Abstract

KASIM, N. K.; HUSSAIN, H. H.  and  ABED, A. N.. Boosting the energy output of an On-Grid solar PV system using a novel techniques. J. appl. res. technol [online]. 2023, vol.21, n.6, pp.1066-1074.  Epub Aug 13, 2024. ISSN 2448-6736.  https://doi.org/10.22201/icat.24486736e.2023.21.6.2036.

Two techniques have been used in this study to boost energy output of an on-grid PV system. Boosting energy output is achieved by improving the solar PV system performance parameters. Planar concentrators and cooling are two techniques used to boost energy output. The current solar PV system is placed in Baghdad/Al-Mansour corporation. This work includes improving the following performance parameters: performance ratio (PR), array efficiency, array yield, electrical energy, as well as solar irradiation. All these improvements are accomplished by increasing solar irradiance using planar concentrators (made of aluminum metal) and cooling (via water). The monthly daily average energy produced of enhanced and reference PV modules is 14.2 kWh and 11.1 kWh, respectively. The monthly daily average array yield of the enhanced PV modules and reference PV modules is 7.14 kWh/kWp and 5.61 kWh/kWp, respectively. The monthly daily average solar irradiation of the enhanced and reference PV modules is 7.71kWh/m2 and 6.101kWh/m2, respectively. The monthly daily average efficiency and performance ratio of the enhanced and reference PV modules are 14.3% & 93.6%, and 13.9% & 91.1%, respectively. The maximum average monthly temperatures of the enhanced and reference PV modules are 48.5°C and 57.4°C, respectively, in July, where the ambient air temperature is 42.1°C. The successful optimization of the performance (PR) parameters of an on-grid PV system is the novel aspect of this work. In addition to developing a novel system to increase the performance of second-generation solar PV modules (CIGS).
