Abstract

Nowadays, the usage of electrical energy are uncontrolable due to the electrical appliance used whether at home or others. Instead of water, charchoel and nuclear, solar energy can be used to generate electricity. With solar energy, it could generate energy without pollution. In this projek, solar energy is used as a main supply. From solar panel, it would charged the battery during sun hour to be used at night. From the research, solar panel can generate up to 4V when it is not exposed to the light and could achieve up to 8V when it is exposed to light of lamp. By exposed it to full of sunlight, it can achieve more than 12V. For this project, shunt regulator was used to prevent the solar panel from overcharging the battery. Since the solar panel are very sensitive to the shading, it set to move from east to west to generate maximum energy as it can. As a backup system, sensor circuit is created to sense the light during rainy or cloudy day. To implement this project, it needs high cost but for long term usage, it is saving.
