As Iran is rich in oil and gas resources, renewable energy was known as a luxurious source of electric power generation for a long time. New policies and targeted subsidy reform plan for fossil fuel products have changed the view of decision-makers and energy sector investors toward renewable energy resources. According to the climatological studies, two-thirds of Iran's land has three hundred sunny days which indicates great potentials for providing solar energy. This paper deals with small-scale solar energy potentials in different cities of Iran. The considered solar systems are based on the combination of photovoltaic panels in order to obtain the nominal values of 1, 5 and 10 kW for 15 selected cities of Iran. Design of the photovoltaic (PV) systems is carried out based on optimum fixed tilt angles of the panels and efficiency variation due to the temperature changes of different locations. The final decision on financial assessment of the mentioned solar PV projects is based on different concepts of engineering economy such as rate of return (ROR), present worth of benefit and cost (PWB, PWC), extra investment analysis, levelized cost of energy (LCOE). The amount of calculated income and the expected benefit are also investigated under certainty and uncertainty of guaranteed solar electricity purchase tariff in a 30-year project lifetime.

Solar energy plays a crucial and high-priority role in protecting and maintaining our future environment. One of the most important and outstanding factor in building a power plant is how to choose the appropriate and suitable site for solar power plants. The purpose of this research is to investigate the most felicitous locations in order to establish the photovoltaic power stations in Iran.it is highly recommended to closely consider the economical and geographical conditions. The required data were mostly obtained from satellite images and ground measurements. The principle in this paper forms some effective factors made up of in site selection and developed some guidelines about how to divide them into four categories including the value of solar radiation on earth's surface, the economic features, the technical factors and geographical considerations. It is extremely necessary to recognize the need to closely examine an important issue that these factors were analyzed and weighted by Analytical Hierarchy Process (AHP) and then the potential map was extracted. An understanding and appreciation of results represent appropriate locations namely Fars and Sistan and Baluchistan provinces which have higher potential to build Photovoltaic power plants. Ultimately, through research, it has been developed a model and map with maximum efficiency for gaining a deeper understanding of the most suitable location for the fixed panel power plant which was obtained.

This paper introduces the resource, status and prospect of solar energy in Iran briefly. Among renewable energy sources, Iran has a high solar energy potential. The widespread deployment of solar energy is promising due to recent advancements in solar energy technologies. Therefore, many investors inside and outside the country are interested to invest in solar energy development. Iran’s total area is around 1600,000 km 2 or 1.6×10 12 m 2 with about 300 clear sunny days in a year and an average 2200 kW-h solar radiation per square meter. Considering only 1% of the total area with 10% system efficiency for solar energy harness, about 9 million MW h of energy can be obtained in a day. The government’s goal on 2012 was to install 53,000 MW capacity plants for electricity generation. To reach this goal, it was assumed that the new gas-fired plants along with the hydroelectric and nuclear power generating plants could be financed by independent power producers including those of foreign investment. Based on the fifth 5 year Socio-economic and Cultural Development Plan, the private sector was expected to have a share of at least 270 MW in renewable energy development. The existing small capacity solar energy plants are in Shiraz, Semnan, Taleghan, Yazd, Tehran and Khorasan. Based on the specified available solar trough technology, solar area, average solar hours and average solar direct irradiation, the technical potential of solar electricity was estimated to be 14.7 TWe. Under the current energy policies, the combined solar, wind and geothermal power plants are economically viable. These huge RES’s potential can be realized assuming the availability of technology, investment capital, human expertise and the other resources along with a long-term driven renewable energy policy. Due to high growth rate of electricity demand in Iran, the nominal installed capacity has increased by 8.9% per annum during 2001–2007. In the reference scenario, the share of RES in total installed electricity capacity is expected to be about 2% in 2030. It is expected that the cumulative RES installed capacity will reach 2.8 GW in 2030. This requires more than 2800 million US dollar investment during 2010–2030. [ABSTRACT FROM AUTHOR]

Environmental and socioeconomic challenges facing many hydrocarbon-rich nations could help them evolve from hydrocarbon-based (black) into renewables-based (green) economies. In this paper, we present a case study for application of this Black Into Green (BIG) method for Iran. We show that with international cooperation Iran could indefinitely meet its energy and freshwater needs by leveraging large-scale renewable energy harvesting systems integrated with seawater pumped storage hydropower, reverse osmosis desalination, and enhanced distribution systems. This BIG transition could be facilitated by allocating a significant portion of Iran's potential hydrocarbon-based income to acquire, develop, and deploy renewable energy technology that utilizes Iran's immense solar and wind energy potential. Our analysis shows that developing just 1% of identified sites would provide over 30 TWh of annual renewable electricity generation and storage, and 221 million m 3 /day of renewably-powered desalination capacity to meet the freshwater needs of over 85% of its population. In addition to providing renewable energy design and manufacturing technology, the international community could also work with Iran to help evolve its nuclear power program toward small modular reactors for baseload power generation. Such an arrangement would contribute to regional and global security, and greatly reduce the Middle East's carbon emissions of which Iran is the largest emitter. Results from this holistic approach could then serve as a model for the world economy to work with other resource-rich nations to reduce their environmental impact while modernizing their economies and helping them achieve the socioeconomic goals outlined in the UN's Brundtland report. • Presents strategy for a sustainable economy to emerge from the COVID-19 pandemic. • Case study for Iran with oil (black) exchanged for renewables (green). • Wind and solar energy with coastal pumped storage hydro and reverse osmosis. • 1% of viable sites could supply Iran with 10% of power and 45% of freshwater needs. • Distributed economic and environmental benefits meet UN sustainable development goals.

Along with the increasing rate of using renewable energies, following the finite amount of fossil fuel resources, and the associated pollution of these non-renewable energies, photovoltaic systems have recently achieved widespread acceptance to harness solar energy in the last decades. Since photovoltaic systems have a limited lifespan and cannot be used after a while, it seems imperative to pay attention to recycling and sustainability in the supply chain network design of these systems. In this respect, this paper first reviews the photovoltaic systems literature systematically. Thereinafter, a multi-objective, mixed-integer non-linear optimization model is deployed to design a photovoltaic supply chain network addressing the system's associated costs, environmental impacts, and social values. The concerned model also considers a reverse flow in addition to the typical forward flow in the proposed supply chain for special environmental and social issues. Likewise, to optimize the presented multi-objective model, the augmented ε-constraint method is employed, being capable of warranting the Pareto optimal solutions. Eventually, the model's efficiency is illustrated by discussing a real-world case in Iran, through which prominent managerial results are acquired. • The photovoltaic systems literature is systematically reviewed. • A multi-objective, mixed-integer non-linear programming model is proposed to design a sustainable photovoltaic supply chain network. • The concerned model is able to consider a reverse flow in addition to the typical forward flow in the proposed supply chain. • To solve the proposed multi-objective model, the augmented ε-constraint method is deployed. • The efficiency of the model is illustrated by discussing a real-world case in Iran.
