Abstract Lower operating temperatures of the photovoltaic (PV) cells increase the performance and efficiency of any PV installation. The efficiency of solar photovoltaic water pumping system (SPVWPS) decreases considerably with the increase in the PV cell temperature. In this paper, the performance of a 2 hp SPVWPS has been investigated experimentally, for the influence of panel cooling, using water. The experimental observations have been made under climatic conditions of Visvesvaraya National Institute of Technology, Nagpur campus, India, during the year 2018. The performance was evaluated under four different cases: (a) without panel cooling, (b) with water cooling on the top of the panel surface, (c) with water cooling on beneath the surface of the panel, and (d) with water cooling beneath the surface of the panel using jute. The effect of different cooling cases on the various performance parameters such as discharge, power output, pump efficiency, and system efficiency has been analyzed and discussed. The results showed that the water cooling on the top of the panel and beneath the surface of the panel with jute has considerable influence on performance enhancement when compared with other cases.

And Performance

Photovoltaic technology is an effective, reliable and rapidly developing technology to convert solar energy into electrical energy. In the recent years, the need and demand of solar photovoltaic water pumping system has been increased as a stand-alone water pumping system to pump water in remote, desolate and mountainous region for end use of livestock watering and rural/urban water supply system. For a required pumping head, photovoltaic array configuration and its size (peak power rating, Wp) affect the flow rate of pumped water, economy and performance of solar photovoltaic water pumping system. The recent work is aimed to study performance of a directly coupled solar photovoltaic water pumping system at different pumping heads (2 bar, 3 bar, 4 bar, and 5 bar) and different photovoltaic array configurations (3S?2P, 4S?2P, 5S?2P, 6S, 7S, and 8S) for the real meteorological conditions of the Vidarbha region, central India (Nagpur). A comparative study has been done to investigate the head effect on the optimum photovoltaic array configuration, pump and pumping system total efficiency by performing experiment on the centrifugal deep well pump (SQF 5A-7), with 6-10 photovoltaic modules (200 W each) with various configurations and different heads. It is concluded that the 4S?2P and 5S?2P configurations are most optimized array to provide optimum energy at all pumping heads.

Perturb And Observe

<p>Solar photovoltaic systems convert energy of light directly into electrical<br />energy. This work presents, a process to compute the required size of the<br />stand-alone solar photovoltaic generator based water pumping system<br />for an existing area. In addition solar photovoltaic generator is<br />connecting voltage source inverter fed vector controlled induction<br />motor-pump system. Perturb and observe are used for harvesting<br />maximum power of PV generator in between buck-boost DC converter<br />and inverter system. In this paper system result is validated by fuzzy<br />logic system and compare with variable frequency drives based PI<br />controllers, driving motor-pump system. The operational performance<br />at 60 m head, VFD based controllers in terms overshoot and setting time<br />and also analysis performance of motor-pump set under different<br />weather conditions. By assessment of system we find that speed and<br />torque variation, overshoot and settling time is more with PI controller,<br />Fuzzy logic controller (FLC) performance have dominance to VFD<br />based PI controller.</p>

The Impact

This paper investigates the impact of tube wells on the discharge and water table of the Quetta Valley aquifer and conducts a financial analysis of the solar photovoltaic water pumping system (SPVWP) in comparison with a typical pumping system for the Water and Sanitation Agency of Quetta’s (WASA) tube wells. Quetta Valley is dependent on groundwater as surface resources are on decline and unpredictable. The population of this city has exponentially increased from 0.26 million in 1975 to 2.2 million in 2017 which has put a lot of pressure on the groundwater aquifer by installing more than 500 large capacity tube wells by WASA and Public Health Engineering (PHE) departments in addition to thousands of low-capacity private tube wells. The unprecedented running of these wells has resulted in drying of the historical Karez system, agricultural activities, and the sharp increase in power tariffs. There are 423 tube wells in operation installed by WASA in addition to PHE, Irrigation and Military Engineering Services (MES), which covers 60% of the city’s water demand. The results will be beneficial for organizations and positively impact the operation of these wells to meet public water demand. For the two zones, i.e., Zarghoon and Chiltan in Quetta Valley, recommendations are given for improved water management.
