Air conditioners are needed for areas that have a tropical climate like Indonesia. Conventional cooling systems use the utilization of a vapor compression refrigeration system where refrigerant is the working fluid. Refrigerant is a chemical used in the working cycle of a cooling machine that can damage the ozone layer if it decomposes in the air so that it can be a cause in global warming. The utilization of solar energy as an alternative energy source connected to thermoelectric can be a solution to produce cooling temperatures. This research aims to utilize renewable energy into an air conditioning system. This study uses a thermoelectric type TEC-12706 as a module for cooling a room measuring 300 mm x 300 mm x 300 mm and a solar panel with a capacity of 150Wp as an energy source. In the data collection that has been done for 8 hours from 08:00 to 16:00, the average temperature inside the room is 26 ℃ from the average temperature outside the room of 30 ℃. After calculating the Coefficient of Performance (COP) value of the cooling system from the data that has been taken, the COP value of the cooling system from this study is 0.167944.
