Solar Mounting
Certifications Explained
AS/NZS 1170, IEC, UL 2703, TÜV, Eurocode — what each standard covers, which markets require it, and how OmniSol documents compliance for each.
Why Certifications Matter for Solar Mounting
Solar mounting certifications serve two distinct purposes: structural compliance (proving the system can survive the loads at the installation site) and product safety (proving the hardware meets manufacturing quality standards for the market). These are different things, and confusion between them is common.
Structural compliance — AS/NZS 1170, ASCE 7, Eurocode — is calculated per project, not per product. The same roof clamp can be compliant in Adelaide (AS/NZS 1170 Region A) and non-compliant in Cairns (Region C) if the installer uses the wrong fixing spacing. The product itself doesn't hold a structural "certification" — the engineering report for a specific project does.
Product certifications — UL 2703, IEC 62852, TÜV test reports — are held by the manufacturer for a specific product design. These confirm the product was tested under defined conditions and met the standard. OmniSol's team will confirm which certifications are held for each product before your order is placed.
Australia & New Zealand
Structural loading — permanent and imposed loads on structures
Engineering calculations per this standard required for building permit submission in most Australian states.
Wind actions — the primary structural standard for AU solar mounting
Defines wind regions A through D. Region C/D (cyclone) requires site-specific engineering certification.
Snow and ice loads — relevant for elevated or alpine installations
Required for ACT highlands, Alpine NSW/VIC, and elevated South Island (NZ) sites.
Hot-dip galvanized coatings on fabricated ferrous articles
Defines minimum 85 µm zinc coating for exposed structural steel. OmniSol specifies compliance coating as standard.
International (IEC)
Design qualification and type approval for PV modules — mounting interface
Module mounting clamp geometry and clamping force must be compatible with IEC 61215 tested modules. OmniSol clamps are verified against standard module frame dimensions.
MC4 connector requirements — mating, locking, and disconnection under load
Required for all MC4 connectors in IEC markets. OmniSol MC4 connectors are IEC 62852 certified, IP68 rated.
Junction boxes for PV modules — safety, IP rating, flammability
OmniSol PV junction boxes carry IEC 62790 certification with IP68 and UL94-5VA flame class.
Electric cables for photovoltaic systems — H1Z2Z2-K specification
Required for DC cables in EU/IEC markets. OmniSol 1500V DC cable is TUV certified to EN 50618.
Quality management system for manufacturing
OmniSol operates and audits suppliers against ISO 9001:2015 as a baseline qualification requirement.
Europe (EU / Germany)
Basis of structural design — the EU equivalent of ASCE 7
Load calculations for EU solar projects must reference Eurocode 0/1. OmniSol provides Eurocode-based engineering reports.
Wind loads on structures — Eurocode wind action standard
Site-specific wind speed from national annex. OmniSol provides EN 1991-1-4 calculations for all EU projects.
Declaration of Performance for construction products (EU CPR)
Structural mounting components sold into the EU must carry CE marking with a Declaration of Performance referencing Eurocode.
Third-party product testing and certification (Germany)
While not legally mandatory, TÜV test reports are widely expected by German EPCs. Available for key OmniSol products on request.
United States
Mounting systems for PV: structural + electrical bonding/grounding
Not nationally mandated, but required by many AHJs (Authorities Having Jurisdiction). Covers both structural load capacity and electrical grounding continuity.
Minimum design loads for buildings — wind, snow, and seismic
Referenced by IBC. OmniSol provides ZIP-code-specific ASCE 7-22 wind and snow load calculations for all US projects.
Connector systems for use in photovoltaic systems — US standard
US equivalent of IEC 62852 for MC4 connectors. OmniSol MC4 connectors have UL 6703 / IEC 62852 dual certification.
PV junction boxes — US safety standard
UL-listed junction boxes required by some US installers and utilities. OmniSol stocks both IEC 62790 and UL 3730 certified options.
