For a standard residential system this is routine, and your retailer or installer handles almost all of it. But the process has the same shape wherever you live, and understanding it helps you ask the right questions, tell a normal timeline from a stalled one, and see why a brand-new system sometimes has to sit switched off for a week or two. This guide walks through that universal process, then points you to the specific guide for your own distributor — because the last ten percent (the portal, the exact export limits, the local quirks) is where they differ.
What a DNSP is, and why its approval is the gate
Australia’s electricity system splits into two roles that are easy to mix up. Your retailer is the company that bills you — AGL, Origin, Energy Locals, whoever you pay each month. Your distributor is the company that owns the physical network: the poles, wires, substations and the meter on your wall. You choose your retailer; you don’t get to choose your distributor, because there is only one set of wires in your street and one company that owns it.
That distributor has to sign off on your solar system before it connects, for a straightforward reason. The grid was built to push power one way — from large power stations out to homes. Rooftop solar reverses that flow, feeding electricity back up the line, and too much of it in one area can push local voltage outside safe limits, affect supply quality for your neighbours, and create hazards for crews working on the network. The connection application is how your distributor confirms your system can export safely before it goes live. It protects the network, and it protects the investment you’ve just made.
Which distributor is yours?
If you’re not sure who your distributor is, the fastest way to find out is your electricity bill — the distributor is usually named under the “Faults and emergencies” or supply section, separate from your retailer’s branding. (Most also have a postcode lookup tool on their website.) Find your state in the table below and match your area to the right distributor. The distributor’s name links to its official website; the last column opens our full Solar Nerds guide to connecting with that network.

The connection process, start to finish
Strip away the distributor-specific detail and almost every residential connection runs through the same six steps.
- Pre-approval application. Before any panels go on the roof, your installer lodges a connection application through your distributor’s online portal. It carries your address and National Meter Identifier (the NMI on your bill), the proposed system size, the inverter model, and how much you intend to export. For most homes it goes in as a “basic” or “expedited” connection, which accepts the distributor’s standard terms.
- Network assessment. The distributor checks whether the local network can take your exports without voltage problems. In areas already dense with solar, this is where an export limit may be applied — or, occasionally, where a larger system is pared back.
- Connection offer. If approved, the distributor issues an offer — variously a connection agreement, a Model Standing Offer, or a Permission to Connect. This is the contract that lets your system connect, and it sets out any conditions, including your export limit. Legally, the system can’t be switched on without it.
- Installation. With approval in hand, your installer fits the system and a licensed electrician commissions it, issuing a Certificate of Electrical Safety (or your state’s equivalent) to confirm the work meets standard.
- Meter changeover. Your old meter usually has to be swapped for a bi-directional “smart” meter that records both the electricity you draw in and the electricity you send out. This step is arranged by your retailer, not your distributor — which is exactly why it tends to be the slow one.
- Permission to switch on. Once the meter is in and the final paperwork is lodged, you get the green light to turn the system on and start earning feed-in credits.
The single most important point in that list: your system has to stay switched off until the meter changeover is done. Turning it on early can spin an old meter backwards or see you billed for the power you export, and it breaches your connection agreement.
What your distributor is actually assessing
When it reviews your application, the distributor is weighing a handful of things: whether the local network has spare “hosting capacity” to absorb more solar, how much your system will lift voltage on your street, whether your inverter is on the approved list and complies with the relevant Australian Standard (AS/NZS 4777), and what export limit to set. That export limit is the part homeowners most often misread — it caps how much you can send to the grid, not how much your system can generate or how much you can use in your own home. In high-solar areas it’s increasingly common for limits to be lower, or “dynamic” (flexing with network conditions), which is worth understanding before you lock in a system size.
How long it takes, and where it stalls
For a standard system on a network with capacity, the distributor’s approval is usually quick — often a few business days, sometimes up to ten. The part that varies most is the meter changeover, because it sits with your retailer and its metering contractor: it can take a few days or stretch to several weeks, and it’s the most common reason a finished system sits dark. Larger systems, three-phase connections, and constrained or high-solar networks all add time and may trigger a more detailed technical assessment. As a rough rule, the whole journey from signed contract to switch-on runs somewhere between two and six weeks for most homes — with the meter the wildcard.
Your job vs your installer's job
The reassuring part is that your installer or retailer acts as your agent through all of this. They lodge the application, deal with the distributor, and coordinate the meter request; you never touch the portal yourself. What’s worth doing on your side is small but useful: keep a recent bill handy so your NMI and account details go in correctly, make sure you understand your approved export limit before you sign, don’t switch the system on until you’re told it’s cleared, and if the timeline drifts well past what your installer quoted, chase it — a “lost” application or meter request is a known weak point, and a polite nudge often shakes it loose.
