How to Choose the Best Solar and Battery Installer in Brisbane: 10 Things to Look For

Investing in solar panels or battery storage is a significant decision for any homeowner. With so many solar companies operating across Brisbane and South East Queensland, knowing which installer to trust isn't always straightforward.

Different companies offer different products, system sizes, warranties and prices. While a competitive quote is important, the quality of the installation and the support you receive afterwards can have just as much impact on your long-term investment.

Whether you're installing solar for the first time, adding battery storage to an existing system or upgrading older equipment, choosing the right installer starts with knowing what to look for.

Here are 10 important things to consider before choosing a solar and battery installer in Brisbane.

1. Ask Who Will Actually Install Your Solar and Battery System

One of the most overlooked questions when comparing solar companies is who will physically complete the installation.

Some solar retailers employ their own electricians, while others use subcontracted installation teams. Both models can deliver quality work, but there are important differences in how installations are managed.

With an in-house electrical team, the company has direct oversight of its electricians, workmanship standards, training and installation processes.

This can provide greater consistency across installations and clearer accountability if something requires attention afterwards.

Before accepting a quote, ask:

• Does the company employ its own electricians or use subcontractors?
• Who is responsible for installation quality and safety?
• Are the installers appropriately licensed and accredited?
• Who will handle any workmanship concerns after installation?

At Open Electrical, we don't use subcontracted installation crews. Our solar and battery installations are completed by our own qualified, in-house electricians.

It's part of our Electricians First approach, where quality electrical workmanship remains at the centre of everything we do.

2. Check the Solar Installer's Experience, Accreditations and Reputation

Solar and battery systems are designed to operate for many years, making the experience and reliability of your installer particularly important.

Before choosing a company, consider how long it has been operating, how many installations it has completed and whether it has an established presence in your area.

It's also important to understand the difference between business accreditations and individual installer qualifications.

In Australia, Solar Accreditation Australia (SAA) accredits individual solar and battery installers. You can check an installer's accreditation status through the SAA website.

You should also look for companies approved under the New Energy Tech Consumer Code (NETCC), which sets consumer protection standards covering sales, installation, warranties and support.

Open Electrical has been family-owned and operated since 2013, with more than 5,000+ installations completed across Queensland.

Our credentials include:

• SolarQuotes Platinum Rated Installer
• Sigenergy Gold Rated Installer
• NETCC Approved Seller
• Master Electricians Australia member

These credentials reflect our commitment to professional workmanship, quality equipment and customer service.

3. Don't Choose a Solar Installer Based on Price Alone

When comparing solar and battery quotes, it's tempting to focus on the final price.

However, two systems with similar advertised capacities can vary considerably in product quality, installation requirements, backup capabilities and warranty support.

A lower-priced system may use different equipment, offer fewer features or exclude electrical work included in another quote.

For example, one battery package may include blackout backup equipment, while another may require additional components to provide the same functionality.

Before making a decision, compare the full system rather than the headline price.

Look closely at the solar panel and inverter brands, usable battery capacity, installation inclusions, warranty conditions and ongoing support.

The cheapest solar system is rarely the cheapest long term.

A quality system should deliver reliable performance and be supported by a company you can depend on for years to come.

4. Make Sure Your Solar and Battery System Is Designed for Your Home

Not every household needs the same solar or battery capacity.

The right system depends on how much electricity your household uses, when you use it and what you're hoping to achieve.

A household with high evening electricity consumption may benefit from a different battery configuration than a home where most electricity is consumed during the day.

Your installer should consider:

• Your current electricity bills and daily energy consumption
• Existing solar generation, if applicable
• Roof orientation, available space and shading
• Daytime versus evening electricity usage
• Battery storage requirements
• Future additions such as electric vehicles or pool heating
• Whether blackout backup is a priority

For homeowners who already have solar, adding a battery doesn't necessarily mean replacing the entire system.

An experienced installer should assess your existing equipment and determine which battery options are compatible with your setup.

At Open Electrical, we design solar and battery solutions around each property's electrical requirements, rather than relying on a one-size-fits-all package.

5. Understand What Your Solar Battery Will Actually Do

Battery storage has become an increasingly popular consideration for Queensland homeowners, but not all batteries offer the same features.

A solar battery can store excess solar energy generated during the day for use later, helping reduce the amount of electricity purchased from the grid.

However, battery storage and blackout backup are not automatically the same thing.

Some batteries require additional equipment to supply electricity during a power outage. Depending on the system design, backup may cover selected household circuits or a broader range of appliances.

Before purchasing a battery, ask:

• How much usable energy can the battery store?
• What is its continuous power output?
• Will it provide electricity during a blackout?
• Which appliances or circuits will remain powered?
• Can the battery capacity be expanded later?
• Does the system include an app for monitoring and energy management?

For homeowners across Brisbane and South East Queensland, backup capabilities can be particularly valuable when preparing for storm season.

It's important to discuss these requirements before installation so the system can be designed accordingly.

6. Look Beyond the Product Warranty

Solar panels, inverters and batteries are long-term investments, so warranty coverage should be a major consideration.

But not all warranties cover the same things.

When comparing systems, ask about the manufacturer's product warranty, battery performance warranty and installation workmanship warranty.

You should also understand who handles warranty claims and whether the equipment manufacturer has established Australian technical support.

A warranty may look impressive on paper, but the process for accessing support matters just as much.

At Open Electrical, we work with established solar and battery manufacturers and consider the availability of Australian support when selecting equipment.

Our aim is to provide customers with quality products backed by reliable long-term service.

7. Read Customer Reviews and Look at Previous Installations

Customer reviews are one of the most useful ways to research a solar installation company.

However, don't rely solely on the overall star rating.

Look for detailed feedback about the entire customer experience, including communication, system recommendations, installation quality and after-sales support.

Pay attention to reviews that mention individual electricians or explain how the company handled questions or unexpected challenges.

It's also worth looking at previous installations and case studies.

A company that can demonstrate experience across different property types and system configurations may be better equipped to identify potential challenges with your installation.

For example, Open Electrical has completed residential solar and battery projects throughout Brisbane, including system expansions, staged installations and larger-capacity battery systems.

These projects demonstrate why proper system design and installation experience matter.

8. Searching for the Top 10 Solar Installers in Brisbane?

If you've searched for the top 10 solar installers in Brisbane, you've probably come across several comparison websites and installer rankings.

These lists can be a helpful starting point, particularly when researching companies you're unfamiliar with.

However, not every ranking uses the same criteria.

Some focus on customer review scores, while others consider review volume, business participation or particular assessment methods or pay to be listed.

Rather than choosing a company simply because it appears on a top 10 list, take the time to investigate what sits behind the ranking.

A useful comparison should consider:

• Installer experience and qualifications
• Genuine customer reviews
• Quality of solar and battery equipment
• Installation methods and workmanship standards
• Warranty arrangements
• Local support and service availability
• Transparency of quotes and system recommendations

The best solar installer for your home isn't necessarily the company offering the cheapest price or appearing first in an online list.

It's the company that can demonstrate the experience, products and support needed to deliver a system suited to your property.

9. Know What Should Be Included in Your Solar and Battery Quote

A professional solar and battery proposal should explain exactly what you're purchasing.

Before signing, make sure you understand the proposed system capacity, equipment specifications, installation requirements and total cost.

Your quote should clearly identify:

• Solar panel brand, model and system capacity
• Inverter specifications
• Battery brand and usable storage capacity, where applicable
• Proposed equipment locations and system design
• Backup equipment and inclusions, if required
• Estimated electricity generation and savings assumptions
• Government incentives or rebates applied to the price
• Any additional electrical work required
• Warranty details and payment terms

For some properties, switchboard upgrades, additional wiring or other electrical work may be necessary.

These requirements should be discussed before installation wherever possible.

Be cautious of companies that pressure you into signing immediately or make significant savings promises without explaining how those figures were calculated.

A reputable installer should be willing to answer your questions and explain the proposal in terms you understand.

10. Choose a Local Installer Who Will Be There After Installation

Your relationship with a solar and battery installer shouldn't end once the system is switched on.

Over time, you may need assistance with system monitoring, technical questions, software updates or warranty claims.

This is where local experience and an established installation team can make a difference.

Before choosing an installer, ask who you'll contact if your system requires attention and whether the company has qualified electricians available to provide support.

For homeowners in Brisbane, Logan, Ipswich, Moreton Bay, Redlands, the Gold Coast and Sunshine Coast, choosing an established South East Queensland installer can make ongoing communication and servicing more straightforward.

At Open Electrical, our in-house electrical team and local support are an important part of the service we provide.

We're focused on building long-term relationships with our customers, not simply completing an installation and moving on.

Frequently Asked Questions

How do I choose the best solar installer in Brisbane?

Look for an established company with appropriately accredited installers, genuine customer reviews, quality products and transparent pricing. Ask who will complete the installation, what warranties are included and whether the proposed system is designed around your household's electricity usage.

Is it better to choose a solar installer with in-house electricians?

Using in-house electricians can offer advantages in quality oversight, consistency and accountability. However, subcontracted electricians can also provide excellent workmanship. The most important factors are installer qualifications, installation standards and clear responsibility for ongoing support.

What should I ask before buying a solar battery?

Ask about usable battery capacity, power output, compatibility with your existing solar system, blackout backup capabilities, monitoring features, warranties and installation requirements. The right battery should be selected based on your electricity consumption and household priorities.

Should I get multiple solar and battery quotes?

Yes. Comparing at least three detailed quotes is a useful way to understand differences in system design, equipment quality, pricing and after-sales support. Make sure you're comparing similar products and inclusions.

Can I add a battery to my existing solar system?

In many cases, yes. Whether a battery can be added depends on your existing inverter, electrical configuration, available installation space and the battery technology selected. An experienced installer can assess your current system and recommend suitable options.

Are solar and battery installers required to be accredited in Australia?

Solar and battery installations must meet relevant electrical safety and regulatory requirements. For access to applicable incentives under the Small-scale Renewable Energy Scheme, systems must be installed by appropriately qualified and accredited installers.
