Assessment of advantages and limitations of installing PV on abandoned dumps

Abstract

The feedback of international practice shown that the installation of photovoltaic (PV) parc on the dumps is one of the best environmental and economic solutions. However, the number of projects is still very limited comparing to the identified potential. This paper addresses site selection criteria for landfill PV installation, particularly in relation to mining hazards. For installing the PV, different environmental, technical and economic criteria should be respected. The slope of the dumps appears as the main constraint for the installation of photovoltaic panels. In addition, specific foundation systems should be considered to ensure long-terms safety and security. The paper presents several examples of installation of photovoltaic panels on coal-lignite dumps in France.
