Considering the geographical location and climatic conditions of Iran, solar energy can provide a considerable portion of the energy demand for the country. This study develops a two-step framework. In the first step, the map of unsuitable regions is extracted based on the defined constraints. In the next step, in order to identify the suitability of different regions, 11 defined criteria, including solar radiation, average annual temperatures, distance from power transmission lines, distance from major roads, distance from residential area, elevation, slope, land use, average annual cloudy days, average annual humidity and average annual dusty days, are identified. The relative weights of defined criteria and sub-criteria are also determined applying fuzzy analytical hierarchy process (FAHP) technique. Next, by overlaying these criteria layers, the final map of prioritization of different regions of Iran for exploiting solar photovoltaic (PV) plants is developed. Based on Iran's political divisions, investigation and analysis of the results have been presented for a total of 1057 districts of the country, where each district stands in one of the five defined classes of excellent, good, fair, low, and poor level. The obtained data indicate that 14.7% (237,920 km 2 ), 17.2% (278,270 km 2 ), 19.2% (311,767 km 2 ), 11.3% (183,057 km 2 ), 1.8% (30,549 km 2 ) and 35.8% (580,264 km 2 ) of Iran's area are positioned as excellent, good, fair, low, poor and unsuitable areas, respectively. Moreover, Kerman, Yazd, Fars, Sisitan and Baluchestan, Southern Khorasan and Isfahan are included in the regions as the most excellent suitable provinces for exploiting solar PV plants.

“…The government of Vietnam has therefore shown interest in solar generation, wind energy, and biomass power and while there is a great potential for wind and biomass-generated energy, the development of solar power generation facilities is particularly appropriate for Vietnam and especially so in the Central Highlands and Southern areas [17]. The total duration of sunshine in the Central Highlands is from 2000 to 2600 hours per year [18], and 1kWp of solar energy will generate at least 2000kWh electricity per year.…”

Abstract Background: There are many constraints on the use of fossil fuels and, many countries have, therefore, conducted research relating to alternative energy resources to replace conventional fuels. On 31 January 2019, the Vietnamese Ministry of Finance enacted a preferential policy relating to the installation of under-50kWp rooftop solar projects. The Central Highlands of Vietnam has a high potential for solar power generation due to the duration of sunshine it enjoys, and the development of both rooftops solar and solar farms is appropriate for the region. The study reported investigated the economic efficiency of smart-grid rooftop solar electricity systems (SG rooftop PV) in the Central Highlands of Vietnam in light of the different levels of retail electricity pricing in Vietnam and the implementation of a feed-in-tariff system. The research reported in this paper will be useful for many groups of stakeholders, including electricity consumers who intend to install rooftop solar panels on their houses, companies who supply SG rooftop PV, and policymakers, who can use the findings relating to SG rooftop PV to adjust the retail price of electricity during different periods.Method: Financial indicators were calculated based on the net present value, payback period, internal rate of return, and the number of hours of sunshine in the Central Highlands of VietnamResult: The study’s results show that the electricity price level affects the economic efficiency of SG rooftop PV. In particular, SG rooftop PV installed to satisfy higher levels of electricity consumption, which attract a higher retail electricity price, result in greater benefits, especially when domestic electricity consumption exceeds 400 kWh, at which level the retail electricity price is at the highest level. In this case, people who install SG rooftop PV and use all the electricity to satisfy domestic consumption will recoup their investment in only 4 years and thereafter will enjoy free electricity. Conclusion: All the financial indicators derived from this research show that people in the Central Highlands of Vietnam can derive benefit from installing SG rooftop PV, whether they sell all the electricity output to the grid or use the power output to satisfy their domestic demand.

“…There is the problem that the position of the accurate failure PV module must be manually displayed on the workstation in the drawing by the operator on the position corresponding to the photographed thermal image file. As the shape of installed solar modules is very similar, there is a restriction that it is not possible to identify the exact position of the solar module unless the photographed image data are accurately grasped [24,25]. The resolution difference between thermal camera image and RGB image has many constraints for utilizing both images together.…”

Photovoltaic (PV) power generation facilities have been built on various scales due to rapid growth in response to demand for renewable energy. Facilities built on diverse terrain and on such a scale are required to employ fast and accurate monitoring technology for stable electrical production and maintenance. The purpose of this study was to develop a technology to analyze the normal operation and failure of solar modules by acquiring images by attaching optical and thermal infrared sensors to unmanned aerial vehicles (UAVs) and producing orthographic images of temperature information. The results obtained in this study are as follows: (1) a method of using optical and thermal infrared sensors with different resolutions at the same time is able to produce accurate spatial information, (2) it is possible to produce orthographic images of thermal infrared images, (3) the analysis of the temperature fluctuation characteristics of the solar panel and cell showed that the abnormal module and cell displayed a larger temperature change than the normal module and cell, and (4) the abnormal heat generation of the panel and cell can be accurately discerned by the abnormal state panel and cell through the spatial distribution of the temperature. It is concluded that the inspection method of the solar module using the obtained UAV-based thermal infrared sensor can be useful for safety inspection and monitoring of the rapidly growing solar power generation facility.Since the mid-1970s, the Republic of Korea has started to apply solar power to homes. In the early days, solar panels were mostly used for hot water. In 2000, solar PV applications diversified, extending to household, industrial, agricultural, lake, and reservoir applications. Republic of Korea has been mainly used to utilize mountainous areas, which occupy 63% of the entire country. Many solar power plants are generally operated by using large flat terrain, but many facilities have been applied to sloped terrain conditions. In recent years, the number of PV power generation facilities installed on the water, i.e., reservoirs and lakes, has increased. Facilities located on such terrain and water incur heavy cost and require a lot of manpower to check periodic monitoring and problematic solar panels, and there is a high risk of safety problems. In order to operate the solar power plant efficiently, it is necessary to have not only a solar panel but also equipment for monitoring and maintaining the solar power plant [4].PV power plants are affected by various factors that can damage or reduce their efficiency. Selecting an optimal location for a power plant, one that maximizes power generation efficiency, is important in reducing power-generation and maintenance costs [5]. Once installed, the first time damage occurs to any part, the cell will overload and cause abnormal heat generation. After that, the entire module is short-circuited, and the overall output is lowered. Defects and losses that can occur in solar panels are caused by various factors. Decrease of po...
