Solar Panel Certifications Explained — IEC, UL & More

Why Certifications Matter

Solar panel certifications verify that a panel has been independently tested for safety, performance, and durability. They are required by building codes, insurance policies, and utility interconnection agreements. Without proper certifications, your installation may not qualify for permits or net metering programmes.

Key IEC Certifications

IEC 61215 — Design Qualification

The most important performance standard. Tests include thermal cycling (200 cycles, −40 to 85°C), humidity-freeze, damp heat (1,000 hours at 85°C/85% RH), UV exposure, mechanical load, and hail impact. All LONGi Hi-MO panels are IEC 61215 certified.

IEC 61730 — Safety Qualification

Tests electrical insulation, fire safety, and mechanical integrity. Ensures the panel is safe for personnel and buildings. Required for CE marking in Europe and most global markets.

IEC 61701 — Salt Mist Corrosion

Critical for coastal installations (Dubai, Abu Dhabi). Tests resistance to salt spray corrosion over extended periods. LONGi Hi-MO panels carry this certification.

IEC 62716 — Ammonia Corrosion

Important for agricultural installations near livestock. Tests resistance to ammonia gas corrosion.

UL Standards

UL 61730 (replacing UL 1703)

North American safety standard equivalent to IEC 61730. Required for installations in the USA and Canada.

Additional Certifications

• IEC 62804 — PID resistance testing
• IEC 60068-2-68 — Sand and dust resistance
• MCS — UK Microgeneration Certification Scheme

LONGi's Certifications

All LONGi Hi-MO panels carry IEC 61215, IEC 61730, IEC 61701 (salt mist), and additional regional certifications as required. This comprehensive certification suite ensures suitability for any installation environment.

Frequently Asked Questions

Which certification is most important?

IEC 61215 (design qualification) and IEC 61730 (safety) are mandatory for any legitimate installation. For coastal areas add IEC 61701 (salt mist).

Do all panels have the same certifications?

No. Budget panels may lack salt mist or PID certifications. Always verify the specific certifications on the datasheet match your installation requirements.

Does DEWA require specific certifications?

Yes. DEWA requires panels to meet IEC 61215 and IEC 61730 at minimum, plus additional requirements for their approved equipment list.
