29、pecifies the minimum requirements for the design qualification and type approval of concentrator photovoltaic (CPV) modules and assemblies suitable for long-term operation in general open-air climates as defined in IEC 60721-2-1. The test sequence is partially based on that specified in IEC 61215 fo
30、r the design qualification and type approval of flat-plate terrestrial crystalline silicon PV modules. However, some changes have been made to account for the special features of CPV receivers and modules, particularly with regard to the separation of on-site and in-lab tests, effects of tracking al
31、ignment, high current density, and rapid temperature changes, which have resulted in the formulation of some new test procedures or new requirements. The object of this test standard is to determine the electrical, mechanical, and thermal characteristics of the CPV modules and assemblies and to show
32、, as far as possible within reasonable constraints of cost and time, that the CPV modules and assemblies are capable of withstanding prolonged exposure in climates described in the scope. The actual life of CPV modules and assemblies so qualified will depend on their design, production, environment,
33、 and the conditions under which they are operated. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、 that use concentrated sunlight 3.2 concentrator cell basic photovoltaic device that is used under the illumination of concentrated sunlight 3.3 concentrator optics optical device that performs one or more of the following functions from its input to output: increasing the light intensity, filtering
37、 the spectrum, modifying light intensity distribution, or changing light direction. Typically, it is a lens or a mirror. A primary optics receives unconcentrated sunlight directly from the sun. A secondary optics receives concentrated or modified sunlight from another optical device, such as primary
38、 optics or another secondary optics. 6 BS EN 62108:2008 Copyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Licensee=Boeing Co/5910770001 Not for Resale, 08/14/2008 21:33:37 MDTNo reproduction or networking permitted without license from IHS -,-,- 3.4 c
39、oncentrator receiver group of one or more concentrator cells and secondary optics (if present) that accepts concentrated sunlight and incorporates the means for thermal and electric energy transfer. A receiver could be made of several sub-receivers. The sub-receiver is a physically stand- alone, sma
40、ller portion of the full-size receiver. 3.5 concentrator module group of receivers, optics, and other related components, such as interconnection and mounting, that accepts unconcentrated sunlight. All of the above components are usually prefabricated as one unit, and the focus point is not field ad
41、justable. A module could be made of several sub-modules. The sub-module is a physically stand-alone, smaller portion of the full-size module. 3.6 concentrator assembly group of receivers, optics, and other related components, such as interconnection and mounting, that accepts unconcentrated sunlight
42、. All of the above components would usually be shipped separately and need some field installation, and the focus point is field adjustable. An assembly could be made of several sub-assemblies. The sub-assembly is a physically stand-alone, smaller portion of the full-size assembly. 3.7 representativ

44、CPV Module prefabricated and the focus point is not field adjustable, similar to most Fresnel lens systems. CPV Assembly needs some field installation and the focus point is field adjustable, similar to most reflective systems. 4 Sampling For non-field-adjustable focus-point CPV systems or modules,
45、7 modules and 2 receivers are required to complete all the specified tests, plus one receiver for the bypass/blocking diode thermal test (intrusive or non-intrusive). For details, see Figure 6. For field-adjustable focus- point CPV systems or assemblies, 9 receivers (including secondary optics secti
46、ons, if applicable) and 7 primary optics sections are required to complete all the specified tests, plus one receiver for the bypass/blocking diode thermal test (intrusive or non-intrusive). For details, see Figure 7. In the case that a full-size module or assembly is too large to fit into available
47、 testing equipment, such as environmental chambers, or a full-size module or assembly is too expensive (e.g., for a 20 kW reflective dish concentrator system, 9 receiver samples account for 180 kW of PV cells), a smaller representative sample may be used. However, even if representative samples are
48、used for the other test, a full-size module or assembly should be installed and tested for outdoor exposure. This can be conducted either in the testing lab, or through on-site witness. 7 BS EN 62108:2008 Copyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Licensee=Boeing Co/5910770001 Not for Resale, 08/14/2008
