An overview on performance of PV plants commissioned at different places in the world

Solar PV technology is the most promising renewable energy technology and is able to fulfill the electricity demand of the whole world even after conventional sources are completely finished. The prediction of actual electricity output from PV plants under actual outdoor conditions is tough. Performance evaluation of installed PV plants is helpful in designing and prediction of the performance of other upcoming PV plants more precisely. IEC 61724 gives the standards by which the performance of a PV plant can be judged. At present, several research works based on performance evaluation of PV plants carried out in distinct locations across the world are reported in the literature. It is important to review results from various case studies on the basis of the IEC 61724 standard. In this paper, the various case is reviewed on the basis of their location, commissioning year, capacity, used technology, and their performance. This will be helpful to design a PV plant knowing previous commissioned plant performance. From the review, it has been found that PV plants are installed in most of the countries in the world and they are demonstrating satisfactory results. It has also been found that PV module material and panel tilt angle is very crucial for designing a PV Plant. (C) 2019 International Energy Initiative. Published by Elsevier Inc. All rights reserved.
