Abstract

Four grid-connected solar Photovoltaic (PV) systems were installed at Universiti Teknikal Malaysia Melaka (UTeM), namely Thin-Film (TF), Heterojunction with intrinsic thin layer (HIT), Poly crystalline, and Mono crystalline with the total capacity of 24 kWp since October 2013. Hence, it is important to evaluate the performance and the degradation of UTeM’s PV systems. In this regard, this research aims to evaluate the performance and the degradation of three of the four grid- connected PV systems located at UTeM, Melaka. The analysis presented in this study consists of the data recorded at 5 – minute intervals between January 2014 and December 2015. Meteorological parameters such as solar radiation and ambient temperature, module temperature, and solar generation were obtained from research laboratory of solar PV systems, smart grids, UTeM. The annual performance of the PV systems had been evaluated in terms of capacity factor, availability factor, reference yield, array yield, final yield, performance ratio, system losses, and array capture losses. The annual degradation rates of the PV systems were calculated using Power-Irradiance (P-G) technique. The average performance ratio of Thin-Film PV system for 2014 was 93.6% and 89.2% in 2015, while the average performance ratio of HIT PV system in 2014 was 85% and 82.3% in 2015, and the average performance ratio of Mono crystalline PV system in 2014 was 81.3% and 78.7% in 2015. The average degradation rates for two years of operation of Thin-Film, HIT, and Mono crystalline PV systems were 5.32%, 5.1%, and 3.65%, respectively. This study provides the insight for the system installer and investor in relation to the performance and degradation of various types of PV module technologies installed under Malaysia environment.
