Or do I also need IEC ?

Niclas is absolutely correct. 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 isc IEC certification, does it mean the quality of the solar panel is good?

IEC certifications: IEC 61215, IEC 61646 and more explained

When installing solar panels in areas with heavy snow, an increased load capacity of Pa is advisable. I am a test engineer in SPV lab. An additional test takes the degradation behavior of amorphous silicon due to temperature and irradiance exposure into 661646.


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.

Its purpose and methods. 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:.

I have check IEC, but did not find the right information. Basically, certifications per 66146 do not tell much about the quality of a module. When testing, the prepared and submitted modules undergo HALTs highly accelerated life tests that are not representative of standard real-world conditions.

Then only the certification should be confirmed. Photovoltaic PV module safety qualificationwhich was later issued as the European standard EN almost similar. 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.

Nevertheless, depending on where you want to irc your panels, the certifications may still be required as per your national requirements or for example in order to apply for FIT. The second part consists of the requirements for testing.


Solar system installers who do installation in areas with heavy snow should definitely use products with an increased load capacity: Thank you very much. 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.

Nowadays many solar manufacturers produce according this requirement. The certifying authority should conduct the same tests on representative samples after 6646 commercial production has started to confirm the quality on the commercially produced item.

This includes all forces of nature:. This has been included in the IEC ed. IEC tests at the time of applying for certification. It is crucial to use PV modules tested 611646 salt mist corrosion certification in case the modules shall be installed near coasts or used for maritime applications.
