Estimativa de radiação solar global por um painel fotovoltaico de silício policristalino

Abstract

According to population growth on a large scale across the globe, natural resources become increasingly important in the daily lives of humans, whether in food production, technology or even in their well-being. With this, all the requirements of consumer good have as a fundamental basis for all its operation, the consumption of energy in supply to all the functionality in which we live today. Nowadays, if there is no electricity on the planet, there would be no technological advance in the day-to-day life we live in today. In this way, the use of renewable resources for electric power generation is growing on a large national and global scale. Brazil has a vast territory for the application of renewable resources, for our region of the South of Amazonas, in Humaitá, found a great capacitance in the incidence of solar radiation, in this way, low cost materials were used to estimate radiation global solar, once applying studies focused on solar radiation can contribute significantly to the meteorological branch of the region. Therefore, a mini-plate of polycrystalline silicon was used for radiation estimation compared to the values of the global solar radiation through the piranôro CM5. The application was elaborated by two assembly procedures, the first one being placed the solar cell exposed unprotected to the sun on consecutive days, presenting 60% efficacy in linear form and 73% in exponential form. The second procedure, accompanied by two light filters, resented 70% efficacy in exponential form and 75% in linear form.
