Phoenix Solar AG emerged from an initiative of the "Bund der Energieverbraucher e.V" (English: "Cooperative of Energy Consumers"), which was originally started in 1994.

Since November 18, 2004, the "Phoenix SonnenAktie" (shares of the company) have been traded on the OTC stock exchanges in Munich, Frankfurt, Berlin / Bremen and Stuttgart.

Since June 2007 Phoenix Solar shares were listed in the ÖkoDAX and since March 2008 they are a constituent of the TecDAX stock market index.

In July 2013 the company started building a 38.6-megawatt photovoltaic plant on a former cotton field in Georgia, based on a contract with Silicon Ranch Corporation.
