29、1995 BSI 10-19993 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-term operation in moderate open-air climates, as defined in IEC 721-2-1. It applies only to crystalline sil
30、icon types. Standards for thin-film modules and other environments, such as marine or equator conditions, are under consideration. This standard does not apply to modules used with concentrators. The object of this test sequence is to determine the electrical and thermal characteristics of the modul
31、e 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 qualified will depend on their design, their environment and the conditi
32、ons under which they are operated. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All normative documents are subje
33、ct to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

Amendment No. 1 (1992) 3 Sampling Eight modules for qualification testing (plus spares as desired) shall be taken at random from a production batch or batches, in accordance wit
38、h the procedure given in IEC 410. The modules shall have been manufactured from specified materials and components in accordance with the relevant drawings and process sheets and have been subjected to the manufacturers normal inspection, quality control and production acceptance procedures. The mod
39、ules shall be complete in every detail and shall be accompanied by the manufacturers handling, mounting and connection instructions, including the maximum permissible system voltage. When the modules to be tested are prototypes of a new design and not from production, this fact shall be noted in the
40、 test report (see clause 8). 4 Marking Each module shall carry the following clear and indelible markings: name, monogram or symbol of manufacturer; type or model number; Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 14:06:01 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 61215:1995 4 BSI 10
41、-1999 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 marked on the module or be traceable from the serial number. 5 Testing The modules shall be divided into groups and
42、subjected to the qualification test sequences in Figure 1, carried out in the order laid down. Each box refers to the corresponding subclause in this standard. Test procedures and severities, including initial and final measurements where necessary, are detailed in clause 10. NOTEWhere the final mea
43、surements for one test serve as the initial measurements for the next test in the sequence, they need not be repeated. In these cases, the initial measurements are omitted from the test. In carrying out the tests, the tester shall strictly observe the manufacturers handling, mounting and connection
44、instructions. Test given in 10.4 may be omitted if the temperature coefficients and “ are already known. Test conditions are summarized in Table 1. 6 Pass criteria A module design shall be judged to have passed the qualification tests, and therefore to be IEC type approved, if each test sample meets
45、 all the following criteria: a) the degradation of maximum output power at standard test conditions (STC) does not exceed the prescribed limit after each test nor 8 % after each test sequence; b) no sample has exhibited any open-circuit or ground fault during the tests; c) there is no visual evidenc
46、e of a major defect, as defined in clause 7; d) the insulation test requirements are met after the tests. 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 th
47、e requirements of clause 3 shall be subjected to the whole of the relevant 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 jud
48、ged to have met the qualification requirements. 7 Major visual defects For the purposes of design qualification and type approval, the following are considered to be major visual defects: a) broken, cracked, bent, misaligned or torn external surfaces; b) a crack in a cell whose propagation could rem
49、ove more than 10 % of that cells area from the electrical circuit of the module; c) bubbles or delamination forming a continuous path between any part of the electrical circuit and the edge of the module; d) loss of mechanical integrity, to the extent that the installation and/or operation of the module would be impaired. 8 Report Following type approval, a certified report of the qualification tests, with measured performance characteristics and details of any failures and re-tests, shall be prepare
