This kit is to demonstrate the concept of conversion of solar energy to wind energy to electric energy. Keep the solar panel only in full sunlight and solar fan, dynamo in shaded area. Connect the wires to the solar fan, this energizes fan motor and couple this fan with dynamo motor (generator) thus air strikes the dynamo blade, it turns the coil of small generator to produces electricity by induced e.m.f. and lights up the LEDs and which indicates the current being produced by the generator.
