Abstract:
This paper presents a comprehensive evaluation of Life Cycle Engineering (LCE) processes for enhancing the sustainability of solar electricity gadgets, addressing the crucial need for holistic environmental assessment in renewable energy technology. While sun power systems offer sizable environmental advantages at some point of operation, their manufacturing, installation, and quit-of-life phases gift extensive sustainability challenges that require systematic evaluation. This review synthesizes modern-day literature on LCE applications in photovoltaic and solar thermal structures, inspecting eco-layout principles, modularity strategies, additive production improvements, and round economy procedures. Key findings display that electricity payback instances for crystalline silicon PV systems have reduced to one-four years, at the same time as carbon footprints range from 20-50g CO2-eq/kWh, considerably decrease than fossil fuel alternatives. However, essential know-how gaps persist in recycling technology, fabric healing economics, and standardized assessment methodologies. The paper identifies 4 primary studies opportunities: improvement of design-for-disassembly protocols, advancement of selective fabric recovery strategies, integration of digital twin technologies for lifecycle optimization, and established order of circular business models. These findings offer a roadmap for researchers and practitioners attempting to find to decorate the sustainability of solar power structures thru complete lifecycle processes, in the end supporting the transition to a spherical economic system in renewable strength sectors.
