“…More recently, Belgacem (2012) studied the performance of solar photovoltaic operated submersible water pumping system. Campana et al (2013) proposed a dynamic modeling tool for the design of a of photovoltaic water pumping system by combining the models of the water demand, the solar PV power and the pumping system, which can be used to validate the design procedure in terms of matching between water demand and water supply.…”

Optimum configuration of solar photovoltaic (PV) power generation system has been carried out for achieving a minimum cost of energy (COE) in five different geographic locations in Saudi Arabia, namely, Dhahran, Riyadh, Jeddah, Guriat and Nejran . The ultimate goal in the present study is to investigate and compare the performance of both the diesel and solar PV stand-alone power generating systems for underground water pumping purposes. It is found that the solar PV power generating system not only helps to decrease carbon emission to the atmosphere but also is comparable in the unit COE with the diesel only system in many sites even though the unit price of the diesel fuel is very low.The proposed diesel only system produces annually about 24,069tons of green house gases which can be otherwise eliminated by using solar PV system. Cost of water pumping from an underground well of 50m total dynamic head is found to vary from 10 -17US¢/m 3 for the five Downloaded by [Istanbul Universitesi Kutuphane ve Dok] at 23:11 04 November 2014 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT2 sites considered. When compared with the diesel only system this range of cost is found to be comparable when the diesel fuel price is 0.6$/L or more.

“…In Reference [18], it is indicated that most farmers in Latin American countries have old and inefficient irrigation systems, resulting in an overconsumption of energy, which accounts for approximately 50% of the annual operational cost. Similar situations are observed around the world: Reference [19] reported pump efficiencies ranging between 20% and 30% in existing irrigation systems in Tunisia; Reference [20] reported a motor-pump performance of 30%. An inefficient irrigation system requires an unnecessarily oversized solar PV system.…”

Abstract:In the last five years, the Chilean Ministries of Agriculture and Energy developed a national strategy to incorporate renewable energies into various economic sectors. Since 2013, more than 1500 off-grid solar photovoltaic (PV) systems, with power ranging from 1 kW to 3 kW, were installed to drive existing irrigation systems in small and medium-sized farms for the exportation of fresh fruit. A net billing regulation was also implemented in 2014. This study shows a cost-effective methodology for the sizing of solar PV systems for existing irrigation facilities in Chile, in an effort to improve the competitiveness of the fresh-fruit industry. The same methodology may also be implemented in other Latin American countries. The article presents the analysis of four projects (two in the Atacama Region, and two in the Maule Region). The baseline situation of the four units was studied, as well as the energy-efficient actions that may be applied, in addition to the recommended characteristics of the selected PV system to drive the irrigation systems of small fresh-fruit farms. Off-grid and on-grid solar PV systems were analyzed, including some particularities of the Chilean regulations. The required water demand of the irrigation systems and their corresponding pressure heads were also determined. The electricity demand of the system was calculated, and the PV system was designed for an optimal irrigation system. Additionally, an economical assessment was made for two years. In the first year, the cost effectiveness of energy-efficient actions was evaluated for the irrigation system, and it was found that they had paybacks of approximately two years. In the second year, the implementation of a PV system in each demonstrative unit was evaluated. The on-grid solar PV system performed better than the off-grid system, with evaluated paybacks of approximately 12 years. Finally, some recommendations for a well-designed on-grid solar PV system were made on the basis of it lasting over 25 years, with an adequate operation and maintenance plan.

“…3 Many studies have focused on the performance of PVPS. [4][5][6][7][8][9][10] Such studies lead to the conclusion that PVPSs are more feasible than diesel-generated systems. They also indicate that the average daily water flow rate is in the range of 5.333 to 26.022 m 3 /kWp and that the overall efficieny of the system is in the range of 1.299% to 5%.…”

Summary Solar energy is effectively used to power stand‐alone photovoltaic pumping systems (PVPSs) for irrigation and drinking purposes in remote areas. However, random vicissitudes and the unpredictability of the amount of solar energy that can be harnessed lead to difficulties in designing PVPS. Thus, an optimal sizing approach is essential to ensure satisfactory performance. In this paper, a numerical iterative sizing approach based on technical and economic objectives is developed to optimize the configuraion of PVPS. The loss of load probability criteria is considered as the technical objective, while the life cycle cost criteria is considered as the economic objective. The proposed pumping system provides a daily water for a small village in Kuala Lumpur, Malaysia. The proposed sizing approach is used to test all the possible configurations of a wide range of photovoltaic (PV) array sizes to specify the PV array configurations that realize the reliability condition. The optimal size of the storage tank and the optimal number of PV modules connected in series and parallel are specified to keep up a balance between the loss of load probability, life cycle cost, and excess water volume of PVPS. The performance of the system is tested on the basis of the proposed optimal configuration and hourly meteorological data for 1 year. The results show that the proposed system is available throughout most of the year.
