One of the problems encountered when using solar cells to power DC motors is that although the cells can deliver the normal steady state DC current they have difficulty supplying the start-up DC current, which is typically 10 times the steady state current. Rather than specify a solar cell system that is 10 times larger than required for normal operation, a soft-start system is to be implemented. This system will use a solar cell array only 20% larger than that needed to provide the steady state DC current. A short term power storage system based on super-capacitors will be used to provide the much larger start-up current. The user will press a start button to indicate that the motor is to start. The solar system will then either use pre-store power or will rapidly collect power from the solar cells until there is sufficient to start the DC motor. The aim of this project is to design a soft-start system that has the minimum delay between pressing the start button and the DC motor achieving full operating speed.

So I want to know the circuit diagram and values of the components. Pls if anybody know about this let me know, thank you
