The Environmental Feasibility Study of Photovoltaic Systems Connected to the Network aims
to analyze possible environmental impacts of this technology production processes. The
justification is in the results obtained from this product Life Cycle Analysis, which showed
significant environmental impacts according to the six categories examined - Depletion of
Abiotic Resources, Climate Change, Depletion of the Ozone Layer, Human Toxicity,
Acidification and Eutrophication. Data were obtained with the help of Software OpenLCA
where the CML 2001 was chosen as a method of impact assessment and sustainability for a
photovoltaic system installed in Switzerland composed of a photovoltaic panel, an inverter and
a power 3kWp installation. The evaluation was made from the analysis of two models of panels,
one (monocrystalline and multicrystalline). Both technologies have proved to be feasible from
an environmental point of view. However, the choice of one or the other should be checked
from other viewpoints, for multicristalina technology despite having less environmental impact,
has lower efficiency compared to monocrystalline technology that even with higher efficiency
is more expensive and pollutes more.
