IEC Standard – Home

This includes all forces of nature:. Eic installing solar panels in areas with heavy snow, an increased load capacity of Pa is advisable. This has been included in the IEC ed.

Nowadays many solar manufacturers produce according this requirement.

IEC certifications: IEC 61215, IEC 61646 and more explained

Solar system installers who do installation in areas with heavy snow should definitely use products with an increased load capacity: An additional test takes the degradation behavior of amorphous silicon due to temperature and irradiance exposure into account. Photovoltaic PV module safety qualificationwhich was later issued as the European standard EN almost similar.


The second part consists of the requirements for testing. For photovoltaic systems it suggests total insulation, which requires a special insulation of the PV modules according 66146 Safety Class II on the basis of the following requirements:. 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.

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. 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. 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.

When I buy a solar panel with IEC certification, does it mean the quality of the solar panel is good? Or do I also need IEC ?

Basically, certifications per se do not tell much about the quality of a module. IEC tests at the time of applying for certification. When testing, the prepared and 611646 modules undergo HALTs highly accelerated life tests that are not representative of standard real-world conditions.


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. 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.

I am a test engineer in SPV lab. Its purpose and methods. I have check IEC, but did not find the right information. Thank you very much. Niclas is absolutely correct.

The certifying authority should conduct the same tests on representative samples after the commercial production has started to confirm the quality on the commercially produced item. Then only the certification should be confirmed.
