“…At the present time, grid-connected PV power plants studies are interesting and informative, but based on the recent experimental studies, which are available in the literature [27][28][29] and to the authors' knowledge, there is still a lack of detailed performance analysis about mc-Si and p-Si PV module with almost similar electrical and mechanical characteristics. This paper aims to fill this gap by comparing the experimental behavior of these two common PV module technologies (mc-Si and p-Si) with exactly the same efficiency and maximum power at standard test conditions, the same mechanical properties, and almost similar in other electrical properties which experience the same fluctuations of solar irradiance and weather conditions.…”

“…It is extremely important to consider this factor in designing any PV system as it may cause a serious undersizing problem. According to [20][21][22][23][24][25], the average performance factor of PV systems in the selected testing field is about 67.2%. This result is further supported by this research, whereas the average performance factor of the tested module is found to be about 63.4%.…”

Abstract:In this paper, an efficient testing system for measuring a PV module's I-V curve is proposed. The proposed system is based on a controlled DC-DC boost converter. The advantage of using a DC-DC converter is that this converter is typically used in PV systems to track the maximum power point and to control the charging of the battery. Consequently, this device is utilized for I-V curve extraction without the need for further external devices. The I-V curve is extracted by modifying the duty cycle of the triggering signal of the boost converter's switch. The proposed system has been tested experimentally using a 120 Wp PV module. The results show that the proposed system can successfully extract I-V curves of PV module. Notably, the performance of the tested module, as measured by this study's system as well as with a reference system, was found to be in the range of 61-67% of the performance given in the datasheet. Hence, this result highlights the importance of considering a measurement of the actual performance of PV modules when designing any PV system so as to avoid an undersized system. The proposed I-V testing system can be used as a simple tool to diagnose any shortages or low performance problems in PV system.

“…It is worth to mention that the parameters and I-V characteristics of PV module are influenced by other meteorological and geographical factors, as well as to solar radiation and ambient temperature. 32,33 In previous studies, [23][24][25] the correlation of the input power of the motor-pump subsystem with the water flow rate and pumping head is derived directly from the experimental data of a specific system. These references do not analyze the performance of the optimal configuration of PVPS and do not specify the amount of excess water.…”

“…Furthermore, the PV module's parameters under STC are estimated on the basis of theoretical correlations, which represent the parameters of solar radiation and ambient temperature. It is worth to mention that the parameters and I‐V characteristics of PV module are influenced by other meteorological and geographical factors, as well as to solar radiation and ambient temperature . In previous studies, the correlation of the input power of the motor‐pump subsystem with the water flow rate and pumping head is derived directly from the experimental data of a specific system.…”

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.
