New Approach on Development a Dual Axis Solar Tracking Prototype

Good day mate ^__^

Last night was the first rain in Surabaya for the last 6 month (or so), and it made me, and maybe you all, wondering "is it real???" LOL

And that rain inspires me to present to you a good resume of a good paper. it is related to microcontroller for sure :)

this is all this...

eeeenjoooooy...

 New Approach on Development a Dual Axis Solar Tracking Prototype 

Author          : Nader Barsoum, Rinoe Nizam, Elvin Gerard
Title              : New Approach on Development a Dual Axis Solar Tracking Prototype
Source          : Wireless Engineering and Technology, 2016, 7, 1-11

Summary of Reported Research:
The authors made a solar panel that can track the sun's position in two directions, azimuth and elevation. In this paper, a dual axis tracking prototype is developed to catch the maximum sun rays by tracking the movement of the sun in 4 different directions. This paper presents extensive freedom of movement of the solar panel, by using Light Dependent Resistor (LDR). The authors were using AutoCAD software to design the draft of the system, and they were using SketchUp software to convert it to 3D model. In order to make the project cost-efficient, the authors were using Proteus software to design and to simulate the circuit of the system before they made the hardware. The brain of the system is Arduino UNO micro controller, and the system also uses H-Bridge IC chip.
First step to build the system was making the design model in AutoCAD software in 2D version then converted it in 3D by using SketchUp software. The hardware consists of several main parts :
  • LDR (4 ea)
  • DC motor (2 ea)
  • H-Bridge IC L293D (1 ea)
  • Arduino UNO (1 ea)
  • Solar panel (1 ea)
  • Board (as the base and the poles)
LDRs are used as the sensors of the system. Each LDR gives different resistance value, so the voltage value from each LDR branch can be processed by the Arduino to actuate the DC motor and move the solar panel until the solar panel is facing the sun perpendicularly.

Strength of Reported Invention:
  •  It has simple configuration, model, and circuit.
  • Speedy designing process, because the author used AutoCAD, Sketch Up, and Proteus software. Those software did help a lot.
  • The solar panel can be more effective on producing the electricity because the  solar panel will always be perpendicular to the sun.
Weakness of Reported Invention:
  • This solar tracker is only a prototype without using the real solar panel, so the weight of the hardware is not calculated.
  • The DC motor cannot point the angle in precisely (coarse).
