Testing Services

In the renewable energies sector, and more specifically the photovoltaic field, quality is directly related to performance.
For this reason, it is crucial that specific tests are available for these units. Through carrying out the tests stipulated in different international standards, the manufacturer can ensure that the photovoltaic module under testing complies with all requirements with regard to energy efficiency, mechanical robustness, thermal shock, safety and conformance.
AT4 wireless laboratories are equipped to test the following range of standards:

• IEC 61215 - Crystalline silicon terrestrial photovoltaic (PV) modules - Design qualification and type approval
• IEC 61646 - Thin-film terrestrial photovoltaic (PV) modules - Design qualification and type approval
• IEC 62108 - Concentrator photovoltaic (CPV) modules and assemblies - Design qualification and type approval
• IEC 61730-1- Photovoltaic (PV) module safety qualification - Requirements for construction
• IEC 61730-2 - Photovoltaic (PV) module safety qualification - Requirements for testing.
• IEC 61701 - Salt mist corrosion testing of photovoltaic (PV) modules
• IEC 60904-1 - Photovoltaic devices - Measurement of photovoltaic current-voltage characteristics
• IEC 61345 - UV test for photovoltaic (PV) modules
• IEC 61829 - Crystalline silicon photovoltaic (PV) array - On-site measurement of IV characteristics
• IEC 62124 - Photovoltaic stand-alone systems

Product Certification Marks

AT4 wireless helps to get the top private marks required by the market such as TÜV Nord, SGS and ETL.
AT4 wireless together with its partners offers product certification and production inspection according to the following photovoltaic modules standards IEC 61215, IEC 61730, IEC 61646 and IEC 62108.

Photovoltaic Systems Commissioning Test & Supervision

To guarantee the quality of a photovoltaic facility must be the aim for all agents involved in the photovoltaic energy generation process (manufacturers, developers, financial companies, installer, etc).
To maintain some quality reference as well as a periodic control help to guarantee that actual final production is the same as the one estimated at the design phase of the photovoltaic farm. This is only possible if a detailed analyses of all different components included in a photovoltaic system (invertors, trackers, strings, modules, etc) is performed and a final report of the complete facility is issued.

AT4 wireless provides the following services to allow our customers reaching their main goal, the maximum benefit from their facility for a long term period..

• Control and quality product sampling
• Inspection and verification of photovoltaic facilities:
  • First inspection
  • Periodic inspections
