. A large part of the cost of solar cell production results from the painstaking task of

removing all but the slightest traces of impurities in order to produce the highest quality silicon.

To make the solar cell which powers your Solar model, we start with a thin disc of almost

pure silicon crystal. When the silicon crystal is being formed, a small amount of boron is added.

The boron gives the crystal structure a unique characteristic. It actually has a positive electrical

charge. Since this part of the solar cell has a positive charge it is referred to as “P” type silicon

and it forms the base of the cell.

Next, a very thin layer of silicon crystal is formed over the disc of “P” type silicon. However,

instead of adding boron, this time a small amount of phosphorous is added to the mixture. The

phosphorous provides a negative charge and thus is referred to as “N” type silicon.
