Influence of Operation and Maintenance expenditures in the feasibility of photovoltaic projects: The case of a tracking pv plant in Spain

Operation and Maintenance (O&M) tasks are becoming increasingly important in the asset management of photovoltaic projects. However, there is insufficient evidence to analyse in depth its influence on the energy and economic performance of such systems. The wide range of O&M annual expenditures (OPEX) and the lack of standardization further complicate the proliferation of specialized studies. This paper analyses the influence of OPEX on the...
