What Happens When You Install Solar?

From Your First Quote to Switch-On

‍

Installing solar isn’t just placing panels on your roof. Long before anyone arrives with a ladder, your electricity habits, roof structure, switchboard, and local network rules come into play. Once the panels are up, the system is tested, documented, linked to monitoring, and sometimes officially approved before it can send power back to the grid.

‍

By understanding each stage, you can confidently compare installers, prepare for installation day, and spot whether the work meets a high standard. Here’s what you can expect when installing solar in Australia, from that first quote request to the exciting moment your system produces its very first kilowatt-hour.

‍

Stage 1: The Initial Solar Enquiry

‍

It all starts with a chat about your home, your energy habits and what’s inspiring you to go solar. You may be asked to provide:

‍

• A recent electricity bill
• Your property address
• Details about when your household uses the most electricity
• Information about existing solar, batteries or electrical equipment
• Whether you plan to add a battery, electric vehicle or major appliance
• Photos of your roof, meter box or switchboard

‍

Your electricity bill gives the installer insight into your energy use: how much power you buy, your tariff, whether you have three-phase power, and how your usage changes throughout the day. This information is crucial because the largest solar system that fits on your roof is not always the best choice. The right design considers how much electricity you use, when you use it, and whether your energy needs might change in the future.

‍

Stage 2: Assessing Your Property

‍

Before suggesting a system, the installer will explore whether your home is a good fit for solar and identify any factors that might influence the installation process. This assessment might involve satellite imagery, photos, electrical details, and if needed, a visit to your property for a closer look. The installer should consider:

‍

• The size, pitch, orientation and condition of the roof
• Shading from trees, neighbouring buildings, antennas or roof structures
• The roof material and available fixing points
• Possible panel locations
• Inverter placement
• Cable routes between the roof, inverter and switchboard
• Switchboard condition and available space
• Whether the property has single-phase or three-phase power
• Local electricity network export limits
• Safe access for the installation team

‍

If your roof needs repairs, your switchboard is outdated, or extra electrical work is required, it’s best to identify these issues well before installation day.

‍

Stage 3: Designing the Solar System

‍

After your property and energy needs are reviewed, the next step is to craft a solar system tailored just for you. This means deciding how many panels you need, where they’ll go, what size inverter to use, which brands to trust, and how everything will connect to your home’s power. A thoughtful design balances your roof space, energy goals, budget, and future plans.

‍

For instance, if you’re planning to buy an electric vehicle, your solar design might differ from a home with low daytime energy use. If you’re thinking about adding a battery in the future, choosing compatible equipment now can make that upgrade smoother later.

‍

At Stag Electrical, systems are designed by qualified electricians rather than solely by a sales team. This helps ensure the proposed layout is practical to install and accounts for electrical safety, network compliance and long-term performance. The company has completed more than 10,000 solar and battery installations since being established in 2007.

‍

Stage 4: Receiving and Comparing the Quote

‍

A quality solar quote should clearly state what you’re getting, not just list a system size and lump sum price.

Look for details including:

• The panel brand, model, quantity and individual wattage
• The inverter brand, model and capacity
• The total system size
• The proposed panel layout
• Expected annual electricity generation
• Assumptions used to estimate savings
• Product and workmanship warranties
• Small-scale technology certificate discounts
• Grid connection or approval requirements
• Monitoring equipment and app access
• Any likely switchboard or electrical upgrades
• Additional charges that may apply

‍

Make sure the quote names the exact equipment models. Vague terms like “Tier 1 panels” or “premium inverter” do not specify what products you’ll actually receive. Remember, projected savings are just estimates, not promises. Your real results will depend on things like weather, shading, electricity rates, system performance and how much solar power you use at home.

‍

Stage 5: Accepting the Quote and Completing the Paperwork

‍

After you accept a quote, some paperwork stands between you and your new solar system. Depending on the location and system, this may include:

• A formal installation agreement
• Permission to apply Small-scale Technology Certificates to the price
• Electricity network connection or export approval
• Finance documentation, if applicable
• Rebate or incentive applications
• Confirmation of equipment and panel layout
• Scheduling the installation date

‍

Your installer usually handles the technical network application, but approval times vary by electricity distributor. After installation, your retailer may need to organise a meter update. If there are any changes to the original design, products or price, be sure to discuss and approve them before installation starts.

‍

Stage 6: Preparing for Installation Day

‍

For most homes, solar installation takes one day. Larger systems, tricky roofs, batteries, or switchboard upgrades may require extra time. Before the installers arrive, you may be asked to:

‍

• Ensure access to the driveway, roof, switchboard and inverter location
• Move vehicles away from the work area
• Unlock gates or meter boxes
• Keep pets and children clear of installation areas
• Confirm access to your home internet for monitoring setup
• Prepare for a temporary electricity interruption

‍

Weather plays a big role in installation. If the roof is wet, very hot, or unsafe, installers may need to reschedule to keep everyone and your property safe.

‍

What Happens on the Roof on Installation Day?

On installation day, the team begins by double-checking your system design and inspecting the roof, switchboard, and equipment locations. Before installing panels, the crew sets up safe roof access and safety gear. Depending on your property, they may use ladders, roof anchors, edge protection, or other fall-prevention tools. The roof work generally involves several steps.

‍

Roof Measurements and Final Layout

Installers double-check measurements, panel spacing, and watch for roof obstacles. Even with a detailed plan, close inspection can reveal small tweaks. Any significant variation from the approved design should be explained before work continues.

‍

Installing Mounting Points

Solar panels do not sit directly on your roof. Sturdy mounting brackets are fixed to the roof structure, supporting aluminium rails that hold each panel. For tiled roofs, installers lift tiles to secure brackets to the rafters underneath. Afterwards, they return the tiles and repair or replace any damaged ones. Installers use specialised mounting feet and weatherproof fixings. Every opening is sealed tightly to keep water out.

‍

Installing Rails and Cabling

Aluminium rails are attached to the mounting points and lined up perfectly, ensuring your panels will sit securely and straight. Next, electrical cables run between the panels and inverter. They are supported, shielded from sharp edges, and kept off the roof to avoid heat, water, or movement damage. Neat workmanship matters beyond looks. Loose cables, poorly sealed openings, or misplaced conduits can affect your system’s safety and lifespan.

‍

Mounting the Solar Panels

Panels are lifted onto the roof, placed on the rails, and fastened with approved clamps. The installer then connects them into electrical strings as planned. The panels should sit straight, remain within permitted roof-edge clearances and be secured according to the mounting manufacturer’s instructions.

‍

What Happens Inside and Around the Home?

As some team members tackle the rooftop, others keep busy below, wiring up the inverter, meter box and switchboard to bring the system to life.

‍

Installing the Inverter

The inverter converts the direct current electricity generated by the panels into alternating current electricity that can be used in the home. Choose a spot for the inverter that stays cool and sheltered with plenty of space. Make sure it is easy to reach for quick checks, maintenance, or if you need to shut it down quickly.

Connecting the Switchboard

‍

The solar system is connected to the home’s switchboard through the required circuit protection and isolation equipment. Expect a short power pause during this work. Power down computers and delicate devices ahead of time to be safe. If your switchboard is outdated, extra work might be needed. This could mean swapping old safety gear, making more room, or upgrading the whole board. Ideally, know about these needs before installation day.

‍

Labels, Isolators and Safety Equipment

The system must include the required safety switches, warning labels and shutdown information. These help electricians, emergency services and homeowners identify the system and isolate it safely when necessary.

‍

Stage 7: Testing and Commissioning

Installing the equipment is only part of the job. Before the system is handed over, the electrician needs to test and commission it.

This generally includes checking:

• Panel and string voltage
• Electrical polarity
• Insulation resistance
• Earthing and electrical protection
• Inverter operation
• Safety switches and isolators
• System communication
• Monitoring connectivity
• Compliance with the approved design
• Whether the system is generating correctly

‍

The installer will also carefully inspect the roof, mounting, cabling, inverter, and switchboard to ensure everything looks right. Stag Electrical’s published Quality and Standards outline a process covering system design, approvals, installation, verification, compliance sign-off, handover and ongoing support. Pre-installation and post-installation photographs are also included within its Platinum Warranty documentation.

‍

Stage 8: System Handover

Before the team packs up, make sure you get a walkthrough of how your new solar system works. A proper handover should explain:

• How to identify whether the system is operating
• How to shut it down safely if required
• How to access the inverter or monitoring app
• What normal generation looks like
• Who to contact if the system reports a fault
• What documentation and warranties apply
• Whether any meter or retailer work remains outstanding

‍

You should receive relevant compliance documentation, warranty information, equipment manuals and electrical safety certification. Do not overlook the monitoring setup. Solar systems can be silent when something is wrong, and without monitoring, you might not notice a problem until your bill jumps. Double-check that the app is running and showing live energy data before you call the handover finished.

‍

Stage 9: Meter Changes and Permission to Export

‍

The panels may be installed and operating before all administrative steps are finalised. Your electricity meter may need to be reconfigured or replaced with a compatible smart meter. Your retailer and network distributor may also need to confirm permission for the system to export surplus electricity to the grid.

‍

Until this is complete, export may be disabled or limited. The solar system may still supply electricity to the home, but the exact arrangement depends on the system, distributor, and local approval conditions. Processing times for metering and network steps can differ, so find out who handles each part and how you will be notified when your system can start exporting.

‍

Stage 10: Your First Days With Solar

‍

Once the system is operational, electricity generated by the panels is used by the home first. Any surplus can be sent to a battery, if installed, or exported to the grid where permitted. If the panels are not producing enough at a moment, the home automatically draws the balance from the grid. You should not need to switch manually between solar and grid electricity.

‍

The first weeks are a great chance to discover your home’s energy habits. The monitoring app reveals when your panels work hardest and, depending on your setup, how much power you use or send out. Try shifting flexible chores like running the dishwasher, washing machine or pool pump into sunny hours. This helps you use more of your own solar power directly.

‍

What Should Happen After Installation?

Your solar journey should not end with the installers’ departure. Support should continue long after the panels are up. Aftercare may include:

‍

• Assistance with monitoring or app connectivity
• Support with inverter fault notifications
• Warranty coordination
• Help interpreting unexpected changes in generation
• Guidance on future battery or EV charger additions
• Repairs relating to installation workmanship

‍

Solar systems have both manufacturer warranties and installation-related warranties. These are not necessarily the same. A panel manufacturer may cover a defective panel, while a workmanship warranty covers how the equipment was installed. Wiring, conduits, brackets, clamps, isolators, roof damage, and call-out costs may be treated differently depending on the installer’s terms.

‍

Stag Electrical offers a comprehensive 25-year Platinum Warranty alongside its lifetime workmanship guarantee. Its published coverage includes wiring and conduits, AC and DC isolators, racking and mounting hardware, broken tiles, certain property damage, electrical safety documentation, warranty documents and no call-out fees for eligible warranty repairs. Conditions and exclusions apply, so homeowners should always read the full warranty terms. (Stag Electrical Platinum Warranty)

Questions to Ask Before Installation Day

Before the job begins, confirm:

1. Has the final panel layout been approved?
2. Are the quoted panel and inverter models still available?
3. Is any switchboard work included in the price?
4. Who will complete the installation?
5. How long is the electricity likely to be turned off?
6. Who manages the grid connection and meter request?
7. Will monitoring be fully configured during handover?
8. What documents will be supplied after installation?
9. Who should be contacted if the system reports a fault?
10. Which parts are covered by the product, workmanship and additional installer warranties?

Getting clear answers upfront helps you avoid surprises and extra costs later.

‍

A great solar installation begins long before anyone sets foot on your roof. It starts with understanding how your home uses power, checking the property and designing a system that truly fits your needs. On installation day, you will see panels appear on your roof, but the real magic happens behind the scenes. Secure mounting, safe cabling, smart inverter placement, careful switchboard work, thorough testing and working monitoring all shape how well your system runs.

‍

The last step is more than just flipping the inverter switch. It is about making sure you understand your system, have all the right paperwork and know who to call if anything needs attention. Your solar system could be part of your home for decades. The care taken in designing, installing, testing and supporting it matters just as much as the brand names on your quote.

Frequently Asked Questions

‍

How Long Does It Take to Install Solar Panels?

Most standard residential solar systems can be installed within one day. Larger systems, complicated roofs, switchboard upgrades, or battery installations may take longer. Installation may be postponed if rain, strong winds, or extreme heat make roof work unsafe.

What Happens Before Solar Installation Day?

Before installation, the installer should assess your electricity use, roof, switchboard, and local network requirements. The system is then designed, equipment confirmed, and any necessary grid connection, rebate, or Small-scale Technology Certificate paperwork completed.

Do I Need to Be Home During the Installation?

An adult usually needs to be present when installers arrive to confirm access, equipment locations, and final details. You may not need to stay home all day, but someone should be available for the system handover and monitoring setup.

Will My Electricity Be Turned Off During Installation?

Yes. Your electricity will generally need to be switched off temporarily while the solar system is connected to the switchboard. The installer will inform you when this will happen so you can safely shut down computers and sensitive equipment.

What Actually Happens on the Roof?

Installers locate the roof structure, secure mounting brackets, and attach aluminium rails. The panels are positioned on the rails, clamped securely, and connected into electrical strings. Cabling is routed from the roof to the inverter while penetrations are sealed and tiles checked for damage.

What Happens if a Roof Tile Is Broken?

Tiles can occasionally crack when lifted to install mounting brackets. A reputable installer should replace or properly repair tiles damaged during installation. Stag Electrical’s 25-year Platinum Warranty covers broken tiles under its applicable terms and conditions.

Will My Solar Work Immediately After Installation?

The system may begin supplying solar electricity to your home once installed, tested, and commissioned. However, exporting excess electricity to the grid may depend on network approval and whether your electricity meter needs reconfiguring or replacement.

Possibly. Many homes require a compatible smart meter before excess solar electricity can be measured and exported to the grid. Your electricity retailer usually coordinates the meter change, though the exact process and timeframe vary between providers.

How Do I Know if My Solar System Is Working?

Your installer should connect the inverter to a monitoring app and show you how to use it before leaving. The app lets you check generation, identify faults, and, depending on the equipment, view household consumption and grid exports.

What Paperwork Should I Receive After Installation?

You should receive electrical safety or compliance documentation, product warranties, workmanship warranty information, equipment manuals, and shutdown instructions. You should also get confirmation of the installed equipment and any documents relevant to grid connection or rebates.
