Aftab Shargh (meaning “Sunlight of the East” in Persian) will become Iran's largest and most technologically advanced solar power plant when it reaches full capacity of 600 MW by March 2027. The power plant was built by Mobarakeh Steel Company, the largest steel producer in West Asia. Iran, with its vast solar potential and pressing energy demands, is poised to transform its energy landscape through renewable energy, particularly solar photovoltaic (PV) and energy storage. Blessed with an average annual solar irradiation of 4. 5 kWh/m² and up to 2,200 kilowatt-hours of solar. The recent opening of Iran's largest solar power plant, Aftab Sharq, in central Isfahan province, marks a significant milestone in the country's pursuit of self-sufficient renewable energy technology. Iranian President Masoud Pezeshkian used a video link on Thursday to inaugurate a 120-megawatt (MW) unit of the Aftab Shargh solar farm in Isfahan province. The country's first all-in-one solar power substation, comprising an inverter, transformer, low- and medium-voltage switchgear, and protective equipment was unveiled for the first time on May 28, at Iran Transfo Zanjan's Substation Development Company.
