The objective of this paper is to present an accurate overview of the LCA already performed on PVs. The analyses are classified by panel type and by impact assessment methodology. When available the information relative to the PV system (efficiency, localization, etc.) is also summarized.
The life cycle assessment and techno-economic analysis was implemented from the viewpoints of life cycle carbon footprint, production cost, raw materials cost, solar energy cost, and carbon tax. The main research conclusions were simply characterized as follows:
Solar energy is radiation from the Sun that is capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world''s energy requirements and could satisfy all future energy needs if suitably harnessed.
Existing PV LCAs are often based on outdated life cycle inventory (LCI) data. The two prominently used LCI sources are the Ecoinvent PV datasets [22], which reflect crystalline silicon PV module production in 2005, and the IEA PVPS 2015 datasets [3], which reflect crystalline silicon PV module production in 2011.Given the rapid reductions in energy …
