The Impact

Abstract. The presence of aerosols in atmosphere has the potential to decrease the efficiency of solar photovoltaic energy generation. The central region of Brazil presents a remarkable growth of these aerosols between March and October, when the region undergoes a period of intensive slash and burn agriculture. This paper aims to evaluate the impact of this anthropogenic aerosol on electric power generation by comparing data from geostationary satellites with photovoltaic power generation data.

Electric Sector

INTRODUCTION. The Brazilian electricity sector and parts of society are experiencing the impacts of COVID-19, which spreads throughout the world, paralyzing all or part of its activities. The reduction in electricity consumption leads to an analysis of the stability of the Brazilian energy matrix that serves different social segments. OBJECTIVE. The objective of this work was to carry out an analysis of the electric power generation sector and its standardization, the perspectives of its post-Covid-19 behaviour and the role of renewable energy sources, in particular the photovoltaic industry. METHOD. An analysis was made of the electric power generation sector and its standardization, the prospects for its post-Covid-19 behaviour and the role of the solar photovoltaic systems. RESULTS. Scenarios evaluated: updating of the regulatory framework for the Brazilian electric sector, the solar energy market photovoltaic, electricity consumption and the solar photovoltaic systems as a complementary source in this climate change scenario. DISCUSSION AND CONCLUSIONS. It is concluded that sustainable transitions on the planet, associated with economic growth, promote human development for a low carbon community.

And Performance

As the development trend of solar energy, which is a green way of energy utilization, photovoltaic power generation has been a research hotspot of solar energy utilization technologies. Using the concentrating and tracking technology to increase the illumination intensity, and obtain more electrical energy, that will reduce the cost of the photovoltaic power generation system sharply. A kind of steric and multilevel concentrator for photovoltaic generation is introduced in this paper, whose concentration ratio is 3. The operating factor of plane mirrors and performance price ratio of the system is increased for optimizing the condensation parameters and structure of the concentrator.

The Impact

<p>As solar energy share is showing a significant growth in the European electricity generation system, assessments regarding long-term variation of this variable related to climate change are becoming more and more relevant for this sector. Several studies analysed the impact of climate change on the solar energy sector in Europe (Jerez et al, 2015) finding light impact (-14%; +2%) in terms of mean surface solar radiation. The present study focuses on extreme values, namely on the distribution of low surface solar radiation (overcast situation) and high surface solar radiation (clear sky situation), since the frequencies of these situations have high impact on electricity generation.</p><p>The study considers 11 high-resolution (0.11 deg) bias-corrected climate projections from the EURO-CORDEX ensemble with 5 Global Climate Models (GCMs) downscaled by 6 Regional Climate Models (RCMs).</p><p>Changes in extreme surface solar radiation frequencies show different regional patterns over Europe.</p><p>The study also includes a case study determining the changes in solar power generation induced by the extreme situations.</p><p> </p><p> </p><p>Jerez et al (2015): The impact of climate change on photovoltaic power generation in Europe, Nature Communications 6(1):10014, 10.1038/ncomms10014</p><p> </p>
