Presentation of the Photovoltaic energy production emphasizing at reduced efficiency of Photovoltaic energy output in Photovoltaic system. An analysis of failure events and explanation of losses with on site and in laboratory data collection methodology combined studies on a global scale and measurements of photovoltaic systems installed in Greece as well. In addition a composition of Fault Tree Analysis took place in reference of failure events. An optimization of the events presented in that thesis .This optimization includes incidence rates , the gravitation influence of facts in the whole system and the cost required to eliminate or may not reappear , if that becomes technically feasible. Remidial proposals to major incidents of failure are also suggested. Finally,(out of the initial frame of this thesis but occur as a relevant follow-up part) multicriteria analysis regarding on quality of photovoltaic module related to the benefit of each module technology is presented.
