It handled EPC duties and has agreed to provide maintenance services for the project, according to an online statement.
The array, which was built on a 68-hectare plot of land, is expected to generate about 20.476 GWh of electricity per year.
Prior to the completion of the 16.5 MW Jeju installation, Astronergy’s biggest project in South Korea was a 6 MW array in the city of Chuncheon, Gangwon province. It completed the array in late 2011.
The Hangzhou-based company — which manufactures monocrystalline and polycrystalline PV modules — started developing projects in 2009.
It has since installed solar in markets such as India, Japan, the U.S., South Africa, Spain and Thailand. It has also built small residential and commercial rooftop PV projects in a number of countries.
In October, it announced plans to build a 160 MW agricultural PV project in Quzhou, in China’s Zhejiang province.
In November, its parent — Shanghai-based electrical equipment supplier Chint — opened an office in Tokyo to focus on the Japanese PV market, where it has developed a handful of small projects in the 100 kW to 1 MW range.
Astronergy also announced plans in November to install 250 W solar modules and storage batteries at 8,500 post offices throughout Bangladesh, as part of a $20 million electrification plan under the national government.
