The objective of an AQAP is to ensure the quality of the components and reduce the uncertainty associated with the operation of a photovoltaic power plant, minimizing the risks of the investment and optimizing the economic return of the project.The uncertainty in the estimation of the energy that will produce a photovoltaic project influences its economic viability in two different phases. In the initial phase, determining the financing conditions through parameters such as EP90 or EP99. In the operation phase, limiting the ability to detect faults and, with it, to optimize the generation of energy. The realization of an AQAP allows to reduce the uncertainty and, with it, adjust the estimates and improve the return on the investment.
