IEC certification solar
About the International Electro Technial Commission (IEC) certifications
The International Electro technical Commission (IEC) certifications are widely recognized quality standard certifications throughout the solar industry. Following an explanatory overview on the various solar-related IEC certifications
IEC 61215 / EN 61215 IEC 61215 Ed. 2 â€“ Ageing of PV modules
The IEC61215 covers the parameters which are responsible for the ageing of PV modules. This includes all forces of nature:
- Sunlight incl. UV.
- Climate (changing of climate, coldness, warmth, humidity).
- Mechanical load (hail, wind suction, wind pressure, snow parameters which are responsible for the ageing of PV modules).
For the standard IEC 61215 certification, 2400 Pa uniform load applies. However:
When you install solar panels in areas with heavy snow, an increased load capacity of 5400Pa is advisable! This has been included in the IEC 61215 ed. 2.Â Nowadays many solar manufacturers produce according this requirement.
Solar system installers who do installation in areas with heavy snow should definitely use products with an increased load capacity:Â 5400 Pa
IEC61646 â€“ Thin-Film PV Modules
The IEC 61646 certification is for Thin-Film PV modules and is in many aspects identical to the international standard IEC 61215 for crystalline modules.Â An additional test takes the degradation behavior of amorphous silicon due to temperature and irradiance exposure into account.
IEC 61730 / EN 61730 â€“ Safety qualifications
Photovoltaic (PV) module safety qualification, which was later issued as the European standard EN 61730 (almost similar). The EN / IEC 61730 consists of 2 parts: the first part covers all the requirements for construction and states the mandatory design characteristics of the modules. The second part consists of the requirements for testing. Part 2 of the EN IEC 61730 defines three different Application Classes for a module design, specifying the type of use, the related qualification tests and the resulting safety class modifications.
IEC 60364-4-41 â€“ Protection against electric shock
Protection against â€œelectric shockâ€ for low-voltage electrical installations; It describes personnel safety measures for electrical systems. 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:
- High dielectric strength
- Mechanical stability
- Sufficient insulation thickness and distances
IEC 62108 â€“ Concentrator PV modules
A special certification for CCP is necessary, because the high concentration of the solar irradiance through lenses or mirrors causes higher stress on the equipment. The IEC 62108 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. The worldâ€™s first IEC 62108 certificate for this technology was issued in June 2009 to California-based SolFocus.
IEC 61701 â€“ Salt mist resistance testing on PV modules
The IEC 61701 certifications tests the resistance of photovoltaic (PV) modules against salt mist corrosion. 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. Itâ€™s definitely a good idea to us the salt mist corrosion certification in case you are installing PV modules near coasts or maritime applications.
