North Korea is 148th out of 211 countries and territories in terms of its solar potential, according to World Bank data that ranks the practical potential for solar power generation in countries around the world. A typical installation of solar panels is simple: a solar panel on a roof or balcony is connected via regulator to a large battery. During the day, electricity from the solar panel trickle charges the battery. North Korea’s Foreign Trade Bank (무역은행) has a 224-panel solar array on its roof. A small array first appeared on the roof in 2017 and was expanded in 2018. The entire installation was reorganized and enlarged to the current arrangement in a project beginning in July 2018. Researchers at the Pusan National University in South Korea have developed a hybrid rooftop photovoltaic-thermal system that can also be installed as a retrofit solution where a PV system is . North Korea is installing solar panels along the border with China to ensure that security facilities have enough electricity for nighttime surveillance, sources living in the area told RFA.
