The Complete Solar Compliance Checklist for Australian Installers (2026)

If you’re installing solar panels in Australia, compliance isn’t optional — it’s the foundation of your business.

The Clean Energy Regulator (CER) has been tightening enforcement. In recent years, installer accreditation reviews have increased significantly, and the penalties for non-compliance are getting steeper. In 2023–24 alone, the CER completed over 800 installer audits and took action against dozens of businesses for documentation failures — not substandard physical work.

This checklist covers everything you need to have in order before, during, and after every solar installation job.

Before the Job

CER Accreditation

✅ Current CEC accreditation (check expiry date — accreditation lapses mid-year for many installers)
✅ Correct endorsement categories for the work being performed (solar PV, battery storage, or both)
✅ Professional indemnity insurance up to date and valid for the installation type
✅ Electrical licence valid in your state/territory (check for any state-specific endorsements required)
✅ Any subcontractors on site also hold valid accreditation for their scope of work

Design Compliance

✅ System design compliant with AS/NZS 5033 (Installation and safety requirements for PV arrays)
✅ Inverter listed on the CEC Approved Inverter List
✅ Panels listed on the CEC Approved Modules List
✅ String sizing calculations documented and signed off
✅ Shading analysis completed (particularly important for systems with string inverters)
✅ Roof structural assessment completed (if required by site conditions or system size)
✅ Maximum system size confirmed against DNSP connection approval

Customer Documentation

✅ Grid connection confirmation received from DNSP (export limiting settings confirmed if required)
✅ Metering order lodged with electricity retailer (if new metering required)
✅ Customer handover pack provided (system manual, warranty documents, monitoring app guide, emergency isolation guide)

STC (Small-scale Technology Certificate) Documentation

✅ System details on STC claim match installed equipment exactly (brand, model, serial numbers, rated output)
✅ Installation date recorded accurately — STCs must be claimed within 12 months of installation
✅ Installer accreditation number present on all documentation
✅ Customer declaration form signed (confirming receipt of handover pack)
✅ Photos stored as evidence (minimum: roof array, switchboard, isolators, inverter label with serial number)
✅ STC paperwork stored securely — minimum 5 years from installation date

Battery Storage Jobs — Additional Requirements

If your job includes a battery energy storage system (BESS), you’re working under a separate and more demanding standard. AS/NZS 5139:2019 has specific requirements that go significantly beyond the solar PV checklist:

AS/NZS 5139 Specific Checks

✅ Battery installed in an approved location (garage, dedicated battery room, outdoor enclosure — not living spaces)
✅ Minimum clearances maintained from ignition sources, switchboards, and gas meters
✅ Ventilation requirements met for the specific battery chemistry (vented vs. sealed systems differ significantly)
✅ Emergency isolation switch installed and clearly labelled per AS/NZS 5139
✅ Hazard signage installed at all required locations (entry points, near the battery, near electrical panels)
✅ Battery management system (BMS) confirmed operational
✅ Customer briefed on emergency shutdown procedure and fire response instructions

See our full guide to AS/NZS 5139 battery storage compliance for the detailed requirements, labelling specifications, and common audit failures specific to battery installations.

State-Specific Considerations

Compliance in Australia isn’t fully uniform — each state and territory has its own electrical licensing requirements, Certificate of Electrical Safety (CES) lodgement processes, and in some cases specific rules around metering and grid connection:

NSW — Fair Trading requires CES lodgement within 3 business days of inspection. The Inspector of Electrical Work must be notified for certain system sizes.
VIC — Energy Safe Victoria has specific requirements around solar design documentation and export limiting. Always check current DNSP requirements.
QLD — Electrical Safety Office requires licensed electrical contractors to complete and issue an ESREQ for new connections and major work.
SA — Consumer and Business Services has specific requirements for Certificate of Compliance (COC) documentation.
WA — EnergySafety WA requirements differ from eastern states; check current requirements for solar installations specifically.

When working across multiple states, always verify the current local requirements — they change, and interstate differences catch out even experienced installers.

Common Audit Failure Points

After reviewing CER audit findings data and speaking with installers who’ve been through the process, the most frequent documentation failures are:

STC forms with errors — wrong serial numbers, incorrect installation date, missing customer signature
Photos that can’t be verified — images in camera rolls without timestamps, or photos that can’t be definitively linked to the specific job
Missing compliance checklists — jobs where no formal pre/during/post checklist was completed and stored
Expired accreditation — installers whose CEC accreditation lapsed and wasn’t renewed before the install date
Battery jobs missing AS/NZS 5139 documentation — the additional battery requirements are often overlooked when photovoltaic compliance is otherwise solid

The best protection against all five is a digital job management platform that enforces checklist completion before job close-off, timestamps every photo, and stores all documentation against the job record permanently.

How to Keep This Checklist Audit-Ready

Paper checklists and photos buried in camera rolls won’t cut it when the CER auditor calls. The key to audit readiness is systematic, job-by-job compliance documentation — not a last-minute scramble.

The practical approach:

Build your checklists into your job management system — ServiceM8 and other platforms allow you to create mandatory job checklists that must be completed before a job can be marked done. This removes the human decision to skip the checklist on a busy day.
Capture photos in the platform, not the camera roll — Any platform that attaches photos directly to the job record with automatic timestamps and GPS is infinitely more defensible than a WhatsApp album.
Review your records quarterly — Don’t wait for an audit notice to find out a checklist was missed. A monthly or quarterly internal review of recent job records will catch gaps while they’re still fixable.
Keep a 5-year retention policy — CER requires records for 5 years minimum. Cloud-based platforms handle retention automatically; paper filing requires active management.

Staying Current as Standards Change

Australian solar compliance standards are not static. The CEC updates its installation guidelines periodically. AS/NZS standards are reviewed on a rolling cycle. DNSP requirements for export limiting and metering continue to evolve as grid penetration of solar increases.

The most reliable way to stay current:

Subscribe to CEC installer communications (free as part of your accreditation)
Follow your state electrical safety regulator for local rule changes
Monitor AEMC and AER publications for grid connection policy changes
Use a job management platform that your installation network uses — when standards change, the platforms update their template forms, which prompts you to review your own checklists

We update this checklist as standards change. The biggest pending update to watch in 2026 is the ongoing review of export management frameworks across all states — particularly export limiting requirements that may affect system sizing calculations.

The Bottom Line

Compliance isn’t just about avoiding penalties — it’s about building a reputation that generates referrals and repeat business.

The installers who treat compliance as a feature (not a burden) are the ones winning the best commercial contracts, commanding premium prices, and still operating in 10 years. The ones who cut documentation corners eventually face an audit, a complaint, or a warranty dispute with no paper trail to defend themselves.

Frequently Asked Questions

What compliance standards apply to solar installations in Australia in 2026?

The primary standards are AS/NZS 5033 (PV arrays), AS/NZS 3000 (Wiring Rules), and CEC installation guidelines. Battery storage adds AS/NZS 5139:2019. Installers must hold current CEC accreditation and valid state/territory electrical licences.

What documentation does the CER require?

The CER requires a completed STC assignment form signed by the customer, proof of CEC accreditation, Certificate of Electrical Safety (CES), installation photos at key milestones, serial numbers for all components, and documentation confirming installed equipment matches the approved design.

How long do I need to keep solar installation records?

Minimum 5 years from the date of installation. This includes STC documentation, checklists, photos, certificates, and customer sign-off documents. Cloud-based digital job management platforms handle retention automatically.

What are the most common reasons for failing a CER audit?

Incomplete compliance checklists, STC forms with errors or missing customer signatures, photos that can’t be tied to a specific job and date, missing AS/NZS 5139 documentation for battery jobs, and expired accreditation at the time of installation.

Do I need a separate checklist for battery storage?

Yes. AS/NZS 5139 has specific requirements around labelling, ventilation, emergency isolation, and hazard signage that go beyond the standard solar PV checklist. A combined solar + battery job requires both sets of compliance documentation.

FAQ

What compliance documents are required for a solar installation in Australia?

A standard residential solar installation in Australia requires: (1) a Certificate of Compliance for Electrical Work (CCEW in NSW) or equivalent state certificate (CES in VIC, CCEW in QLD), issued within 7 days of completion; (2) STC lodgement with the Clean Energy Regulator (CER) for the applicable zone and system size; (3) geo-tagged installation photos meeting CER requirements for audit purposes; (4) customer STC assignment declaration; and (5) DNSP network notification where required. Battery installs additionally require AS/NZS 5139 documentation.

What does the Clean Energy Regulator audit during a solar inspection?

CER audits assess whether installations comply with the requirements of the Renewable Energy (Electricity) Act 2000 and the Small-scale Renewable Energy Scheme. Auditors check: CEC accreditation currency for the installing electrician, STC lodgement accuracy (system size, location, STC quantity), geo-tagged photo documentation showing panel layout and labelling, inverter and panel model compliance with the approved product list, AS/NZS 5033 adherence for DC wiring, and proper labelling of AC/DC isolators. The most common audit failure points are inaccurate STC calculations and missing or low-quality geo-tagged photos.

What are the AS/NZS standards that solar installers must comply with?

The primary standards for Australian solar installations are: AS/NZS 5033 (Installation and Safety Requirements for PV Arrays — DC wiring, isolators, labelling), AS/NZS 4777.1 and 4777.2 (Grid Connection of Energy Systems — inverter requirements and installation), and for battery storage, AS/NZS 5139 (Electrical Installations — Safety of Battery Systems). Compliance with AS/NZS 3000 Wiring Rules is also required for all AC electrical work. These standards are referenced in CER audit assessments and in state compliance certificates.

How do I prepare for a CER audit as a solar installer?

The best preparation is maintaining a complete job file for every installation. This should include: a copy of the signed customer STC assignment form, CEC accreditation certificate (current), geo-tagged photos of the installation (roof layout, inverter, meter board, labelling), the compliance certificate (CCEW/CES), the DNSP notification (if applicable), the inverter and panel data sheets confirming they’re on the approved product list, and your AS/NZS 5033 site assessment notes. Using a digital job management system like ServiceM8 to capture and store all of this per-job means you can produce the full audit file in minutes if contacted by the CER.

What happens if my solar installation fails a CER audit?

CER audit failures can result in: revocation of STC certificates (meaning you or your customer loses the rebate), requirement to rectify the installation at your cost, suspension or revocation of your CEC accreditation (preventing future STC claims), and referral to state electrical safety regulators. Serious or repeated breaches can result in criminal penalties under the Renewable Energy (Electricity) Act 2000. The most common outcome of a minor first-time audit failure is a rectification notice — but accreditation suspension is a real risk for documentation or installation deficiencies.
