This paper shows how the elevator door control motor, the ceiling fan and the LED lamp inside the elevator cabin are powered by solar energy instead of conventional electricity through an integrated system. The integrated system includes a solar charge controller connected to maintain a steady voltage into the induction type door motor, lamp and fan and also the shields the system against overcharging and over-discharging. The system has been implemented for AC voltage by using an inverter. The output DC voltage of the charge controller converted to AC voltage through an Inverter. Another important aspect of the project is that, currently the overall weight of the passengers inside the elevator cabin used to determine the overload condition of an elevator. One of the main goals of this project is to emphasize the overall weight as well as the total number of passengers inside the cabin at a particular time in order to understand the overload condition. The research incorporates a cost review as well to show the economic advantages that can be gained through the implementation of such an integrated system in the real world.
