11 different experiments allow players to create their favorite models.
Children can have fun and learn the basics of solar power.
It’s also educational for children to learn the gear ratio by different working speeds and power from the models.
The patented solar power pack included, consists of a solar panel, a motor and a gear speed reducer which can transform solar power into electricity and then drive the model.
Apply the solar panel vertically to the models and it will still work fantastically.
