In the recent years, technologies have become more advanced and the world has been developing which led to an increase in demand in energy. To sustain energy demand, alternative methods must be proposed. In Singapore, solar energy can be the main source of energy as sunlight is present throughout the year. The term of harvesting solar energy simply means the sun’s ray will be converted into other form of potential energy such as heat and electricity. The most common ways to harvest solar energy is by utilising solar panels due to its sustainability, cleanliness, and ubiquity. However, due to Singapore small physical size, high population density and land scarcity, it is unable to deploy solar panels on a large scare to generate electricity. One way to overcome this limitation will be installed on the window railing of individual household. To ensure maximum efficiency, integration of solar tracker to the system will ensures that the solar panels will always be aligned to the sun’s position which will further leads to an increase in overall light intensity. The harvested solar energy will be converted into electrical energy then be stored in battery during day time and be utilised during night time. The battery will be connected to a DC/AC converter to power up low AC appliances. Finally, a charge controller will also be integrated into the system. The objective of the charge controller is to control the charging process of battery, such as preventing overcharging, which will cause damages to battery. In this report, it will discuss on the implementation and testing of integration of dual axis solar tracker and pulse width modulation charge controller. All the systems will be controlled and operated by Arduino Uno.
