Enhancing Sustainability of Solar Irrigation Pumping Systems: A Technical and Economic Evaluation of Single and Multi-Crystalline Silicon Solar Panels Using System Advisory Model

Abstract

This article presents a techno-economic analysis of single and multi-crystalline silicon solar panel installations for solar irrigation pumping applications in two cities in South Punjab, Pakistan. The study considers various economic parameters, such as net capital cost (NCC), levelized cost of electricity (LCOE), net present value (NPV), and payback period by employing system advisory model (SAM) software. The results indicate that although monocrystalline solar panels have a higher initial cost than polycrystalline panels, they offer higher efficiency, longer lifespan, and lower maintenance costs, resulting in a lower LCOE, higher NPV, and shorter payback period. This study also examines the material science aspect of silicon used in Mono (Single) and Poly (Multi) crystalline solar panels. The impurity and purity levels of silicon in the panels can greatly affect their performance and durability. Monocrystalline panels are made from a single, pure crystal of silicon, while polycrystalline panels are composed of multiple crystals. The study also provides insights into the impurity and purity levels of silicon and their impact on the performance of solar panels. The findings of this study can help decision-makers in choosing the optimal solar panel technology for their energy needs in the region.
