Uma nova proposta de dimensionamento de usina solar fotovoltaica sem sombreamento no estado do Ceará

Abstract

This work aims to bring a new proposition for photovoltaic dimensioning of shadow less power plants in the state of Ceara. The proposal is based on the making of a spreadsheet using the Excel computer program. As the data contained on the energy bill and pre-established inverter models and panels are inserted in the spreadsheet, the processing of the data will occur, which will feedback the information of the power of the plant which will be installed, such as: the area required for installation; the number of panels and inverters; forecast of energy generated by the plant during the first year of operation. To validate its effectiveness, comparisons were established with the worldwide recognized computer program for photovoltaic dimensioning, PVsyst. The results were also compared with the energy generated by installed power plants, applying the statistical method of the relative mistake to show the proximity between them. The spreadsheet has been produced, tested, and improved since April 2019, measuring power plants installed in several districts in the state of Ceará. In order to provide a scientific contribution to the solar energy sector, the proposition is characterized by yet another possibility to carry out the photovoltaic solar dimensioning bearing fast and efficient results.
