This study aimed to evaluate the techno-economic feasibility of producing solar panels using recycled plastic waste. The method involved analysing key economic indicators such as cumulative net present value, internal rate of return, break-even point, and return on investment, while incorporating science and technology concepts in materials processing and renewable energy systems. The results showed that although the CNPV was negative initially, the project started generating positive cash flow after the third year. This occurred because the recycling and solar integration processes provided long-term cost efficiency and sustainable value. By the twentieth year, profitability increased significantly, confirming the project's long-term viability. The integration of environmental engineering, polymer science, and photovoltaic technology contributed to the sustainable energy model. This solution offers an innovative pathway toward responsible consumption and production, aligned with Sustainable Development Goals. It also supports electricity needs in digital learning, especially in remote schools lacking stable energy access. © School of Engineering, Taylor’s University.
