O uso de células fotovoltaicas como fonte de energia está cada vez mais presente nos sistemas embarcados, portanto a análise do funcionamento dessas células é de extrema importância para verificar a autonomia desses sistemas. Nesse âmbito, a exposição das células fotovoltaicas a uma irradiância conhecida e controlada é imprescindível para testá-las. Assim, utilizando-se um sensor de radiação solar e LEDs, em malha fechada, foi desenvolvido um simulador de irradiâncias de baixo custo. Utilizou-se um controlador PI e foram realizados testes com dados reais de irradiância. Com o sistema proposto, chamado de SIMIRSOL, pode-se analisar o funcionamento das células fotovoltaicas, facilitando o seu uso como fonte de energia em sistemas embarcados.

“…The researches of Al-Ahmad et al [10], Linden et al [16], and Tavakoli et al [18] required the complicated systematic control and structure. Additionally, the construction required many LED which meant that many LED drivers were implemented, thus, the complex control scheme and structure was added on.…”

The article describes a large scale of rectangular light source design comprised of six different types of high-power light emitting diodes (LEDs). The new modular based on the LED solar simulator with the greatest size using the symmetrical LED positioning method. The experiment provided the irradiation of the solar simulator in the class AAA over 416 cm 2 . The rectangular LED module illustrated the uniform distribution of the irradiance across the sample plane area. It reached the class A of air mass 1.5 for global spectrum (AM1.5G) (1000 W/m 2 ) covering the 400 nm to 1100 nm wavelength range. The proposed system offered a spectral match of 100%, the temporal instability equivalent to 0.611%, and a non-uniformity of irradiance less than 2%. When the proposed solar simulator was tested in solar cell characteristics under standard test conditions, it was found that the short circuit current error between the sample solar cell under our solar simulator and the standard solar simulator was less than 0.538%. This proposed design is, therefore, an interesting design that can be applied easily and economically further for large scale solar simulators with its modular system.

“…Generally, four types of lamps are used in a solar simulator: xenon arc lamps, metal halide arc lamps, light-emitting diodes (LEDs), and quartz tungsten halogen lamps. In the literature, examples can be found of solar simulators employing tungsten halogen [1,2], argon arc [3], metal halide [4,5], xenon arc [6,7], and LED lamps [8,9] or several light sources [10,11].…”

This work presents an adjustable large-scale solar simulator based on metal halide lamps. The design procedure is described with regards to the construction and spatial arrangement of the lamps and the designed optical system. Rotation and translation of the lamp array allow setting the direction and the intensity of the luminous flux on the horizontal plane. To validate the built model, irradiance nonuniformity and temporal instability tests were carried out assigning Class A, B, or C for each test, according to the International Electrotechnical Commission (IEC) standards requirements. The simulator meets the Class C standards on a 200 × 90 cm test plane, Class B on 170 × 80 cm, and Class A on 80 × 40 cm. The temporal instability returns Class A results for all the measured points. Lastly, a PV panel is characterized by tracing the I–V curve under simulated radiation, under outdoor natural sunlight, and with a numerical method. The results show a good approximation.
