In recent years, due to the fact that non-renewable energy is coming to an end, renewable energy is expected to provide a significant part of the future needs of Iran. Among these energies, solar energy can be used in a wider range of country, due to availability, proper radiation intensity, high sunshine during the year (about 300 sunny days per year), Installation in the desired power and a lot of land in many parts of the country will have a significant share. The purpose of this paper is to analyze the performance of 1 MW Arak solar power plant (Iran's first megawatt power plant) according to IEC-61724 standard using data recorded over a year (November 2016 to November 2017). The Arak Solar Power Plant was built at latitude of 34° 3', 2" north, and longitude 49° 47' 47" at an altitude of 1700 meters above sea level. The plant has the capacity of 1 MW in a 1.6-acre land with 3920 modules (1920*260 Watt Monocrystals and 2000*250 Watt Polycrystals) in 200 structures and four inverters (each with a capacity of 250 kW). The information of this power plant is recorded in fifteen-minute intervals, which according to IEC-61724, this power plant is in the class B and we can do one-year performance analysis. In this paper, the performance parameters of the system are presented, also a table for comparison with other power plants in some parts of the world has been created.
