Soltsy, whose name owes to the nearby salt water springs, was first mentioned in a chronicle in 1390 and in the following played an important role as an intermediate station on the trade route connecting Novgorod and Pskov. In 1471, the Battle of Shelon between Muscovite forces led by Ivan III and the army of the Novgorod Republic took place near Soltsy, which marked the end of political independence of the Novgorod Republic. Soltsy eventually became a part of the Moscow State. In the course of the administrative reform carried out in 1708 by Peter the Great, the territory was included into Ingermanland Governorate. In 1727, separate Novgorod Governorate was split off, and in 1772, Pskov Governorate was established. In 1776, Porkhovsky Uyezd was transferred from Novgorod Governorate to Pskov Governorate. Soltsy was the seat of Soletskaya Volost of Porkhovsky Uyezd. In August 1927, the uyezds were abolished and, effective October 1, 1927, Soletsky District was established, with the administrative center in Soltsy. Pskov Governorate was abolished as well and the district became a part of Novgorod Okrug of Leningrad Oblast. At the same time, Soltsy was granted town status. On July 23, 1930, the okrugs were abolished and the districts were directly subordinated to the oblast. Between July 13 to 16, 1941 and again from July 22, 1941 to February 21, 1944, Soltsy was occupied by German troops. On July 5, 1944, Soltsy, together with Soletsky District, was transferred to newly established Novgorod Oblast.
The main branches of industry in Soltsy are electronic industry and food industry.
