Dual-Mode Pv Systems for Water Harvesting

This monograph presents the design and analysis of a dual mode photovoltaic system that combines daytime solar electricity generation with nighttime radiative cooling for atmospheric water harvesting. The study focuses on the use of a high emissivity cooling surface to reduce surface temperature at night and promote moisture condensation from the surrounding air. The work discusses the construction principles, material selection, expected water collection performance, integration with solar panel cleaning, and sustainability potential in dry and semi dry regions. Special attention is given to low cost design, practical implementation, energy efficiency, and environmental benefits. The monograph can be useful for researchers, engineers, students, and innovators working in renewable energy, solar technologies, water harvesting, and sustainable engineering solutions.
