Life Cycle Inventories of photovoltaics
Several activities are ongoing to update the life cycle inventories of photovoltaics. The full project is lead by ESU-services.
Solar radiation is a source for renewable energy. One possible use is the production of electricity in photovoltaic appliances (PV). The aim of this report is to provide up-to-date data for the environmental impacts of electricity production with photovoltaic appliances in Switzerland and Europe. The data for photovoltaics have been updated with financial contribution of the European Photovoltaics Industry Association and the Swiss Federal Authority for Energy.
Data have been collected in this project directly from manufacturers and were provided by other research projects. Life cycle assessment (LCA) studies from different authors are considered for the assessment. The information is used to elaborate a life cycle inventory from cradle to grave for the PV-electricity production in 3kWp plants in the year 2005. The inventory is investigated for single- and multicrystalline cells, ribbon-silicon, amorphous-silicon, CdTe and CIS thin film cells. Environmental impacts i.e. due to the infrastructure for all production stages are also considered in the inventory.
The data are published together with ecoinvent data v2.1. The latest update of photovoltaic data (v2.2+) can be downloaded here.
The project is financed by the following institutions:
- Swiss Federal Office of Energy (Bundesamt für Energie), BfE, CH, Program Photovoltaik
- European Photovoltaic Industry Association (EPIA) , BE
