Buying solar is a big decision, and not knowing what happens between “yes” and “switch-on” is one of the most common worries we hear. The good news is that the installation process follows a clear sequence. This guide walks through each stage, explains who does what, and lists what you can have ready so the day goes smoothly.
The short version
- From first assessment to switch-on, a typical home project has seven stages.
- The physical installation of a standard home system is usually completed in a single day, though larger systems and batteries can take longer.
- The longest waits are usually approvals and the meter change, not the work on your roof.
- Your installer should handle the grid application, the rebate paperwork and the electrical compliance certificate.
Stage 1: The Free Assessment
Everything starts with understanding your home. We look at your roof, including its size, pitch, orientation and any shading from trees or neighbouring buildings. We check your switchboard and meter, and whether you have single-phase or three-phase supply. We also talk about how your household uses electricity, because a family that is home all day uses power differently from a household that is out until evening.
This is also when we discuss goals. Some people want lower bills, others want to be ready for a battery, and some want to reduce their reliance on the grid. The answers shape the system we recommend.
Stage 2: Design and Proposal
Next we design a system for your property and give you a written proposal. A good proposal lists the panels and inverter by brand and model, the system size in kilowatts, the number of panels and where they go on your roof, the warranties, and what is included in the installation. Federal and state discounts are shown as their own lines so you can see what applies. If you are considering a battery now or later, this is the time to design for it. Our guides to solar panels and inverters explain the equipment choices.
Stage 3: Approvals and Paperwork
Before any work starts, several approvals are lined up:
- Network approval. Your electricity distributor needs to approve the connection and any export limits. We lodge this application for you.
- Rebates and certificates. We confirm which programs apply to your property and handle the paperwork. In Victoria, for example, the Solar Homes rebate must be approved before installation. See our guide to the Victorian solar rebate.
- Contracts and scheduling. Once approvals are in place, we agree a date that suits you.
Approval times vary by network and by how busy they are. We keep you updated rather than leaving you wondering where things are up to.
Stage 4: Installation Day
On the day, a licensed installation team arrives with the equipment. A typical home installation runs in roughly this order:
- Site safety setup. The team sets up safe roof access and protection around the work area.
- Mounting. Rails and mounting brackets are fixed to the roof structure and sealed.
- Panels. Panels are fitted to the rails and connected in strings.
- Inverter and wiring. The inverter is mounted, usually near your switchboard, and the DC and AC wiring is completed with the required isolators and labelling.
- Battery (if included). A battery adds extra work, including its location, protection and connection, and can add time.
- Testing. The system is tested before it is handed over.
You will be without power for a short period while the system is connected to your switchboard. We tell you in advance when that is likely to happen.
Stage 5: Compliance and Metering
After installation the electrical work is signed off and a compliance certificate is lodged. Your retailer and network operator may need to fit or reprogram a meter that can measure both the power you use and the power you export. This stage is often the longest wait of the whole project, and in some areas the system cannot be switched on until it is complete. Our guide to the Tasmanian connection process shows what that looks like in practice.
Stage 6: Switch-On and Handover
Once approval and metering are done, the system is commissioned and switched on. We then walk you through the monitoring app, show you how to see production and household use, and give you the documents you will need: warranties, certificates, and the manuals for your equipment. This is a good moment to ask anything you want to know about what the numbers mean.
Stage 7: After the Installation
- Check your retailer plan. Your feed-in tariff comes from your retailer, so compare offers once the system is on.
- Keep your paperwork. Warranty claims and future upgrades are much easier with the original documents.
- Know who to call. If something goes wrong in year three or year seven, you should know whether to call the installer or the manufacturer.
What to Have Ready Before Installation Day
- Clear access to the switchboard, the meter box and the area where the inverter will go.
- Cars and outdoor items moved away from the work area, and pets safely indoors.
- Someone home to give access at the start and sign off at the end.
- A plan for the short power outage, such as charging devices and not scheduling anything that depends on power during that window.
- Your Wi-Fi details handy, so the monitoring app can be set up during handover.
How Long Does Everything Take?
There is no single answer because it depends on the approvals in your area and your equipment. Many customers find that the on-site work takes a day, while the weeks before and after are spent on approvals and metering. We give you a realistic timeline when we know your network and your chosen system, and we tell you if anything changes.
Why Choose a Local Installer?
Sunflare Solar is based in Melton and installs across Victoria, Tasmania, New South Wales and Western Australia. Local knowledge matters because every network and every state has its own approval steps and rebate settings. See our residential solar page, or the location pages for Melton, Geelong and Hobart.
Frequently Asked Questions
How long does a solar installation take?
Most home systems are installed in a single day. Larger systems or ones that include a battery can take longer. Approvals and metering often take longer than the installation itself.
Do I need to be home during installation?
It helps to have someone available for access and the final walkthrough, but you do not need to stay in the room the whole time.
Will my power be off during installation?
Yes, briefly. The power is switched off for a short period while the system is connected to your switchboard.
When does the system switch on?
After testing, compliance sign-off, network approval and any required meter change.
Who applies to the electricity network?
Sunflare Solar lodges the connection application with your distributor on your behalf.
Do I have to apply for rebates myself?
Federal discounts are handled by your installer. Some state programs, such as the Victorian Solar Homes rebate, require you to upload documents, and we guide you through it.
What happens if it rains on installation day?
Roof work may be rescheduled when conditions are unsafe. We will contact you to agree a new date.
Can I add a battery later?
Often yes. Designing for a battery from the start, for example with a hybrid inverter, can make a later upgrade simpler.
