Economic evaluation and photovoltaic electricity price modificationusing motivational approaches and needing assessment in accordance with Solar atlas of Iranian climate

The fixed pricing of selling solar electricity in the geographical area of Iran, regardless of the country's different climatic and solar conditions, leads to a reduction in production incentives. According to the atlas of the average annual solar radiation (photovoltaic), the central provinces of the country are classified into 10 groups. The base group of price correction is selected using statistical models of mode and median. Cities of Ahvaz, Bandar Abbas, Bushehr, Bojnoord, Urmia, Ardabil, Gorgan, Sari and Rasht which are among less sunshine Ing groups are using about 46% of household electricity consumption. In order to match between electricity production and consumption in different locations concerning sustainable development approach, instead of increasing the production of fossil electricity and/or increasing the length of transmission lines we can use the different purchasing price policy (price discrimination policy).According with the results of this research the level or the Internal Rate of Returnof the base group (33.15 percent), we can set the new guaranteed rates for Gilan, Mazandaran, Golestan, Ardabil, North Khorasan, West Azerbaijan, Khuzestan, Hormozgan and Bushehr as 67, 50, 36, 25, 15, 15, 7, 7, and 7 percent,respectively. Zahedan, with an internal rate of return of 36.24 and a 4-year net return on normal capital, is the most capable city in Iran in the economic evaluation of photovoltaic electricity.
