The increasing demand for sustainable energy solutions has driven the development of innovative methods for harnessing renewable energy. This paper presents the design, construction, and implementation of a cost-effective solar air collector made from recycled aluminum cans. By utilizing readily available, low-cost materials, this system offers an accessible and eco-friendly approach to improving energy efficiency. Its construction requires only basic tools and skills, making it feasible for individuals, households, and small communities to build and install their own solar collectors. This approach not only reduces waste by repurposing aluminum cans but also helps lower heating costs, particularly in colder climates. The system effectively raises air temperature, providing a practical solution for supplemental space heating. The primary goal of this paper is to demonstrate the potential of Do-it-yourself (DIY) solar collectors as an affordable, scalable technology for enhancing energy efficiency while promoting environmental sustainability.
