Desempenho de um sistema solar fotovoltaico com diferentes inclinações e orientações azimutais em cidades da Paraíba

Abstract

<p>The Sun is the main source of energy for the Earth. The conversion of solar to electric energy can be done through photovoltaic systems, whose performance depends on variables such as slope angle and azimuth orientation. The objective of this project was to evaluate the annual production of electric energy according to the function of the angles of inclination and azimuth orientation for a residential photovoltaic system connected to the grid in six municipalities of Paraíba. The analysis was performed via a System Advisor Model simulation for a system with a capacity of 1500 Wp. The reference system considered in this study was oriented to the geographic north and the slope was equal to the local latitude. The variation of the angle of inclination of the module was considered at intervals between 0 ° and 90 ° and the azimuthal angle ranged from 0 ° to 360 °. The annual production of energy in each system positioning was normalized by the yield of the reference system to obtain the losses for each orientation. Results indicated that concerning the energy produced by the system in the horizontal condition and regardless of the azimuthal angle, the losses did not exceed 1% in relation to the reference system. It was also observed that there is a wide range of slopes and orientations so that a photovoltaic arrangement can be applied with the minimum loss of electricity generation in relation to the reference system.</p>

Solar energy available and energy generated in photovoltaic systems in different inclinations and orientations of roofs of buildings

“…The results found in relation to orientation and inclination through the results of the analysis support the discussion. The ideal inclination behaves as highlighted in the study by Nóbrega, Lima, Melo, Gonçalves and Wanderley Neto (2018). In the proposed work, it is possible to verify the results of the annual energy production as a function of the variation of the angle of inclination and azimutal orientation of the photovoltaic panels simulated in the SAM and normalized by the ideally oriented system (Nóbrega et al, 2018).…”

“…The analysis of the results of the Nóbrega et al (2018) simulations shows that the energy produced by the panel for the 10° slope is numerically higher than a panel with a 20° inclination. However, statistically the energy values produced for both slopes are equal.…”

“…The city of Cascavel-PR has latitude S 24º57'21'', this being the ideal slope with true north orientation for the highest Global Solar Irradiation Incident and power generation. Therefore, data from Nóbrega et al (2018) show that the highest incident Global Solar Irradiation occurs at the 10° slope, with cities in low latitudes analysis around 5 to 10° S. Therefore, the ideal slope is 10°. Note the variability of the slope and ideal orientation according to the geodesical coordinate of the locality.…”

Desafios do desenvolvimento rural sustentável em Iporã-PR: influências na implementação e produtividade dos sistemas fotovoltaicos conectados à rede

“…Desse modo, observa-se a evidente redução na irradiação solar em dias nublados ou chuvosos. Assim, a energia produzida pelos painéis fotovoltaicos também depende das condições meteorológicas e de posicionamento geográfico, evidenciando a necessidade do estudo solarimétrico sobre o local de instalação(VILLALVA, 2015).Sabe-se que quanto maior a latitude do local de instalação do sistema fotovoltaico, maior será a influência das estações do ano e maior a tendência a ter menos produtividade energética(NÓBREGA et al, 2018). Mesmo o Paraná estando sua maioria entre as latitudes -23º e -26º, suas porções Norte, Noroeste e Oeste possuem ótimos índices de produtividade fotovoltaica devido às suas condições climáticas, assim como pode ser observado na Figura 4.…”

Análise Da Integração De Sistemas Fotovoltaicos Em Edificações Militares Em Diferentes Climas

“…Dois dentre eles destacam-se por terem sido realizados no clima de Curitiba, que é uma das cidades objeto deste estudo: sistema fotovoltaico conectado à rede capaz de gerar 4,37 GWh na UFPR (MARIANO, 2017) e sistema fotovoltaico de 45 kWp, gerando 60 MWh por ano para a UTFPR com a instalação dos módulos no telhado (KRASNHAK; JUNIOR, 2019). Além disso, diversos estudos têm avaliado o desempenho dos sistemas fotovoltaicos por meio de critérios de mérito em climas brasileiros e a integração dos módulos às edificações (DÁVI et al, 2016;DO NASCIMENTO et al, 2020;GASPARIN;KRENZINGER, 2017;MELLO, 2016;NÓBREGA et al, 2018;SORGATO;SCHNEIDER;RÜTHER, 2018).…”
