The Impact

The facile conversion of sunlight into electricity of a solar-energy system is predominantly associated with the sun's irradiance as well as myriad environmental/climatic factors and photoactive material employed. However, the impact of other external factors associated with solar-rich geographical location (India) can be more influential on system performance. Among these, dust is oft-times an overlooked or understated issue that can be a major stumbling block in a solar panel's output performance. This chapter provides an insight of dust's impact on photovoltaic modules and evaluates mitigation of power loss and other performance parameters due to dust accumulation. In addition, this chapter analyzes dust's impact on the real-time data collected for 46 inverters with total 114819.30 kWh productions in a month with an average of 4416.13 kWh/day. The research further reviews key contributions to the understanding and performance effects of dust on solar module and presents an inclusive literature survey/assessment.

The Impact

The northern and border regions are remote from the main economic centers of the country. Geographical location is not only a limitation, but also a competitive advantage, which is determined by proximity to economically developed national economies and greater opportunities for interaction. The main goal of the study is to assess the impact of the geographical factor on development dynamics. The object of the study is the border northern regions of the NWFD, Russia and Finland. The study uses a set of methods and tools to analyze the dynamics of the development of territories with a border and northern location. Within the framework of this article, analysis is carried out on the basis of statistical methods of research. Analytical work is based on the information base of Rosstat and data from Internet sources. As part of the study, the level of Russian-Finnish relations in the investment component vector is determined. An assessment of foreign investment in the context of federal districts was made, which made it possible to distinguish the influence of the geographical location factor. Indicators of labor productivity in the national and foreign sectors in the regions of the North-Western Federal District have been determined. The dependence of the productivity indicator on the geographical location of the territory was investigated.The conclusions of the Territory, having a geographical position favorable for foreign economic activity, are not able to fully take advantage of its competitive advantages. The study identified a low level of dependence between geographical location and performance. The results will help to shape the directions of increasing this indicator and can be used in strategic and program documents.

Insight Into

Abstract Corporate governance is viewed as an important, essential, and most significant factor for well-functioning of firms. Recent academic work and policy analyses have given insight into the governance problems in banks exposed to the financial crisis and suggest possible solutions. This paper begins by explaining the importance of corporate governance and its impact on risk taking and bank performance based on the theoretical background relevant to the corporate governance of banks. I combine the literature that looks at three areas of governance: ownership structure; board structure; and risk management, with the literature on risk-taking and performance effects in order to better assess the weight of the impact that these governance mechanisms have on both performance and risk. The paper concludes by highlighting the areas where further research is needed.

The Impact

Solar photovoltaic (PV) electricity generation is expanding rapidly in China, with total capacity projected to be 400 GW by 2030. However, severe aerosol pollution over China reduces solar radiation reaching the surface. We estimate the aerosol impact on solar PV electricity generation at the provincial and regional grid levels in China. Our approach is to examine the 12-year (2003–2014) average reduction in point-of-array irradiance (POAI) caused by aerosols in the atmosphere. We apply satellite-derived surface irradiance data from the NASA Clouds and the Earth’s Radiant Energy System (CERES) with a PV performance model (PVLIB-Python) to calculate the impact of aerosols and clouds on POAI. Our findings reveal that aerosols over northern and eastern China, the most polluted regions, reduce annual average POAI by up to 1.5 kWh/m2per day relative to pollution-free conditions, a decrease of up to 35%. Annual average reductions of POAI over both northern and eastern China are about 20–25%. We also evaluate the seasonal variability of the impact and find that aerosols in this region are as important as clouds in winter. Furthermore, we find that aerosols decrease electricity output of tracking PV systems more than those with fixed arrays: over eastern China, POAI is reduced by 21% for fixed systems at optimal angle and 34% for two-axis tracking systems. We conclude that PV system performance in northern and eastern China will benefit from improvements in air quality and will facilitate that improvement by providing emission-free electricity.
