In order to minimize the installation space for maximum energy production and the income from it has been obtained for the cities of Iran.Results of return on investment for five cities of Yazd, Ardabil, Gorgan, Ahvaz and TehranIn normal andoptimal condition, it shows the speed of return on investment in Yazdand its decrease is in Gorgan.The return on investment of the planned photovoltaic system in cities depends on meteorological data, geographical location and identification of the optimal point of the objective function.also for data analysis, the planned photovoltaic system with powers of 5 and 8.6 kW in the city of Tehran has been compared, Which indicates the economic nature of the model also, the two cities of Tehran and Ahvaz are located in the same area. With the stability of the power distribution network and the reduction of the effect of blackouts in the joint operation, the energy storage of the system can be disregarded. This speeds up the return on investment and costs. Economics, system stability and electricity network are the two conditions of this model, which policymakers can, by planning and decision-making, develop this system in the country and make the country's electricity distribution network and manpower sustainable. %U https://ecoj.tabrizu.ac.ir/article_12463_c630a32f8c7a0672adfd765662e8b6aa.pdf
