Abstract

The participation increase of photovoltaic systems in the Brazilian electrical matrix comes inducing the advancement of research, aiming the improvement of solar technology and mitigation actions to ensure the expected performance of these systems. The meteorological factors are those that most influence the performance of photovoltaic systems. Furthermore, the weather condition of the installation site affects considerably the accumulation of dirt on the solar modules, so that part of the incident radiation is not transmitted. This paper aims the compositional and structural identification of dirt deposited on photovoltaic modules located in different cities in the state of Minas Gerais. Initially,it was made a microstructure analysis of particles comprising the deposited material. Then the weather VI Congresso Brasileiro de Energia Solar – Belo Horizonte, 04 a 07 de abril de 2016 conditions were identified by associating them with the characteristics of dirt of the features found on site. Finally, some mitigation actions were proposed against possible impacts of dirt on PV modules installed in the cities under review.

米纳斯吉拉斯州气候区光伏组件上沉积污垢的物理化学特征

光伏系统在巴西电力矩阵中的参与度增加，导致了研究的进步，旨在提高太阳能技术和缓解措施，以确保这些系统的预期性能。气象因素是对光伏系统性能影响最大的因素。此外，安装地点的天气条件对太阳能组件上污垢的积累有很大影响，因此部分入射辐射无法传输。本文旨在对位于米纳斯吉拉斯州不同城市的光伏组件上沉积的污垢进行成分和结构鉴定。最初，对沉积材料的颗粒进行微观结构分析。然后，通过将2016年4月4日至7日在贝洛奥里藏特举行的第六届巴西能源太阳能大会的天气条件与现场发现的特征的污垢特征相关联，确定了这些条件。最后，针对所审查城市中安装的光伏组件可能受到的污垢影响，提出了一些缓解措施。
