Modeling LCA (Life Cycle Assessment) for solar photovoltaic systems in Simapro is a key step in assessing their environmental impact throughout the entire life cycle, from production and use to end-of-life and recycling. Simapro is one of the most well-known software tools for conducting life cycle assessments and enables detailed analysis of environmental impacts based on data on emissions, resource consumption, and other parameters. The first step in modeling LCA is gathering accurate data on all phases of the photovoltaic system’s life cycle, including panel production, transport, installation, use, maintenance, and recycling. It is also important to select the appropriate methodology, such as CML, TRACI, Eco-indicator 99, or ReCiPe, depending on the specific goals of the study. This tool enables precise assessment of environmental impacts through analysis of CO2 emissions, resource consumption, and the energy required for the production and transport of materials such as silicon, glass, and metal frames. Additionally, assessing the end-of-life phase and the potential for recycling panels can significantly impact the overall ecological footprint. Using Simapro allows users to visualize and interpret data through graphical and tabular displays, which facilitates comparison of different scenarios and identification of areas for improvement in terms of sustainability. Such analyses are crucial for making informed decisions in the solar technology industry and for promoting sustainable solutions in energy production.
