适用范围：This part of IEC 60904 describes procedures used to determine the degree of linearity of anyphotovoltaic device parameter with respect to a test parameter. It is primarily intended for useby calibration laboratories, module manufacturers and system designers.Photovoltaic (PV) module and system performance evaluations, and performance translationsfrom one set of temperature and irradiance conditions to another frequently rely on the use oflinear equations (see IEC 60891 and IEC 61829). This standard lays down the linearityrequirements and test methods to ensure that these linear equations will give satisfactoryresults. Indirectly, these requirements dictate the range of the temperature and irradiancevariables over which the equations can be used.The methods of measurement described in this standard apply to all PV devices and areintended to be carried out on a sample or on a comparable device of identical technology. Theyshould be performed prior to all measurement and correction procedures that require a lineardevice. The methodology used in this standard is similar to that specified in IEC 60891 in whicha linear (straight-line) function is fitted to a set of data points using a least-squares fitcalculation routine. The variation of the data from this function is also calculated, and thedefinition of linearity is expressed as an allowable variation percentage.A device is considered linear when it meets the requirements of 7.3.General procedures for determining the degree of linearity for these and any other performanceparameter are described in Clauses 5 and 6.
