  • Why a LCA of PV systems?

    o LCA : A tool to assist in decision-making that offers an overview of the environmental impacts of products or servic es.

    o Exponential growth of PV installations ���� need to provide reliable answers to questions such as:

    – What are the environmental performances of PV systems?

    ESPACE: Eco-conception of a photovoltaic system by its life cycle assessment and environmental impact European Workshop - Lyon, 30 October 2009

    – What are the environmental performances of PV systems?

    – Do investment incentives encourage good environmental choices?

    – What technologies of modules and what implementing techniques are the least penalizing?

    – What are the most sensitive parameters on the lifecycle of PV systems in terms of environmental impact?

  • Goals of the study

    o To bring scientific and technical arguments on the positioning of PV in terms of environmental impact.

    o To identify the main paths of improvement for

    ESPACE: Eco-conception of a photovoltaic system by its life cycle assessment and environmental impact European Workshop - Lyon, 30 October 2009

    o To identify the main paths of improvement for concerned industrials.

  • METHODOLOGY

    ESPACE: Eco-conception of a photovoltaic system by its life cycle assessment and environmental impact European Workshop - Lyon, 30 October 2009

    METHODOLOGY

  • Methodology

    o Task 1: Definition of objectives, review of bibliography and implementation of the LCA analysis

    ESPACE: Eco-conception of a photovoltaic system by its life cycle assessment and environmental impact European Workshop - Lyon, 30 October 2009

    – To identify the different components of a network-connected photovoltaic installation that will be the focus of the LCA.

    – To present the different manufacturing processes inherent to photovoltaic systems.

    13

  • Methodology

    o Task 2: Construction of a life cycle inventory

    – Inventory has been built based on data coming from industries and the EcoInvent database.

    ESPACE: Eco-conception of a photovoltaic system by its life cycle assessment and environmental impact European Workshop - Lyon, 30 October 2009 14

    – These data are related to the production, installation, maintenance and end of life of photovoltaic systems.

  • Methodology
