If you need more material for handicrafts and experimentation or a classic kit for school, then this set should be your first choice. Thanks to the larger purchase quantity, you save 10% and benefit from the high quality at the fairest prices.
Technology:
The SM80L solar cell has an output of 0.5 V and supplies a generous 100 mA (max.). Of course, we only provide high-efficiency crystalline solar material, which is cast in a stable base plate. Therefore the shattering of the cells during installation can be ruled out. The SM80L solar cell has 2 soldering pads to which the solar motor can be directly soldered. Illustrated soldering instructions accompany the set and thus make the soldering very easy. With the proven RF300 solar motor, you can playfully set your model in motion. The solar motor and solar cell form an optimal combination providing the best functionality.
Contents of the set:
20 x SM80L solar cell with soldered connection, Dimensions: 45 x 25 mm
20 x RF 300 solar motor with 15 cm connection cable, 25 mm diameter, 2 mm shaft diameter, 10 mm shaft length, height without shaft: 14 mm
Weight of the set: 0,460
Tip from the Solar Professor:
Required lighting conditions: It should be taken into account that each solar cell generates very little current in dark or poorly lit rooms or from light sources like neon tubes and energy-saving lamps and, as a result, the motor cannot turn because the supplied power is too low. As soon as the sunlight radiates on the solar cell, it generates up to 100 mA current. Since the RF300 solar motor only requires 25 mA start-up current, there is sufficient current in reserve for lighter travel or rotational movement. It is unbelievable what this small solar cell can set in motion while in the sunlight.
