Background: Fossil energy is an energy source that comes from nature and contains hydrocarbons such as gas, coal, and oil. Many other forms of renewable energy are available in Indonesia, such as solar, wind, and hydroelectric energy. We know that Indonesia is located on the equator. So it has a very abundant source of solar energy. However, in Indonesia, solar energy has not been utilized optimally. Even though solar energy has a source of heat energy that can be used as electrical energy using solar panels. The purpose of this study was to determine the effect of the effectiveness of using monocrystalline type 150-watt solar panels on AC and DC lamps on the electricity generated and to make learning media from the results of this research. This research was carried out at the Physics Education Laboratory on January 25–31, 2019 and at the East Lampung MAN 1 school on March 8, 2019. Method: The data collection method uses the experimental method. The research design was carried out to determine the effectiveness of using monocrystalline-type 150-watt solar panels on AC and DC lamps. Result: Based on the results of the research that has been done, it can be seen that the value of the effectiveness of using monocrystalline type 150-watt solar panels on AC lamps is 26.62%. While the value of the effectiveness of using a 150-watt solar panel-type monocrystalline DC lamp is 73.58%. In addition, the product of this research is in the form of media posters, which are used as learning media. Keywords: Fossil Energy, Renewable Energy, Solar Panels, Effectiveness of AC and DC Lamps, Media Posters.
