Getting Solar Approved Twice: Why Distributor Approval and Electrical Compliance Both Matter

Why does a solar system in Sydney need two separate approvals? Because two different rulebooks apply to it. Your distributor, Ausgrid or Endeavour Energy, must approve the system's connection to its network in writing before it is connected, and the installation itself must be certified as electrically compliant once the work is done. One approval covers the grid, the other covers your wiring, and a system with only one of them cannot legally be switched on.

⚡ Quick Answers: the two solar approvals

• What is the first approval? Network connection approval. The distributor must approve your inverter and protection equipment in writing before the system is connected.
• What is the second? Electrical compliance. Your installer certifies the work with a Certificate of Compliance for Electrical Work (CCEW) covering the installation itself.
• Who arranges them? Your installer or electrician runs both processes, but the system owner is responsible for the system complying overall.
• What does the network want to see? A single line diagram, details of the protection equipment, the inverter's certification number, and a declaration if a battery is included.
• Does system size change things? Yes. Single phase systems over 5kW in urban areas need distributor approval with extra supporting detail, including voltage rise calculations.
• Can I switch on before the meter is sorted? No. A compliant metering installation must be in place before the system is energised.

1. Approval one: the network says yes

Grid connected solar exports power into a shared network, so the distributor gets a say before anything is connected. Under clause 8.6.4 of the Service and Installation Rules of NSW, the inverter and protection equipment must be approved in writing by the distributor before connection, based on an application that includes a single line diagram of the AC side, a full description of the protection equipment and the inverter's Certificate of Suitability number.

Ausgrid and Endeavour Energy run this process differently, with their own portals, timeframes and export rules. We compare them in solar approval differences between Ausgrid and Endeavour, and you can check your network area in seconds with our postcode checker if you are not sure which one covers your home.

2. Bigger systems carry more paperwork

Size thresholds matter. A single phase system rated over 5kW in urban areas, or over 3kW in non urban areas, needs additional information submitted before connection, including voltage rise calculations across the service, the consumer mains and the wiring between switchboard and inverter.

This is also where export limits enter the picture. An export limited or zero export setup can be proposed to speed up approval where the local network is congested, which we explain in why networks cap solar exports.

3. Approval two: the installation is certified compliant

Network approval says the grid can accept your system. It says nothing about whether the wiring on your roof and in your switchboard was done properly. That is the job of the electrical compliance side: the installation must meet the Wiring Rules and the solar standards, and the installer certifies this with a CCEW once the work is complete.

For the rebate side, the federal small scale certificate scheme also requires the system to be installed by an accredited installer working to the CEC guidelines. Our post on what a compliant CEC installation looks like walks through what that accreditation actually requires on the roof.

4. The meter, the switch on and the paperwork trail

Before the system is energised, a compliant metering installation must be in place, which for most Sydney homes means a smart meter upgrade arranged through your retailer. The application details, the approval, the CCEW and the commissioning tests together form the paper trail that proves the system was connected legally.

A good installer treats the final checks seriously rather than as a formality. Our rooftop solar safety checklist covers what gets tested before switch on.

5. What goes wrong when one approval is skipped

Both failure modes show up in the real world. A system installed before network approval can be refused connection, forced onto a tighter export limit than expected, or left waiting while paperwork catches up. A system connected without proper compliance certification is a defect waiting to be found, and it can void the payments and protections the owner assumed they had.

Either way the owner pays twice: once for the install and again to unwind the shortcut. Getting both approvals in the right order costs nothing extra.

Where a Level 2 electrician fits

Solar often exposes the limits of an existing connection. If the application triggers consumer mains issues, a switchboard that cannot take the new circuits, or a case for three phase, that work sits with an accredited Level 2 electrician. We handle consumer mains installation, switchboard upgrades and power supply upgrades so the connection behind the solar is as sound as the panels on top.

How High Demand Electrical helps

We sit on both sides of the fence: licensed electricians for the compliance side and Level 2 ASPs for the network side. That means we can review a solar quote before you sign it, flag whether your connection needs work first, manage the distributor application and make sure the metering and certification land in the right order.

If a solar company has left you stuck between the network and the installer, we can usually identify which approval is missing within one site visit.

Solar approval FAQs (Sydney)

My installer says approval is included. What should I check?

Ask for the distributor's written approval before installation day and the CCEW after commissioning. A professional outfit produces both without hesitation.

How long does network approval take?

Small standard systems are often approved quickly, while larger or export limited systems take longer because more assessment is involved. Timing varies between Ausgrid and Endeavour Energy, so build it into the project rather than booking the install first.

Do battery systems need the same approvals?

Yes, and the battery must be declared in the application and shown on the single line diagram. See our guide to solar battery storage compliance in NSW.

Does the approval transfer when I sell the house?

The approved system stays with the property, which is why the paperwork matters. Keep the approval, the CCEW and the commissioning records with your building documents for the next owner.

Planning solar? Check the connection first
