The ITE INES.2S is conducting research on life cycle analysis and is developing a tool for the analysis of the environmental impact of installations composed of photovoltaic (PV) panels and a battery storage system, in self-consumption. A guidance to make technological choices with regard to their environmental impacts.
Such systems combining renewable energies and batteries seem to be an interesting alternative to fossil fuels; however they also have their own environmental impacts. But technical and scientific literature often proposes very specific cases that do not allow to compare several scenarios easily nor to adapt the characteristics to the considered application. Moreover, the specific parameters of the different photovoltaic systems (efficiency, type of technology, location of the installation) and of the batteries (life span, energy density, ageing) can have a significant influence on the environmental results.
The tool developed by ITE INES.2S takes into account the different parameters of the installation and focuses on the different uses (countries of installation, modes of use, etc.) thus allowing a comparative analysis of the LCA in relation to a reference solution. It aims to help experts to optimize their models to ensure the environmental interest of a given storage solution.
