Home Made Maximum Power Point Tracking (MPPT) Charge Controller by Using Arduino

What is Mppt ( Maximum power point tracking)?

We use MPPT algorithm to Extract the maximum available power from the Photovoltaic module under certain conditions. MPPT is a Most Popular tool that helps us to use Solar Energy (Renewable Energy Source) in an efficient way. If we want to Reduce the Graph of Carbon footprints then we must need to move towards clean Energy which is called Renewable Energy ( Energy we can get from Natural resources) Like SOLAR, HYDRO, WIND e.t.c otherwise we will directly move toward Global Warming. Every Country needs to Move towards the Green Energy especially the CHINA because it is the Main contributor by producing 63% Co2 | Alternative energy.


How MPPT works? Why 150W solar panel does not equal to 150 w?

For example, you bought a new solar panel from the market which can deliver 7 amps current, under charge the setting of a battery is configured to 12 volts: 7 amps times 12 volts = 84w (P=V*I) You lost over 66 watts – but you paid for 150 watts. That 66 watt is not going anywhere, but it,s due to the poor match of the solar output current and battery voltage.
After using MPPT algorithm we can get the Maximum available power Battery gets is now 12 amps at 12 volts Output power is equal to p= V*I p=12*12=144w Now you still have almost 144 watts, and everyone is happy.

Step 1:

Libraries Required For Arduino IDE

Update Your Arduino Libraries first before going to the hardware side 

Remember: Make a New Folder ( Folder name should be same as library names like TimerOne and LiquidCrystal_I2C. Paste these Two Folders in Arduino/LIbrary.

Step 2:

Model of Arduino Based MPPT Algorithm and Proteus simulation of the Project

This Simulation has been designed in Proteus Software 8.6 version. You can make your own by usingArduino Library for Proteus and a simulation tool is known as Proteus. Kindly Contact Us if you want to Buya proteus simulation source file for this project. 

Step 3:

WiFi Data Logging by using a Wifi module ESP8266

Read This Article: Learn How to Setup the Wifi Module ESP8266 by Using Just Arduino IDE

After Reading The Above article I am assuming that you have successfully connected your ESP8266 module to your Wifi. 
  •  Go and Sign Up in https://thingspeak.com/
  • Make a New Channel and write “Solar Panel Data” in Field 1 and leave other fields blanks and save it. 
  • You will Get API key, Copy that Api Key and Paste in Source Code.
  • Done

Step 4:
