24、Uncontrolled Copy, (c) BSI 5 CRYSTALLINE SILICON TERRESTRIAL PHOTOVOLTAIC (PV) MODULES DESIGN QUALIFICATION AND TYPE APPROVAL 1 Scope and object This International Standard lays down IEC requirements for the design qualification and type approval of terrestrial photovoltaic modules suitable for long
25、-term operation in general open- air climates, as defined in IEC 60721-2-1. It applies only to crystalline silicon modules types. A standard for thin-film modules has been published as IEC 61646. This standard does not apply to modules used with concentrated sunlight. The object of this test sequenc
26、e is to determine the electrical and thermal characteristics of the module and to show, as far as is possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure in climates described in the scope. The actual lifetime expectancy of modules so
27、 qualified will depend on their design, their environment and the conditions under which they are operated. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、boratories. 3 Sampling Eight modules for qualification testing (plus spares as desired) shall be taken at random from a production batch or batches, in accordance with the procedure given in IEC 60410. The modules shall have been manufactured from specified materials and components in accordance wit
35、h the relevant drawings and process sheets and have been subjected to the manufacturers normal inspection, quality control and production acceptance procedures. The modules shall be complete in every detail and shall be accompanied by the manufacturers handling, mounting and connection instructions,
36、 including the maximum permissible system voltage. If the bypass diodes are not accessible in the standard modules, a special sample can be prepared for the bypass diode thermal test (10.18). The bypass diode should be mounted physically as it would be in a standard module, with a thermal sensor pla
37、ced on the diode as required in 10.18.2. This sample does not have to go through the other tests in the sequence depicted in Figure 1. 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 8). 4 Marking Each modu
38、le shall carry the following clear and indelible markings: name, monogram or symbol of manufacturer; type or model number; serial number; polarity of terminals or leads (colour coding is permissible); maximum system voltage for which the module is suitable. The date and place of manufacture shall be
39、 marked on the module or be traceable from the serial number. _ 1 Under consideration.

40、ed to sunlight (either real or simulated) to an irradiation level of 5 kWhm2 to 5,5 kWhm2 while open- circuited. The modules shall be divided into groups and subjected to the qualification test sequences in Figure 1, carried out in the order laid down. Each box refers to the corresponding subclause
41、in this standard. Test procedures and severities, including initial and final measurements where necessary, are detailed in Clause 10. NOTE 1 Where the final measurements for one test serve as the initial measurements for the next test in the sequence, they need not be repeated. In these cases, the
42、initial measurements are omitted from the test. In carrying out the tests, the tester shall strictly observe the manufacturers handling, mounting and connection instructions. Tests given in 10.4, 10.5, 10.6 and 10.7 may be omitted if future IEC 61853 has been or is scheduled to be run on this module
43、 type. Test conditions are summarized in Table 1. NOTE 2? The test levels in Table 1 are the minimum levels required for qualification. If the laboratory and the module manufacturer agree, the tests may be performed with increased severities. 6 Pass criteria A module design shall be judged to have p
44、assed the qualification tests, and therefore to be IEC type approved, if each test sample meets all the following criteria: a) the degradation of maximum output power does not exceed the prescribed limit after each test nor 8 % after each test sequence; b) no sample has exhibited any open circuit du
45、ring the tests; c) there is no visual evidence of a major defect, as defined in Clause 7; d) the insulation test requirements are met after the tests; e) the wet leakage current test requirements are met at the beginning and the end of each sequence and after the damp heat test; f) specific requirem
46、ents of the individual tests are met. If two or more modules do not meet these test criteria, the design shall be deemed not to have met the qualification requirements. Should one module fail any test, another two modules meeting the requirements of Clause 3 shall be subjected to the whole of the re
47、levant test sequence from the beginning. If one or both of these modules also fail, the design shall be deemed not to have met the qualification requirements. If, however, both modules pass the test sequence, the design shall be judged to have met the qualification requirements. 7 Major visual defec
48、ts For the purposes of design qualification and type approval, the following are considered to be major visual defects: a) broken, cracked, or torn external surfaces, including superstrates, substrates, frames and junction boxes; EN 61215:2005 Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 1
