Abstract

Photovoltaic solar system is the technology that converts energy from sunlight into electrical energy. Generally, it consist several components including solar panel to absorb and convert the irradiance from sun light into electricity. The availability of the irradiance also depends on the weather condition that brings much variation and uncertainty. The irradiance at top of atmosphere was 1,367 W/m2 and the radiation can easily absorbed, reflected and deflected by the cloud type. In other word, the solar irradiation will decrease because of the blocking and movement of the cloud. From that,this project had to emulate the cloud movement by replacing the cloud with tinted film. The percentage of the tinted film which is 50%, 65%, 80% and 95% to emulate the cloud that brings different effect on output PV module. The different output can be seen on the measurement of the solar such as voltage and current. Furthermore, to emulate the cloud, the panel had to create to hold the tinted film and make the panel moving slowly. The moving panel had to move with suitable gear so that it can emulate the cloud moving.From that, the required parameter can be taken with suitable equipment.
