Set of Solar Energy
A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. This set demonstrates the principle of solar power. The electric motor starts working by connecting to solar cell, electrical energy converts to mechanical energy. This product consists of a solar panel (6.5cm*9.5cm), an electromotor, a propeller and stand (optional).
