Economic and Environmental Assessment of Photovoltaic Systems in Commercial Use and Dynamic Simulation of Electricity Prices

The energy and economy interactions are so advanced that they are in today's economic literature, the amount of energy resources in countries, the amount of primary energy supply and consumption per capita and the per capita kilowatt-hours of electricity consumption have become one of the indicators for comparing the level of development of countries. Fossil fuels cause social costs through environmental pollution and the phenomenon of global warming; the average solar radiation of Kerman daily has 5.2 kilowatt-hours per square meter per day, which has the potential to use solar energy in various industrial and household sectors. The purpose of this article is to assess the economic and environmental assessment of photovoltaic systems in providing electricity to a commercial tower with an average consumption of 32000 kilowatt-hours of electricity per day in Kerman using a life-cycle cost method. In the first scenario, all system costs are paid by the consumer, and in the second scenario, it is assumed that 50% of the initial investment cost was paid by the government, and the rest would be in the form of a loan at a rate of 2% with the repayment period of ten years old. The results show that the use of photovoltaic systems in order to produce electricity under the first scenario does not have economic justification, but with the support of the government, this scheme has economic justification.
