This document outlines the design and assembly of a solar panel charge controller circuit. It describes the key steps taken which included: 1) Designing the circuit in Multisim software to test functionality and identify errors without building a physical prototype. 2) Assembling the circuit on a breadboard to test operation and get familiar with how the components work together. 3) Creating a printed circuit board (PCB) layout based on the schematic design to build the final product. 4) Connecting the solar panel, battery, and car park control system to power and charge the battery which will then provide electricity to operate the control system.

Introduction I am building a cost effective electricity source by using the sun or wind. It will charge a 12V acid battery which will be used to operated a car park control system. I will demonstrate how I achieved this, what skills I gained in the process and what I learned about building a circuit.
Block Diagram SOLAR PANEL 12V CONTROLLER TO RECHARGE BATTERY DC LOAD DC/AC INVERTER PLC 240 VOLTS CAR PARK CONTROL SYSTEM
Circuit Assembly I designed my circuit on the multisim, here I was able to see my mistakes and correct them without any damage or cost. Then I moved onto the bread board which allowed me to get a feel for how the circuit will actually work. Finally I assembled the final product on the PCB, allowing me to see my final product and what I had achieved.
Multisim Ø Computer programme where you build a circuit with the correct components. Ø Shows how the components work with each other. Ø How to connect the components. Ø It will be a functional schematic. Ø Helps when choosing the source for the circuit. Ø Can see the expected out put. Ø Shows any faults in the circuit.
Bread Board Ø After testing on multisim, I assembled my circuit on the bread board. Ø Pay attention to IC pin numbers when connecting to circuit. Ø Input and output of transistor pin is different on the schematic. Ø Capacitor polarities must be connected correctly. Ø LED connection must be round the right way. Ø
PCB Ø Red lines = copper. Ø Green lines = wire connection. Ø Connection based on schematic design.
Schematic Ø Deigned on the Express SCH. Ø Reference to the PCB connections. Ø
Circuit Connection to the Battery & Source Ø 12V Solar connected to circuit through diode, fuse and relay contactor. Ø Contactor works when batteries are full. Ø Extra charge will work 12V bulbs. No waste of electricity. Ø Batteries connected parallel. Ø Negative terminal connected to earth. Ø Output positive connected to battery positive.
Skills Gained Ø Learning about the multisim. Ø Understanding schematic diagrams. Ø PCB circuit design. Ø Soldering. Ø Component Testing. Ø Circuit Testing. Ø Logging everything in my note book. Ø Presenting the final design.
Conclusion This project was very enjoyable as it allowed me to learn new skills. It taught me how to use programmes that I will be using throughout my Engineering Career. It allowed me to keep track of what I was doing in order to achieve a final product.
