Technical-economic feasibility of designing a 10 MW solar power plant of KavirTire Company in Birjand city of South Khorasan province using RET Screen software

Due to the absence of pollution and the availability of sunlight in different parts of the globe and tropical regions, the production of electrical energy through solar radiation has received much attention from researchers. In this research, first, the trend of increasing the share of renewable energies, including solar energy, in the production of electrical energy in the world has been investigated. Then, while analyzing the potential of Iran and the city of Birjand for the construction of photovoltaic power plants, its components and technical considerations have been taken into consideration. In the following, the future options for using the photovoltaic power plant in the Kavirtire factory located in Birjand city are examined, in the following, the technical and economic model for the construction of a 10MW photovoltaic power plant to supply the electricity required by the Kavirtire factory by RETscreen software is designed and developed. Then, considering the existing assumptions, the economic analysis of the project is done in the usual ways, and the results of the economic analysis indicate that according to the calculated internal rate of return and the positive balance of the net present value, the present project is financially It is completely justifiable and the risk of the investment return time of the project is equal to 7.3 years and the return time of the investor is 8.4 years and the project risk is 10%.
