IEC System of Conformity Assessment Schemes
A special certification for Concentrator PV CPV modules is necessary, because the high concentration of the solar irradiance through lenses or mirrors causes higher stress on the equipment. When testing, the prepared and submitted modules undergo HALTs highly accelerated life tests that are not representative of standard real-world conditions.
Basically, certifications per se do not tell much about the quality of a module. IEC tests at the time of applying for certification.
The certifying authority should conduct the same tests 6646 representative samples after the commercial production has started to confirm the quality on the commercially produced item. It is crucial to use PV modules tested against salt mist corrosion certification in case the modules shall be installed near coasts or used for maritime applications.
Moreover, most certification bodies do not perform regular check ups after the certification has been issued, leaving in theory and praxis many opportunities for bad manufacturers to cut quality corners while on paper holding that certification.
The IEC standard specifies the criteria for the design qualification and type approval of concentrator photovoltaic modules and assemblies suitable for long-term operation in general open-air climates.
Nevertheless, depending on where you want to install your panels, the certifications may still be required as per your national requirements or for example in order to apply for FIT. Solar system installers who do installation in areas with heavy ief should definitely use products with an increased load capacity: This has been included in the IEC ed.
Photovoltaic PV module safety qualificationwhich was later ief as the European standard EN almost similar.
I have check IEC, but did not find the right information. Solar installers that are operating in a highly corrosive atmosphere such as near the sea, the resistance of PV panels against the corrosive effects should be checked.

When I buy a solar panel with IEC certification, does it mean the quality of the solar panel is good? Then only the certification should be confirmed. For photovoltaic systems it suggests total insulation, which requires a special insulation of the PV modules according to Safety Class II on the basis of the following requirements:. Nowadays many solar manufacturers produce according this requirement. An iwc test takes the degradation behavior of amorphous silicon due to temperature and irradiance exposure into account.
Or do I also need IEC ?
Thank you very much. The second 61664 consists of the requirements for testing. Niclas is absolutely correct. This includes all forces of nature:. Its purpose and methods.
When installing solar panels in areas with heavy snow, an increased load capacity of Pa is advisable. Isc am a test engineer in SPV lab.
