Feature: 1. Solar Energy into Electrical Energy: Aim the solar demonstrator battery at direct sunlight (or close to an incandescent light of more than 60W). Connected to the voltmeter at both ends, you can see that the solar cell has a voltage output, light energy is converted into electricity, with a hand to cover up the light, you can see the output voltage changes, indicating that the strength of light and how much is converted into electrical energy relationship. 2. Drive the Music Sounder: Music sound plugin socket and the two ends of the solar cell positive and negative poles should be connected, the battery panel aligned with direct sunlight (or close to the 60W incandescent light), you can hear the speakers to send out pleasant music. 3. Drive Motor with Solar Battery: Connect the socket of the motor plugin to the ends of the solar cell, and the battery panel to direct sunlight (or near the incandescent light above 60W), you can see the motor rotate. 4. Durable Construction: Experimental energy conversion kit is made of premium material, which is hardness, not easy to deform, sturdy and durable and has a long service life. 5. Easy Operation: Solar cell device experiment equipment is used to demonstrate the conversion of solar energy into electrical energy. Simple to operate, intuitive, interesting and so on.
