- 2. Abstract A maximum power point tracker (or MPPT) is a high efficiency system that extracts the maximum power output from a solar cell or array of photovoltaic (PV) cells. PV cells have a single operating point where the values of the current (I) and Voltage (V) of the cell result in a maximum power output. Maximum power point trackers utilize various type of control circuit or logic to search for this point and thus to allow the converter circuit to extract the maximum power available from a cell. In this project the Incremental Conductance algorithm will be used for the MPPT.
- 3. EXISTING SYSTEM There is no existing system for a MAXIMUM POWER POINT TRACKING to extract the unique power from the solar panel at this requirement.
- 4. Proposed system In the proposed system ,the maximum power is tracked from one or more photovoltaic devices so that the power transfer is efficient. It Shifts the array operating point away from the peak power point until production exactly matches demand.

- 7. Arduino IDE Arduino IDE is used for programming the Arduino board. The programming language used is Embedded C. Arduino IDE is a free software. Testing and debugging of programs can be done by using the Arduino IDE software.
- 8. EAGLE – PCB Design EAGLE (easily applicable graphical layout editor) is used for PCB design. Maximum drawing area 1.6 x 1.6m (64 x 64 inch). Resolution 1/10,000mm (0.1 micron). Up to 16 signal layers. Conventional and SMT parts. Comes with a full set of part libraries. Easily create your own parts with the fully integrated library editor.
- 9. OrCAD – Schematic Design OrCAD is an EDA (Electronic Design Automation) software. OrCAD Capture is used for drawing circuit diagrams (Schematic Design). It has in-built libraries for various components used in the project. OrCAD is an easy to use circuit designing software.
- 10. LabVIEW LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical programming environment used to develop measurement, test, and control systems using graphical icons and wires that resemble flowcharts. Using LabVIEW real time signals from various sensors and devices can be seen as continuous graphs and waveforms. It is an easy to use software and does not require any experience in conventional programming languages. Instruments similar to real life instruments and even more complicated interfaces can also be implemented easily.

- 12. Arduino Board Arduino is a single-board microcontroller, intended to make the application of interactive objects or environments more accessible. Pre-programmed into the on-board microcontroller chip is a boot loader that allows uploading programs into the microcontroller memory without needing a chip (device) programmer.
- 13. Features of the Arduino Board It is an open source embedded system. It has the Atmega168 microcontroller. The operating voltage is as low as 5V. Maximum clock frequency is 16MHz. Embedded C is used for programming the microcontroller with the help of the Arduino IDE software. It can communicate with computers, other Arduino boards, or other microcontrollers. It can be used for almost any real-time application.
- 14. Solar Cell A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell, whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are combined to build solar panels.
