The tool is designed for observation of changes in solar energy into mechanical energy, sound energy and light energy. A solar cell panels mounted on a holder that can be adjusted on a single axis to direct it to the light source. Some components such as electric motors, buzzer, light bulb is included in this set of tools.

This apparatus is equipped with a voltmeter to measure the voltage and ampere meter to measure electric current generated by the solar cells. There are 4 mm as a terminal connectors and equipped with connecting cables.
