Mechatronics Technology for Solar Cells

A mechatronic real-time solar tracker is developed with National Instruments Compact Rio programming module, photoresistors sensor, stepper motors, and a set of nickel metal hydride (NiMH) cells. The tracking array is able to pivot on two axes by way of the stepper motors to reflect the effect of daily and seasonal trajectories of the sun. This design will keep the solar cell perpendicular to the sunlight. This project furthers the application of mechatronics to the field of renewable energy.

The Right

The research was conducted to explain how to design a simulation of Solar tracker on Wind-Solar hybrid technology. The simulation were carried out with proteus software simulation. Solar tracker has four LDR sensors and an Arduino Uno Microcontroller which assist the Solar tracker to estimating position of the sun to use a servo motor for solar cell movement. For the result, When the upper light intensity (LDR 1 and LDR 2) is greater than the bottom (LDR 3 and LDR 4), solar cell will move upwards, and vice versa. When the light intensity of the left (LDR 1 and LDR 3) is greater than the right (LDR 2 and LDR 4), solar cell will move to the left, and vice versa. From the research, it could concluded that Solar Tracker can be applied to Wind-Solar technology solar cells

The Difference ◽

Cost Efficient

Solar cells known so far still have many shortcomings in terms of Mounting and positioning against the sun, so the performance of solar cells in Battery charging is not maximal. There fore additional tools are required As a support for the solar cell to work optimally, and the electric current Is generated larger. Sunlight tracking with LDR system as As the sensor to direct to the sunlight rays will be compared With a passive system. Atmega16 as motor control and auto carger, LDR As a recipient of sunlight, DC motor as a direction player Sunlight. Solar cell is used with a capacity of 20 WP.And auto carger system using microcontroller is more cost-efficient and installation. After the two systems will be compared first in order Know the difference how much power generated by solar system Cell using a tracker and a passive one. Data retrieval will be Implemented for one week with sytem tracker and one week with Passive system. With the results of data to be in can be analyzed system comparison And known how much efficiency. Expected with a solar tracker system Cell can increase battery charging faster than with Passive position.

Photovoltaic (PV) is one of the most important sources of renewable energy in the world. Its current efficiency could be increased up to 60% by using dual axes solar tracker, which maximise PV exposure to sun. The most important component in dual axes solar tracker is sensing location of the sun. Four light dependent resistors (LDR) are used as the sensors, connected to potentiometers to increase their accuracy. Arduino UNO is used as the controller to control two stepper motors. Two experiments have been carried out, where the tolerance of the LDR has been found to be 0.05V and the calibration of the four LDRs to have the error of 0.03V. Both experiments proved the capability of LDR for dual axes solar tracker and potentiometer to increase their accuracy.
