6 FAQs about [Acceptance criteria for photovoltaic support thickness]

What standards are included in a photovoltaic system?

In addition to referencing international electro-technical photovoltaic standards such as IEC 61215, IEC 61646 and IEC 61730, typical standards from the building sector are also included, such as: EN 13501 (Safety in case of fire); EN 13022 (Safety and accessibility in use); EN 12758 (Protec-tion against noise).

What are the requirements for building integrated photovoltaic (BIPV) modules?

Also, modules for Building Integrated Photovoltaic (BIPV) applications should comply with relevant building code standards. Electrical performance and safety are outside of the scope of this standard and can be referred to in the relevant IEC, UL, IEEE and region specific standards. BS EN 12020-2 Aluminium and aluminium alloys.

What is the IEA photovoltaic power systems programme (PVPS)?

The IEA Photovoltaic Power Systems Programme (PVPS) is one of the technological collaboration programmes (TCP’s) on research and development within the International Energy Agency (IEA).

Do I need a building code standard for a photovoltaic module?

Consequently, exceptions or other standards may need to be specified. For example, sections on frames would not apply to frameless mod- ules. Also, modules for Building Integrated Photovoltaic (BIPV) applications should comply with relevant building code standards.

What does IEC 61215 mean for crystalline photovoltaic modules?

To summarise, if a crystalline photovoltaic module has been certified according to IEC 61215, this standard represents a quality characteristic with regard to the module's long-term mechanical stability for non-BIPV applications, i.e. ground-based or rooftop BAPV, and compliance with electrical requirements.

What are the safety standards for PV modules?

The standard defines the basic safety test requirements and additional tests that are a function of the PV module end-use applications. Test categories include general inspection, electrical shock hazard, fire hazard, mechanical stress, and environmental stress. Status: Currently valid standard, but due for regular ISO review.
