Solar Simulator의 시험조건에 따른 태양전지모듈의 전기적 특성 분석

Electrical Properties of Photovoltaic Modules with test condition of Solar Simulator

In this paper, maximum output of three different temperature conditions of the photovoltaic modules have been tested and compared to obtain the optimum conditions for the maximum power operation. Temperatures of the cell and module have been set to $20^{\circ}C$, $25^{\circ}C$ and $30^{circ}C$ under the constant light intensity of 1kW/$m^2$. 125${\times}$125mm 36 single crystal solar cells having 80 [W] each have been serially connected in the module. From the results, maximum output deviation of 4.67% has been obtained under the ceil temperature of $20^{\circ}C$ and module temperature of $30^{\circ}C$ while minimum deviation of 0.41${\sim}$0.92% has been measured under the same temperatures of cell and module. Therefore it has been found that the temperature of both cell and module should be fixed to $25^{\circ}C$ to obtain stable data unless the temperature coefficient should be compensated for the testing sample.
