Analysis on the Generation Characteristics of the 1MW PV Plant in the Jeju Island

Abstract

-An 1 MW PV plant constructed at the Ara campus of Jeju National University in May 2012, which was the biggest roof-top PV plant in Korea and the biggest PV plant in Jeju Island at the time. In this paper the generation characteristics of the plant was analyzed on the basis of the data obtained during 2 years.The amount of electrical energy generated by the plant in July was less than those by the PV plants of the other regions except Jeju Island in Korea, which might be due to the long rainy season started in June earlier than the other regions. But those generated by the plant during summer season was more than those during autumn, which was different trend from the other regions in Korea. And the yearly capacity factor of the pant was 12.7% which is low relatively in Korea.The loss of the transformer in the plant, as expected, was shown to increase according to increasing the electrical energy generated by the plant. Summer's transformer loss was greater than spring's one in spite of summer's generated electrical energy less than spring's one, which tells that the transformer have the need to strengthen its cooling in summer.
