<![CDATA[Electricity is essential for everyday needs, including food preservation through refrigeration. However, access to electricity remains uneven in remote regions due to geographical constraints. Solar energy offers a promising alternative, especially in areas with abundant sunlight, highlighting the need for compact, portable, and eco-friendly cooling system. This study aims to design an eco-friendly cooling system using the Seebeck Effect in Peltier TEC 12706 modules powered by solar energy. The system consists of two Peltier TEC 12706 modules, a 50 Wp solar panel, and a 33 Ah accumulator, with a cooling chamber measuring 26 × 17 × 10 cm. Temperature and humidity were remotely monitored via the Blynk application. Experimental results showed the lowest temperature achieved was 15°C between 08:00 AM and 10:00 AM. In comparison, the most significant temperature drop of 11.7°C occurred between 12:00 PM and 02:00 PM, with an average light intensity of 176,846.15 Lux. Although the system demonstrated cooling performance, the minimum temperature of 15°C does not meet the standard refrigeration temperature of around 0°C. Therefore, the current system is not yet suitable for replacing conventional refrigerators, but it shows potential as an environmentally friendly alternative cooling solution with further development.]]>
