Solarcell mobile water pump4/7/2023 ![]() ![]() The estimated capacity of PV solar energy installed is 2.250 kWp. In Mozambican’s context, PVWPS for irrigation have been expanding slowly but have gained expression since 2013 with significant development. deepen the historical context and refer that these types of systems have been used in massive scale since 1977 in many countries of the world, mainly in developing countries of Africa, Asia and South America. However, the evaluating of availability of solar and water resources before installing any PV system for irrigation is necessary in order to guarantee optimal solutions.įedrizzi mentions different PV systems for water pumping developed around the world, and although some PV systems projects need some care and improvement, the number of systems already installed shows that the technology is technically mature (see Section 2.1). The use of solar photovoltaic (PV) energy technology for water pumping systems (WPS) for irrigation has been one of the most popular forms of solar energy application, in recent decades, in remote and desert areas, as well as in some urban areas. Thus, the direct relationship between the availability of renewable resources and water demand for irrigation urges researchers and local stakeholders to analyze the feasibility of WPS. ![]() New conversion methods are explored in order to minimize dependence on fossil fuels. Since agriculture is a vital activity for the maintenance of humanity, the adoption of self-sustaining agricultural production practices using renewable and endogenous energy resources becomes an essential element for the development of communities, either economically and socially. However, the irrigation process in modern agriculture is still based on the exploitation of fossil fuels. Įconomists cited by Vann Koppen, Namara and Safilios-Rothschild argue that agriculture is the engine of all economic growth, as a consequence, reduction of poverty throughout history. In Mozambican’s case, more than 70% of the population does not have access to the conventional electricity network. In addition, they are also a key tool for developing countries, where a significant part of the population does not have access to the conventional electricity network. In a world struggling with climate change and global warming, renewable sources of electricity generation are a very important response to climate issues. The adoption of PVWPS is a means of increasing the sustainability of the rural communities. In Mozambique, PVWPS match the perspective of different researchers regarding the availability of solar resource, boreholes and amount of water required for irrigation. In turn, static models based on software of pump manufacturers for PVWPS design are the most widely used in Mozam-bique. For the Mozambican’s context, PVWPS for irrigation has been expanding slowly but has gained expression since 2013. ![]() Yet, as research gap, it is possible to understand from different authors that the dynamic nature of the end-use of PVWPS is not explored on methodology design of PVWPS, and the techno-economic optimum system configuration is not always the one that gives the highest annual system efficiency. Looking at the designing, mathematical models, software-assisted is being predominant. Yet, the efficiency of the PV and overall system does not exceed 10% and 5%, respectively. The mainly variables that influence the performance of PVWPS are: total dynamic head, quantity of fluid extracted, variation of solar radiation level, PV and motor pump technology. These systems are simple and reliable, mainly used in small-scale pumping for small irrigations and domestic use. The results show that the most commonly used configuration of PVWPS technology is direct coupling systems without battery storage. Additionally, this paper intends to analyze the Mozambique’s perspective on renewable energy technologies setting the Mozambican scenario regarding photovoltaic water pumping systems (PVWPS) technology with the aim to identifying the main knowledge of PVWPS design and research gap. In this article, an advanced literature review on the design and performance of solar technology for water pumping is presented, exploring also the best perspective of transition for the developing countries energy needs. The use of solar photovoltaic (PV) technology for water pumping systems (WPS) has been one of the most popular forms of solar energy application in recent decades in remote and desert areas, as well as in some urban areas. ![]()
