26、nternational Standard series establishes IEC requirements for evaluating PV module performance based on power (watts), energy (watt-hours) and performance ratio (PR). It is written to be applicable to all PV technologies including non-linear devices, but the methodology does not take into account tr

27、ansient behaviour such as light induced changes and/or thermal annealing. Included in the IEC 61853 series of standards are: a guide to mapping module performance over a wide range of temperature and irradiance conditions; methods for characterising spectral and angular effects; definition of refere

28、nce climatic profiles (temperature and irradiance); methods for evaluating instantaneous power and energy results; and a method for stating these results in the form of a numerical rating.

29、radiance and temperature performance measurements and power rating 1 Scope and object This part of IEC 61853 describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures. IEC 61853-2 describes test procedures for measuring

30、the performance effect of angle of incidence; the estimation of module temperature from irradiance, ambient temperature and wind speed; and impact of spectral response on energy production. IEC 61853-3 describes the calculations of PV module energy (watt-hours) ratings. IEC 61853-4 describes the sta

31、ndard time periods and weather conditions that can be utilized for calculating standardized energy ratings. The object of this part of IEC 61853 is to define a testing and rating system, which provides the PV module power (watts) at maximum power operation for a set of defined conditions. A second p

32、urpose is to provide a full set of characterization parameters for the module under various values of irradiance and temperature. This set of measurements is required in order to perform the module energy rating described in IEC 61853-3. 2 Normative references The following referenced documents are

38、es shall be selected at random from a production batch or batches in accordance with the procedure given in IEC 60410. The modules shall be pre-conditioned in accordance with Clause 5 to ensure the stability of the power values. The modules shall have been manufactured from specified materials and c

39、omponents in accordance with the relevant drawings and process sheets and shall have been subjected to the manufactures normal inspection, quality control and production acceptance procedures. The modules shall be complete in every detail and shall be accompanied by the manufacturers handling and fi

40、nal assembly instructions regarding the recommended installation of any diodes, frames, brackets, etc. When the modules to be tested are prototypes of a new design and not from production, this fact shall be noted in the test report (see Clause 6). 4 Marking Each module shall carry the following cle

41、ar and indelible markings: name, monogram or symbol of the manufacturer; type or model number; serial number; polarity of terminals or leads (colour coding is permissible); nominal and minimum values of maximum output power at STC after preconditioning, as specified by the manufacturer for the produ

42、ct type (see Clause 5). The date and place of manufacture shall be marked on the module or be traceable from the serial number. For future production the power ratings for NOCT, LIC, HTC and LTC determined by this standard as defined in Clause 7 and Table 1 and determined via the procedure in 9.2 sh

43、all be marked on a label, or be stated in the manufacturers literature provided with each module of this type. 5 Testing and pass criteria The modules shall be subjected to the procedure for irradiance and temperature performance measurements defined in Clause 8. In carrying out the tests, the manuf

44、acturers handling, mounting and connection instructions shall be observed. Special considerations: Preconditioning - Before beginning the measurements, the device under test shall be stabilized by light soaking, as specified in IEC 61215 (Clause 5) or IEC 61646 (10.19). The values of STC power measu

45、red after preconditioning shall fall within the power range specified by the manufacturer of this product. BS EN 61853-1:2011 8 61853-1 IEC:2011 NOTE The pass/fail criteria must consider the laboratory uncertainty of the measurement. As an example, if the laboratory extended uncertainty of the STC m

46、easurement is 5 %, then a nominal nameplate rated power greater than 95 % of the laboratory measured power would meet the pass criteria. After generating the matrix of parameters in Section 8 the modules should be remeasured at STC to verify that the performance is stable. 6 Report Following complet

47、ion of the procedure, a certified report of the performance tests, with measured power characteristics shall be prepared by the test agency in accordance with the procedures of ISO/IEC 17025. Each certificate or test report shall include at least the following information: a) a title; b) name and ad

48、dress of the test laboratory and location where the calibration or tests were carried out; c) unique identification of the certification or report and of each page; d) name and address of client, where appropriate; e) description and identification of the item calibrated or tested; f) characterizati
