“…These systems are then characterized through a multidimensional criteria scenario to consider energy, economic, and environmental aspects. This characterization is in line with recent approaches addressed by the authors to discuss the application of renewables for underground water resource purposes [40]. From this preliminary characterization in a multidimensional framework, an MCDM approach is used to provide a classification of groundwater pumping systems, with the aim of making the identification of optimal solutions easier.…”

Herein, optimal groundwater pumping solutions based on a variety of energy resources and water storage options are estimated and classified. Each energy source and water storage option is first characterized considering energy, economic, and environmental criteria. A multi-criteria decision making (MCDM) process based on the analytic hierarchy process (AHP) and the technique for order performance by similarity to ideal solution (TOPSIS) is subsequently applied to identify and classify the optimal groundwater pumping solutions under such a multidimensional framework. An aquifer located in the southeast of Spain is analyzed in a case study to assess the proposed optimal MCDM-based approach. Conventional diesel-based equipment, solar PV power plants, and direct grid connection, as well as three water storage systems-direct pumping, seasonal storage, and annual storage-are identified as potential energy sources and water storage options, respectively. Characterization and visualization of these energy and water storage systems, as well as prioritized option results, are also discussed herein.

International policies mainly that are focused on energy-dependence reduction and climate change objectives have been widely proposed by most developed countries over the last years. These actions aim to promote the integration of renewables and the reduction of emissions in all sectors. Among the different sectors, agriculture emerges as a remarkable opportunity to integrate these proposals. Indeed, this sector accounts for 10% of the total greenhouse gas (GHG) emissions in the EU, representing 1.5% of gross domestic product (GDP) in 2016. Within the agriculture sector, current solutions for groundwater pumping purposes are mainly based on diesel technologies, leading to a remarkable fossil fuel dependence and emissions that must be reduced to fulfill both energy and environmental requirements. Relevant actions must be proposed that are focused on sustainable strategies and initiatives. Under this scenario, the integration of photovoltaic (PV) power plants into groundwater pumping installations has recently been considered as a suitable solution. However, this approach requires a more extended analysis, including different risks and impacts related to sustainability from the economic and energy points of view, and by considering other relevant aspects such as environmental consequences. In addition, PV solar power systems connected to the grid for groundwater pumping purposes provide a relevant opportunity to optimize the power supplied by these installations in terms of self-consumption and net-metering advantages. Actually, the excess PV power might be injected to the grid, with potential profits and benefits for the agriculture sector. Under this scenario, the present paper gives a multidimensional analysis of PV solar power systems connected to the grid for groundwater pumping solutions, including net-metering conditions and benefit estimations that are focused on a Spanish case study. Extensive results based on a real aquifer (Aquifer 23) located in Castilla La Mancha (Spain) are included and discussed in detail.

“…One of the most commons application of PV systems in the development countries is water pumping, which promotes social and economic development (KORDZADEH, 2010), mainly in isolated rural areas to cover human needs (RUBIO-ALIAGA et al, 2019). Such pumping application can be directed to irrigation in rural areas (SONTAKE; KALAMKAR, 2016), especially for family farmers not served by public services.…”

“…Such pumping application can be directed to irrigation in rural areas (SONTAKE; KALAMKAR, 2016), especially for family farmers not served by public services. Furthermore, irrigation is a major user of power and during recent decades has progressively required greater amounts of energy (RUBIO-ALIAGA et al, 2019). Besides costs reduction, innovations in renewable energy turns solar PV pumping irrigation a feasible technology to the progress (GAO et al, 2018).…”

Besides, water pumping is an important form of development in rural areas (family farmers) mainly because of the distance from distribution centers. Therefore, this paper aims to evaluate the energy conversion in a water pumping system applied to irrigation, powered by photovoltaic energy, and compare with a static system with a single axis manual three-steps sun tracking system. Two arrays of panels were installed in the field at 22° 42’30” S; 47°38’00” W; 546 m above sea level. One photovoltaic module was static and the other a manual sun tracking device. Each module was connected to an individual water pump to simulate an irrigation system. The results showed that the pumping system with manual tracking device had better performance in the energy conversion from photovoltaic to hydraulic, with increments of 177 MJ m-2, 50.87 more pumping hours, and 66,135 L. However, the conversion energy efficiency from solar energy to water pumping was 4.55% and 4.77% for tracking and static modules, respectively. The manual sun tracking systems used in the photovoltaic module feeding a pumping system to irrigation was a technical alternative to improve the performance of the photovoltaic system. Keywords: renewable energy, water pumped, pumping time, global efficiency. GRAH PONCIANO, V. F.; PONCIANO, I. M.; ALVES, D. G.; SARETTA, E.; COELHO, R.D. CONVERSÃO DA ENERGIA SOLAR FOTOVOLTAICA EM ENERGIA HIDRÁULICA APLICADA A SISTEMAS DE IRRIGAÇÃO UTILIZANDO UM RASTREADOR SOLAR MANUAL 2 RESUMO O Brasil tem um potencial solar energético pouco explorado, apenas 1,2% da matriz energética é proveniente da energia fotovoltaica. Aliado a isso, o bombeamento de água é uma importante forma de desenvolvimento nas áreas rurais (pequenos agricultores) principalmente, devido a distância desses locais aos centros de distribuição de energia elétrica. Este trabalho tem por objetivo avaliar a conversão da energia em um sistema de bombeamento de água aplicada a irrigação, movido por energia fotovoltaica, comparando um sistema estático com um sistema rastreador solar manual com três ângulos de ajuste de eixo único. Dois conjuntos de módulos foram instalados no campo na localização de 22° 42’30” S; 47°38’00” W; 546 m acima do nível do mar. Um módulo permaneceu estático e o outro módulo com um sistema de rastreador solar manual. Cada módulo foi conectado a uma motobomba individual, simulando um sistema de irrigação. Os resultados mostraram que o sistema de bombeamento com o rastreador manual teve melhor desempenho na conversão da energia solar para hidráulica, com um incremento de 177 MJ m-2, 50,87 h a mais no tempo de bombeamento, e 66.135 L. Contudo, a eficiência da conversão da energia solar para o sistema de bombeamento foi de 4,55% e 4,77% para o módulo rastreador e estático, respectivamente. O sistema manual de rastreamento solar utilizado no módulo fotovoltaico, alimentando um sistema de bombeamento para irrigação, foi uma alternativa técnica capaz de melhorar a desempenho do sistema fotovoltaico. Palavras-chave: energia renovável, água bombeada, tempo de bombeamento, eficiência global.
