EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60904-10 test. This section of IEC EN 60904 describes the procedures used to determine the degree of linearity of any photovoltaic device parameter relative to a test parameter. It is primarily intended for use by calibration laboratories, module manufacturers and system designers.
Photovoltaic (PV) module and system performance evaluations and performance translations from a range of temperature and irradiation conditions to another often rely on the use of linear equations. This standard lays down the linearity requirements and test methods to ensure that these linear equations give satisfactory results. Indirectly, these requirements determine the range of temperature and irradiance variables in which the equations can be used.
The measurement methods described in this standard are applicable to all PV devices and are intended to be performed on a sample or comparable device with the same technology. It should be done before all measurement and correction operations that require a linear device. The methodology used in this standard is similar to that specified in IEC 60891; where a linear (straight line) function is fitted to a set of data points using a least squares fit calculation routine. The variation of the data obtained from this function is also calculated, and the definition of linearity is expressed as a percentage of change allowed.
