Renewable energy sources are essential to reduce the negative impacts on the environment caused by burning fossil fuels.
Using solar photovoltaic installations in recent years means that decision-makers must consider infrastructure renewal decisions.
An expenditure framework to achieve the optimal renovation period of photovoltaic modules is proposed here from an
economic standpoint. This approach includes not only the investment and maintenance costs but also energy and emissions
savings. A sensitivity analysis was carried out using a case study in south-eastern Spain, achieving that the optimal renovation
period ranges between 17.0 and 24.7 years. Many factors are studied to identify those with the greatest influence on this
indicator. Installing a solar power system is always a profitable choice considering that the installation lifetime is 25 years.
Neglecting the influence of these limits may cause potential savings not fully exploited.CRUE-CSICSpringer Natureresearch project "DESENREDA" through the 2021 call "Estancias de movilidad en el extranjero Jose Castillejo" of the Ministerio de Universidades CAS21/00085project "Hi-Edu Carbon" Erasmus Plus Programme, Key Action KA22021, action type 2021-1-SK01-KA220-HED-00002327
