Design and Development of a Solar Based Portable Thermoelectric Heating Unit

The project titled “Design and Development of a Solar-Based Portable Thermoelectric Heating Unit” focuses on utilizing renewable solar energy to generate efficient and controlled heating through thermoelectric technology. Unlike conventional heating systems that rely on fossil fuels or resistive heating elements, this system employs thermoelectric modules operating on the Peltier effect, which can produce heat on one side when a DC voltage is applied. The system is powered by a 12V, 25W solar panel, making it self-sustainable, portable, and suitable for remote or off-grid applications. The generated heat is used for drying, warming liquids, or maintaining temperature-sensitive materials in medical or agricultural use. The design integrates heat sinks, temperature sensors, and control circuitry to maintain precise temperature levels while ensuring safety and energy efficiency. This eco-friendly heating solution reduces dependency on grid electricity, minimizes carbon emissions, and offers a reliable alternative for rural households, outdoor workers, and field researchers. The developed system demonstrates the feasibility of combining solar power with thermoelectric technology for sustainable and compact heating applications. Top of Form
