In 1938 Solvoll was sent out along with other missionaries of the Norwegian Pentecostal Outer Mission to the north of China. Solvoll resided most of the time in the areas of Xinbao'an (新保安) and Beijing. Shortly after Mao Zedong declared their seizure of power, all the missionaries were forced to leave China. Arnulf's next stop was Japan, a sunrise country. He later relocated to Taiwan, where he worked for many years and built up a missionary work of radio broadcasts, a home for those patients affected with polio, and social work for prisoners. In 1988, after forty-seven years of continuous service, Solvoll was thanked as a missionary at a party gathering in Bethel. The following year he was awarded the silver King's Medal of Merit for his long contribution to the mission.
