ABSTRACT
HIGHLIGHTS Comparative study of the operation of eight real cases of systems installed in Paraná. There is a convergence between the values estimated by the Atlas and the ones calculated. It was possible to identify the cities that presented the greatest figures of merit.
Abstract With the development of renewable energies in the world, there is also an increase in solar photovoltaic systems globally. In Brazil, and in the state of Paraná, there is an exponential growth of this form of energy generation, which causes the necessity to study the performance of the installed systems. Therefore, this article analyzed eight photovoltaic systems installed in the state of Paraná, under the aspect of figures of merit parameters, through calculations of final yield, performance ratio and capacity factor. In addition, the calculated values were compared to the values estimated by the Solar Energy Atlas of the State of Paraná. As a result, the largest average differences in final yield, between the calculations and the Atlas, were found in the cities of Cascavel, while the smallest were observed in Goioerê.

Abstract With the increasing of energy demand in Brazil and the unprecedent popular support for the use of energy sources with low environmental impact, the market for photovoltaic energy has become progressively relevant. Thus, it is of strategic importance to gather information of the solar resources either for a particular location or a specific region. This paper presents all the steps taken in order to design a solarimetric station intended to be used as part of the National Institute for Space Research's(INPE)Environmental Database System (SONDA)network, from the specification of the devices and sensors that will take part in it to the structural dimensioning necessary in order to accommodate them. This high-quality network mainly collects and stores surface solar radiation data, indispensable for the solar energy study and prospecting, therefore of great importance for the generation of energy of the State of Paraná- Brazil.
