Abstract

Solar energy is an energy that comprises both characteristics of green energy and renewable energy as it does not give out harmful emission and the sunlight from the Sun is limitless, abundant and infinite. The solar panel with phyllotaxis pattern is introduced in order to solve the portable, weight and space issues. A phyllotaxis pattern solar panel is a solar panel that can be opened in the form of blooming flower. This project was carried out in order to design phyllotaxis solar panel, fabricate the prototype of phyllotaxis solar panel and optimize the output of phyllotaxis pattern of solar panel. A final concept of phyllotaxis solar panel was chosen by using concept scoring method. The parts of the phyllotaxis pattern solar pattern which were produced by using rapid prototyping process with Nylon PA66 were stepper motor housing, honeycomb stand bar, link bar, blades and base. A stepper motor was used in opening and closing the solar panels while the erection mechanism was controlled by a linear actuator. According to the analysis result, the Von Mises stress of the honeycomb pattern stand bar and link bar were less than tensile strength of assigned material Nylon 66 which is 63.6MPa hence the design and material of the critical parts are passed for further fabrication process. The voltage output of 2 series connected solar cells doubles the voltage output of a single solar cell. The result collected for parallel connected solar cells is close to the statement that the current is the same for every component connected in series. A single solar cell has a maximum output voltage of 5.5V and maximum current of 90mA while a pair of series connected solar cell has maximum voltage output of 11V and maximum current of 40mA. In order to optimize the output voltage output of solar panel to charge a 12V battery, the solar cells are arranged in parallel into 4 rows with each row consist of 4 solar cells. In conclusion, the objectives of the project were achieved by designing, fabricating and optimizing a phyllotaxis pattern solar panel.
