He has been a member of ERC's national executive since 2015. At the 2006 regional election he was placed 12th on ERC's list of candidates in the Province of Lleida but the party only won three seats in the province and as a result he failed to get elected. Solé contested the 2007 local elections as a Republican Left of Catalonia-Acord Municipal electoral alliance candidate in Agramunt and was elected. He was re-elected at the 2011 local elections and became mayor of Agramunt. He was re-elected at the 2015 and 2019local elections.

In May 2019 the High Court of Justice of Catalonia summoned Solé to appear before the court on 4 June 2019 to be interrogated about charges of disobedience in relation to his role in the conduct of the 2017 Catalan independence referendum. At the interrogation Solé rejected the charges of disobedience, stating that as mayor he did not promote the referendum and that he was merely expressing his political opinions. In October 2019 TSJC judge Mercedes Armas found evidence of Solé committing disobedience, closed the investigation against him and requested that an oral trial begins. The TSJC dismissed an appeal by Solé in January 2020 and ordered that he be tried for disobedience for facilitating the referendum in Agramunt, allowing the use of public premises and hiding ballot boxes. Solé could be disqualified from holding public office for one and a half years and fined €24,000 if found guilty.
