Sun I ight is now recognised as an important source of `alternative` energy, and the use of solar panels to convert the sun`s rays into electricity is becoming ever more widespread. For solar panels to operate at maxi-mum efficiency, however, it is important that the cells face squarely into the sun. Since the sun`s position is constantly changing (apologies to Messrs. Kepler and Galileo). it is thus necessary to employ a `solar tracker`, which will vary the orientation of the solar panel accordingly.
