What challenge/problem are you trying to solve through your application:
The development of renewable energy sources has been increasingly critical topic in 21st century with the growing energy crisis and environmental issues. The world is in great need of cost effective alternative source of electricity to cope with their ever increasing demands. Although photovoltaic cells and solar power extraction has been in the limelight since many years, but their cost effective utilization is still an explorable area with lots of research and development yet to be done. The goal of this project is to design a low cost user friendly solar power unit capable of utilising the maximum output from the panel.
How does your application solves the above mentioned challenge/problem:
Our project deals with a novel design of a Solar Charge Controller which would deploy the maximum power point tracking algorithm along with solar tracking to make the best use of the solar power available from the PV panels. The wireless Data Acquisition unit in the design transmits the reading of sensors as well as State of Charge to LABVIEW via bluetooth module which makes the system more user friendly.
Description of Project:
The project consists of following sub-systems:
1. Mechanical Tracking of Solar Panel: It is done by processing and manipulating the readings of 4 different LDR's by using LABVIEW and moving the servo motor so as to rotate the panel in the direction of the orientation of sun.
2. MPPT algorithm: It consists of a buck boost DC-DC converter through which the output voltage of the solar panel can controlled by varying the duty cycle at the gate pin of MOSFET so that the Li-ion battery which we are using can be charged in an efficient way.
3. Battery Charge Level Indicator: The current and voltage sensors are continuously monitoring the charging current and battery voltage respectively so that the charge level of the battery can be estimated accurately through a program written on codevision AVR. The SOC level can be monitored through LABVIEW.
4. Data Acquisition: The data acquisition of different parameters is done by the respective sensors (current, voltage and irradiance). Monitoring of these values will be done using LABVIEW. Whole day irradiance level can be easily plotted using wavegraph in LABVIEW.
