PV systems

The multi-part ÖVE/ÖNORM E 8001 and ÖVE/ÖNORM E 2750 must be applied when planning, constructing and monitoring photovoltaic systems. ÖVE/ÖNORM E 2750 contains the main requirements to be met by solar modules, wiring, inverter, operation and maintenance (BDB/5 2008). ÖVE/ÖNORM E 8001 deals with protective measures regarding electric shock, fire-hazard rooms, and initial inspections.

ÖVE/ÖNORM E 8049 must be observed with regard to lightning and surge protection. Other important standards regarding PV modules are:

ÖV EN 61215 for crystalline modules:

This standard specifies the IEC requirements for design qualification and type approval of PV modules with crystalline silicon cells suitable for long-term operation in moderate open-air climates to IEC 60721-2-1. The purpose of the test sequences is to determine the electrical and temperature-related benchmarks and to prove that the module is suitable to withstand the climates described for this application over a prolonged period.

ÖV EN 61646 for thin-film modules:

This standard describes the requirements to be met by photovoltaic thin-film modules. It is intended for amorphous silicon technologies, but may also be applied to other PV thin-film modules.

The IEC61215/IEC61646 test certificate has become generally accepted in recent years as a sign of quality for PV modules. It is now required by most approval agencies for national and international subsidisation. A test certificate always refers to the module design used in the tests.

It may only be transferred to modules of the same design that meet the following criteria:
  • all materials used and module components are identical.
  • with regard to cell connection, the same amount or less cells are protected by a bypass diode.
  • module size and rated capacity do not exceed +10% of the type of module tested.
All PV modules that meet these requirements are combined in a PV module type family. Based on the qualification of a PV module type family, the certificate can be expanded by repeating individual relevant tests if the module design changes (TÜV 2005).


This two-part standard describes the requirements regarding module design and materials and explains the safety tests. One special feature of EN 61730 is that the test samples must already be preconditioned by EN 61215/61646 environmental testing methods prior to the actual safety tests. It therefore makes sense to carry out qualification to EN 61215/61646 and EN 61730 in combination. Test samples that have already successfully passed the EN 61215/61646 tests can be used for the EN 61730 safety test (TÜV 2005/1).

CE marking

EN 61730 forms the possible basis for CE (Communauté Européenne) marking of PV modules. CE marking must be seen as a market approval mark and not as a quality mark. By using the CE mark, the manufacturer only confirms that his product conforms to the relevant EU directives.
