Tip from the solar professor: Required lighting conditions: One is anticipated, in dark or poorly lit rooms or with light sources such as neon tubes and energy-saving lamps, each solar cell generates very little electricity, the motor cannot start because the delivered power is too low. However, as soon as sunlight or halogen light illuminates the solar cell, the solar cell generates enough electricity for continuous movement. A model can also be operated with a strong flashlight, but the flashlight must then be very close to the solar cell! So better get out in the sun or a halogen lamp and there are already astonished looks and lasting insights.
