Solar Powered Air Conditioner

Abstract: This project presents the design and implementation of a solar-powered air conditioning system using thermoelectric Peltier technology. The system is built around a 12V 20W solar panel that charges a 12V 12Ah lead-acid battery through a PWM-based solar charge controller. The stored power is used to run a cooling unit consisting of three TEC1-12706 Peltier modules housed inside a metal box. These modules create a temperature difference, producing a cold side for cooling and a hot side for heat dissipation. Air blower is used inside the box to circulate air across the cold surface, enhancing the cooling effect
