Solar energy in Korea is mostly used to heat single homes, but now the nation has its first regional solar heating system.
On Friday, the Korea Institute of Energy Research and the Korea District Heating Corp. will hold an opening ceremony for a homemade regional solar heating system at the corporation's office in Bundang, Seongnam city in Gyeonggi Province.
The system includes the largest solar panel in the country, measuring 1,069 sq. m. The panel will reheat water from an existing regional heating system to 90 degrees Celcius and reintroduce it to the system.
According to the results of a test run, the solar system will be able to provide heat for 40 to 50 households. It is expected to save W30 million (US$1=W940) and 82 tons of oil per year while reducing annual carbon dioxide emissions by 138 tons.
Researcher Baek Nam-choon of the Korea Institute of Energy Research said, "The solar heating system is able to heat water in the most efficient way by using two kinds of solar panels and adjust the volume of water it heats according to the strength of the sunlight."
