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. Or do I also need IEC ? Niclas is absolutely correct. Its purpose and methods. When testing, the 6146 and submitted modules undergo HALTs highly accelerated life tests that are not representative of standard real-world conditions.
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.
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 account. Solar system installers who do installation in areas with heavy snow should definitely use products with an increased load capacity: 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.
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.
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. Photovoltaic PV module safety qualificationwhich was later issued as the European standard EN almost similar. This has been included in the IEC ed.
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. IEC tests at the time of applying for certification.
Then only the certification should be confirmed. I have check IEC, but did not find the right information.
The 6164 authority should conduct the same tests on representative samples after the commercial production has started to confirm the quality on the commercially produced item.
This includes all forces of nature:.
Photovoltaic Solar Testing Specifications
Basically, certifications per se do not tell much about the quality of a module. Thank you very much. When I buy a solar panel with IEC certification, does it mean the quality of the solar panel is good? 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:.

The second part consists of the requirements for testing. When installing solar panels in areas with kec snow, an increased load capacity of Pa is advisable. Nowadays many solar manufacturers produce according this requirement.
