One of the current challenges of the world is climate change and environmental pollution, which is one of the major consequences of fossil fuel consumption all over the world. To tackle this challenge, the use of renewable energies such as solar energy, especially in urban areas that have a significant portion of energy consumption, can be a remarkable solution. Considering the challenges of electricity supply in Iran's mega cities and emphasizing the existence of unused spaces such as rooftops of the buildings in urban aria, in this article, a solar photovoltaic power plant is simulated on a hypothetical building using PVsyst software in Mashhad city. By using criteria such as net present value, internal rate of return and payback period based on fuzzy approach, financial feasibility of the system will be calculated. The results of this study showed that a 5.5 kW photovoltaic system with grid connection type on a rooftops with area of 70 square meters without shading in Mashhad city with annual production of 9070 kWh per year has a fuzzy net present value between 1/371 to 1/776 billion Rials, the internal rate of return between 29 and 32 percent and payback period between 3.5 to 3.5 years. Therefore, the project is financially acceptable. Considering the high cost for the construction of this system, the suggestion is that the policy-makers should provide suitable credit facilities for the applicants and reduce the cost of the production of required equipment, by supporting the manufacturers and knowledge-based companies in this field.

1- INTRODUCTION
The adverse economic, social and political consequences of poverty have prompted governments to put improving the condition of the poor at the top of their priorities. Therefore, proper understanding of poverty and the factors affecting it has importance. But the important issue in this regard is the various definitions related to poverty, which are different depending on different approaches, including its regionality, and this issue creates the mentality that whether the phenomenon of poverty (for example, based on this approach) is actually. It is a regional and geographical category, in other words, the factors affecting poverty are different in different developed and developing regions (depending on the geographical situation of that region), or is poverty an international phenomenon and the factors affecting it are the same everywhere?
2- THEORETICAL FRAMEWORK
One of the basic issues of recent societies, which is a serious obstacle to development and progress, is poverty, which according to the 2030 report on sustainable development of the United Nations, its elimination is considered one of the 17 primary goals of sustainable development). Poverty is a major concern for policy makers; because its occurrence is directly related to the well-being of the population. In addition in economic aspects, the poverty situation in any society is also important in political and social dimensions, and any economic approach to poverty will inevitably have political and social consequences. Despite extensive studies on poverty, there is still no prevailing consensus on the main factors affecting poverty. Poverty has been looked at from an economic point of view and has attributed only economic approaches to itself in such a way that its main concept is only the lack of individual and household income compared to basic living standards. But this concept, since 1981, with the definition of poverty by the World Bank as the loss of an opportunity and not getting another opportunity as an alternative, including life, social, economic conditions, etc., took on a different definition. In Sen’s initial studies in 1982 and 1985, Sen proposed the concept of poverty in a more complete way, according to which, poverty is not only a lack of income, but also the lack of a fixed set of people's life capabilities, which some how. Deprivation refers and of course deprivation itself is a relative concept whose meaning is different in different places and times. Therefore, with a deeper insight into poverty, this category includes all types of deprivation, including economic, social, political, cultural, etc. The aforementioned deprivations are different, the poverty situation is also different in different societies.
3- METHODOLOGY
In this article, poverty and the factors affecting it have been investigated in different developed and developing regions and according to different geographical conditions. The method used in this research, in order to provide comparative models, is the ARDL panel method and the software used is Eviews 9, and the research data is extracted from the World Bank. The study areas include 30 countries (15 countries in the developing regions of the Middle East and North Africa and 15 countries in the developed regions of Europe and Central Asia). First, this study examines the impact of factors affecting poverty in macro and at the level of developed and developing regions. Then, by analyzing the impact of each region on poverty, it examines the issue of what effect does the geography of the region have on poverty? And is poverty in the regions a function of the geographical situation or not? In other words, are the factors affecting poverty different in different regions (depending on the geographical situation of that region) or is poverty an international phenomenon and the factors affecting it are the same everywhere in the world?
The model used in this research, according to the theoretical foundations and based on the model of Dano-Andonso and Sylvester (2016), is as follows:
POVit: poverty index of region i in time period t (in the current research, the percentage of people with a daily income of less than 1.9 dollars is known as poverty index); FDit: financial development index of region i in time period t (CPIA financial development index is proposed as this index); GDPit: GDP growth rate (in terms of purchasing power parity) of region i in time period t, which indicates the wealth level of the studied region; Xit: control variables of region i in time period t, which include inflation rate (INF), trade ratio (sum of exports + imports) to GDP (TRADE) and UE: unemployment rate; Therefore, the final model will be as follows:
4- RESULTS & DISCUSSION
Based on the results, it is clear that in the developing countries of the Middle East and North Africa, the coefficients of all the variables except the financial development variable have a high significance, so that the unemployment rate variable has a coefficient of (0.153) at the level of 5% and the gross production growth rate variables. Domestic with coefficient (-0.285), trade to GDP ratio variable with coefficient (-0.058) and inflation rate with coefficient (0.241) are significant at 1% level. On the other hand, in the developed countries of Europe and Central Asia, the coefficients of all variables except the unemployment rate variable are significant, so that the financial development variable with the coefficient (-0.213), GDP growth rate variable with coefficient (-0.213). The variable of trade to GDP ratio with coefficient (-0.117) and inflation rate with coefficient (0.098) is significant at 10% level. According to the results obtained for the countries of developing and developed regions, it is clear that:
The estimated models are significant and the results related to most of their coefficients are also highly significant. Only the financial development variable in the developing countries of the Middle East and North Africa is meaningless, which indicates that the financial development index has no effect on poverty in less developed regions. From another point of view, the reason for the meaninglessness of this index can be seen in the underdevelopment or in a better way, the inefficiency of the financial sector in the Middle East and North Africa regions. The signs of all the coefficients related to the independent variables of inflation rate, international trade, GDP growth, financial development and unemployment are the same in all models, except for the models in which the index is not significant. In other words, the increase in inflation and unemployment in both developed and developing regions (regardless of the geographical situation) increases the level of poverty; Meanwhile, improving financial development, economic growth and international trade reduces poverty. In the context of the error correction relationship, the value of the estimated ECM coefficient is higher for the group of developed countries. In other words, if there is a shock to poverty, it will return to its long-term trend faster in mainly developed countries than in less developed countries. This issue is probably due to more economic stability in countries with a higher level of development than in less developed countries.
5- CONCLUSIONS & SUGGESTIONS
The variables of economic growth, international trade, inflation, unemployment and financial development are the most important factors affecting the poverty index in developing and developed countries. However, the indicators of inflation and unemployment increase the level of poverty and the improvement of financial development, economic growth and international trade reduces poverty. Meanwhile, the negative effect of the economic growth coefficient on poverty, in both groups of developing and developed countries, indicates the confirmation of Stiglitz's trickle-down effect theory that economic development reduces poverty, and it is suggested that economic development and increased production growth The country has increased the wealth of the rich and in this process, a part of their wealth increase is gradually transferred to the poor. For example, as the wealth of the rich increases, the demand for production factors, especially the labor force of the poor, increases, and as employment increases and unemployment decreases, poverty decreases (the direct relationship between the unemployment rate and poverty also confirms this importance). The variables of economic growth, unemployment and inflation have had the greatest impact on poverty in different regions. In other words, poverty in different regions is mostly an economic category and other different approaches related to poverty are placed in the next levels of importance. In addition, this category, along with the different influence of governments on the level of poverty in developing and developed countries, is a good confirmation of the theory of political economists in relation to poverty at the international level, who state that the poverty of societies is focused on the mutual relationship between politics and economy and the role of governments and in general, the role of human action and especially the economic and political leaders, is in the poverty of the regions.
