What photo evidence does the CER require for solar battery installations in 2026?

From 1 March 2026, the Clean Energy Regulator (CER) requires clear photographic evidence for every solar battery installation claiming STCs under SRES. Required photos include: (1) the meter box showing a green ES label with UN3480 designation below it, (2) the switchboard showing a MULTIPLE MODE warning label and shutdown procedure label, (3) the battery installation showing required hazard signs (toxic fumes, battery explosion, arc flash), and (4) an installer selfie at the worksite. Photos must be geotagged and timestamped.

What is the ES label requirement for solar battery meter box compliance in Australia?

The ES label (Energy Storage label) must be a green circle affixed to or near the meter box. It must contain the letters 'ES' and have the UN3480 (Lithium Ion Battery) designation text displayed below the ES lettering. This is required under AS/NZS 5139 and CER photo evidence guidelines effective March 2026.

How do I pass a CER solar compliance audit?

To pass a CER solar compliance audit, ensure you have clear photos showing: correct ES and PV labels on the meter box, MULTIPLE MODE warning label and shutdown procedure label on the switchboard, required hazard signs near the battery system, and a clear installer selfie at the worksite. All photos must be geotagged and timestamped at time of installation. SolarLens AI can check your photos instantly before submission.

What Australian standards apply to solar battery installations?

Solar battery installations in Australia must comply with: AS/NZS 5139 (Safety requirements for battery systems for use with power conversion equipment), AS/NZS 5033 (Safety requirements for PV arrays), AS/NZS 4777.1 (Grid connection of energy systems via inverters), and AS 3000 (Wiring rules). Clean Energy Regulator (CER) photo evidence guidelines effective March 2026 also require specific photographic documentation.

Can I use AI to check my solar installation photos for CER compliance?

Yes. SolarLens AI uses Google Gemini AI to automatically analyse solar installation photos and verify them against CER 2026 photo evidence guidelines and AS/NZS standards. It detects ES labels, UN numbers, warning signs, hazard symbols, and produces a PASS/FAIL/WARNING verdict with detailed reasoning in under 30 seconds. Try 5 free checks at solarlensai.com.

Avoid CER STC Rejections: The Ultimate Compliance Photo Checklist

Published: 17 March 2026 SolarLens AI™ Compliance Team

For Australian solar businesses, STC (Small-scale Technology Certificate) payouts are critical for cash flow. However, as the Clean Energy Regulator (CER) moves towards automated AI auditing in 2026, the margin for error is effectively zero. A single missing photo or a blurry label can hold up thousands of dollars for months. Use this master checklist to ensure every site visit is a success.

1. The Meter Box & Entry Point

The ES Label (Energy Storage)

Must be a clear, centered shot showing the green ES circle AND the UN3480 text below it. If it's old/faded, replace it before taking the photo.

Main Switch (PV Supply)

Clearly visible main switch with the "Main Switch (Inverter Supply)" sticker applied correctly.

Warning Solar Array Label

Must be present on the meter box and main switchboard to warn of multiple power sources.

2. The Switchboard (Mandatory Photos)

The CER requires proof that the safety configuration of the property has been updated to reflect the new solar/battery installation.

Multiple Mode Warning Label

Specifically required for installations with battery backup (UPS mode) capability.

Shutdown Procedure

A clear, well-lit photo of the complete shutdown sequence. Text must be 100% legible to the AI vision engine.

Specialist Tech Tip

"Never send compliance photos via WhatsApp or Messenger. These apps strip the GPS and Time metadata (EXIF data) required by the Clean Energy Regulator. Use the SolarLens AI™ mobile app or upload original files directly from your gallery to preserve data integrity."

Don't Leave Money on the Roof

Every site visit costs money. A single revisit to "fix a label" or "re-take a photo" can erase your entire profit margin for that job. By integrating a checklist culture supported by AI verification, you can guarantee a 100% first-time approval rate for your STC claims.
