The first loop of silicon industry chain is to extract industrial silicon from silica which the executive and construction operation of Araz Industrial Silicon Factory with the annual capacity of 50,000 tones has begun form Shahrivar 1399 (August 22 – September 20, 2020) and the first products of this company will enter the market in Spring of 2022. The land for implementing the project is located at 2nd Phase of Khoy Industrial Park and its area is more than 171,000m2. The second loop in silicon industry chain of Araz Silicon Industries Company is to construct a silicon production factory with the annual capacity of 10,000 tones and this company has the construction of a silicon wafer production factory with the annual capacity of 1,000 Mega Watt in agenda as well. One of the objectives of the company is to construct a large-scale solar power plant. This company, after production of solar cell and panel with the annual capacity of 750 Mega Watt, has the construction of a solar power plant with its produced panel in agenda. In this line, Azar Silicon Industries Company has signed a memorandum of understanding with Renewable Energy and Energy Efficiency Organization (SATBA) for constructing and operating a 2,500 Mega Watt solar power plant within maximum period of 4 years. In case of cooperation of Tavnir Company and Regional Electricity Companies, this company has targeted the construction of a 500Mega Watt solar power plant in 2022.

Considering that resources of fossil fuels are limited and using these fuels for generating energy is polluting, this has increased the tendency for using renewable energies. Resources of renewable energies that are used commercially include the sunlight, wind, rain, tide, waves, geothermal and biomass. The solar energy is a main source of renewable energy and techniques of photovoltaic systems, concentrated solar energy and solar water heating are used to harness them. Solar panels can be categorized in three general groups based on production method of their solar cells. These three categories include monocrystalline, polycrystalline and thin-film. Monocrystalline and polycrystalline categories function like each other and have similar technology. Both of them use silicon as semi-conductor to generate electrical energy. The major difference between these two types is in the process of producing their wafers. To produce monocrystalline wafers, monocrystalline ingots are used. Whereas, to produce polycrystalline wafers, melting silicon crystals and producing polycrystalline ingot are used.
