This illustration explains how the Feston Solar Air Conditioning System works to deliver energy-efficient and eco-friendly cooling. Solar panels installed outside the building capture sunlight and convert it into electrical energy. This clean solar energy is then supplied to the Feston outdoor AC unit, which powers the compressor and fan to begin the cooling process.

The outdoor unit transfers the cooling through the system to the Feston indoor air conditioner, which is mounted inside the room. The indoor unit distributes cool air evenly across the space, creating a comfortable indoor environment.

During the daytime, the Feston Solar AC system primarily operates using solar power generated from the panels, helping reduce electricity consumption and lowering energy costs. The system is also connected to a standard AC power source as a backup. When solar energy is not sufficient, such as at night or during cloudy weather, the system automatically switches to grid electricity to ensure uninterrupted cooling.
