Introduction

IEC 60904 consists of nine parts, of which 8 are identical with part of GB/T 6495, correspondence see the Preface of this section. IEC 60904-6.1994 is identical with the SJ/T11209-1999 "Photovoltaic devices - Part 6. To the standard solar modules begging". IEC 60904 no Part 4, Part 4 GB/T 6495 is identical with IEC 60891. 1987 established GB/T 6495.4-1996 "temperature and irradiance corrections to measured IV characteristics of crystalline silicon photovoltaic devices."

1 Scope

This section GB/T 6495 provisions to test the parameters to determine the parameters of any photovoltaic device linearity program, mainly for calibration Laboratory component manufacturers and system designers to use. By using a linear equation can be achieved on PV modules and system characteristics evaluation can be achieved from a set temperature, irradiance conditions Calculate the characteristic properties under another set of conditions (see GB/T 6495.4 and GB/T 18210). This section aimed at ensuring linear equations Satisfactory results linearity requirements and test methods. These requirements define a change in the system of linear equations can be applied to temperature and irradiance range. Measurement methods described in this section applies to all photovoltaic devices, and can be extended to the technology under the same or comparable samples The device. They should before all the testing and remediation program required the use of a linear device. The method used in this section and GB/T 6495.4 Similar linear function determined, the linear (straight line) function is calculated using the least squares fitting method to fit a set of data points obtained. From This function changes the data can be calculated, and the linearity deviation percentage change allowed to represent. When the temperature and irradiance range satisfies the following conditions are of concern, before considering a linear characteristic of photovoltaic devices. A typical minimum temperature In the range of 25 ℃ ~ 60 ℃, the minimum irradiance range of 700W · m-2 ~ 1000W · m-2. a) With respect to the change in short-circuit current irradiance curve, the slope of the normalized standard deviation (σS/m) of less than 0.02; b) with respect to the irradiance, logarithmic, an open circuit voltage curve, the slope of the normalized standard deviation (σS/m) of less than 0.05; c) with respect to the temperature change of the open circuit voltage and short circuit current curve, the slope of the normalized standard deviation (σS/m) of less than 0.1; d) at the opposite specific spectral range of wavelengths in response to the voltage variation is less than 5%. Note 1. Many IEC PV standards spectral mismatch correction, spectral response measurement Accordingly, with respect to the spectral irradiance and temperature response of linear bits. Sex is very important. This is some of the new technologies such as photochemical cell is important. Note 2. Because some devices such as the relative spectral response of amorphous silicon solar cells with a voltage variation is large, so determining the linear characteristics at a bias voltage is It is important to select the voltage value is determined by the final terms of usage if the concern is the maximum power condition, you can select Vmax;. If it is for school N, (using) a zero bias voltage is more appropriate. Note 3. Note that some of the relative spectral response of the device is a function of temperature and irradiance change some of these effects, such as a) and c) changes in items as may be Press to consider nonlinear circuit current, while in other can not. D) term, the need to press (short circuit current) Consider nonlinear. These and other performance parameters, determine their linear characteristic common procedure in Chapter 4 ~ Chapter 6.
