Building Integrated Photovoltaic Thermal (BIPVT) systems offer several benefits, but the materials involved, such as photovoltaic cells and various materials/components, significantly affect their environmental impact. Therefore, assessing the environmental profile of BIPVT systems through Life Cycle Assessment (LCA) is essential. This study conducts an LCA to evaluate the environmental performance of a specific BIPVT configuration designed for the climate in Srinagar, India. It focuses on material manufacturing impacts using indicators like Global Warming Potential (GWP), ILCD, Impact 2002+, Ecological Footprint, and USEtox. The findings indicate that PV cells, steel support structures, and rubber gaskets of the system components has maximum environmental impacts across all assessed indicators. Additionally, based on USEtox indicators for ecotoxicity and human non-cancer toxicity (considering primary materials), PV cells were found to contribute the most to the module’s total impact: 64% for ecotoxicity and 68% for human non-cancer toxicity.

摘要

Building Integrated Photovoltaic Thermal (BIPVT) systems offer several benefits, but the materials involved, such as photovoltaic cells and various materials/components, significantly affect their environmental impact. Therefore, assessing the environmental profile of BIPVT systems through Life Cycle Assessment (LCA) is essential. This study conducts an LCA to evaluate the environmental performance of a specific BIPVT configuration designed for the climate in Srinagar, India. It focuses on material manufacturing impacts using indicators like Global Warming Potential (GWP), ILCD, Impact 2002+, Ecological Footprint, and USEtox. The findings indicate that PV cells, steel support structures, and rubber gaskets of the system components has maximum environmental impacts across all assessed indicators.
