A method to estimate optimal renovation period of solar photovoltaic modules Pardo, Miguel Ángel Jódar Abellán, Antonio Rodrigo Comino, Jesús Renovation strategy Large-scale photovoltaics Economic feasibility Potential energy savings Regional approaches 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. 2022-09-28T11:44:46Z 2022-09-28T11:44:46Z 2022-08-30 journal article Pardo, M.Á... [et al.].
