Hello neighbours! It’s Gigi. Lately, I’ve been getting a lot of questions about finding a trustworthy solar installer here in Brisbane. It’s a big investment, and let’s be honest, the number of options out there is enough to make anyone’s head spin. Who can you trust to be on your roof? What products are actually worth the money?

I’ve spent a lot of time digging into this, speaking with industry experts and homeowners to get a clear picture of the local market. My goal is to help you cut through the noise and feel confident in choosing the right team for the job. So, let’s walk through some of the best solar companies in Brisbane and what makes them stand out.

Finding the best solar companies in Brisbane

When I started my research, I looked for companies with a long-standing reputation, consistently positive customer reviews, and a commitment to high-quality components and installation standards. In Brisbane, a few companies are regularly praised for their professionalism and workmanship.

MC Electrical, Gem Energy, SolarGain, and Solar Union are all prominent names in the Brisbane solar scene. They are known for using quality equipment and having experienced, in-house teams of installers. This is a crucial point, as companies that use their own SAA-accredited electricians often have better quality control compared to those who subcontract out their installations.

Solar Union Brisbane reviews

Solar Union receives strong praise in customer reviews for their professionalism and knowledge. Customers frequently mention a smooth process from the initial consultation to the final installation, highlighting the helpfulness of the team in explaining system choices and even assisting with finance steps. Many reviews commend the company for its friendly, efficient, and tidy installation crews. Reviewers often state they would happily recommend Solar Union to friends and family, pointing to good communication and a no-pressure sales approach.

MC Electrical Brisbane reviews

MC Electrical is one of the most highly-regarded solar installers in Brisbane, consistently earning top marks from customers. Reviews frequently describe their process as professional and consultative, from the first phone call to the post-installation support. Customers appreciate that they aren’t pushy and are open and honest about their products. Their installation teams are praised for being knowledgeable, polite, and respectful of property, often going the extra mile to ensure a neat and tidy setup. The company is also noted for its excellent after-sales service, promptly helping customers with any issues that arise.

SolarGain Brisbane reviews

SolarGain customers often report a professional and attentive experience. Reviewers highlight the company’s helpfulness and knowledge from the quoting phase through to installation. Many have been impressed with the installers’ commitment to a great outcome and their care in ensuring the system looks neat on the roof. Solargain is also described as being a great company to deal with, demonstrating excellent customer service before, during, and after the installation is complete.

Gem Energy Brisbane reviews

Gem Energy consistently receives positive feedback for its smooth and communicative process. Customers note that the team is helpful in explaining the best solar package for their needs and keeps them informed from the sales process right through to post-installation. Reviewers have described the installation crews as knowledgeable and friendly. As a company that handles large-scale commercial projects, such as for Australia Zoo and the Brisbane Convention and Exhibition Centre, they bring a high level of expertise to their residential installations.

New Energy Tech Consumer Code (NETCC) approved sellers in Brisbane

It’s really important to choose a company that is committed to high standards. The Clean Energy Council’s ‘Approved Solar Retailer’ program has been replaced by the New Energy Tech Consumer Code (NETCC) program. This is a voluntary scheme that holds solar retailers to a higher standard of service and consumer protection.

When you choose a NETCC Approved Seller, you have peace of mind knowing they have committed to honest sales practices, a minimum five-year whole-system warranty, and will provide the necessary support if issues arise. I can confirm that MC Electrical, Gem Energy, and SolarGain are all listed as NETCC Approved Sellers. Solar Union also holds this important accreditation. You can always check the official NETCC website for a current list of approved sellers in your area.

They also offer Sungrow inverters as a reliable, mid-range option.

In 2025, they were recognised as the third-best solar installer in Queensland in the SolarQuotes Installers Choice Awards. Their longstanding partnership with Fronius as a Solutions Partner Plus also speaks to their high level of expertise and service.

Solar Union Brisbane awards

While Solar Union doesn’t have a public list of formal awards, their consistent 5-star customer ratings across multiple platforms act as a strong endorsement from the Brisbane community. Their status as a NETCC Approved Seller and Master Electrician also demonstrates a commitment to industry best practices.

SolarGain Brisbane awards

SolarGain has an impressive track record when it comes to customer satisfaction awards. They have been recognised with the Canstar Blue ‘Most Satisfied Customer’ Award for solar installers multiple times, including in 2021, 2022, 2024, and 2025.

Their expertise has also been recognised through their involvement in major commercial projects for iconic Queensland locations.

Brisbane solar company financing options

The upfront cost of a quality solar system can be a hurdle, but many Brisbane companies offer financing to make it more accessible.

• Green Loans: These are personal loans offered by banks and credit unions specifically for renewable energy installations. Companies like MC Electrical and SolarGain can facilitate these types of loans.
• Interest-Free Finance: Some companies partner with providers like Nectr or Humm to offer interest-free payment plans. MC Electrical offers a genuine interest-free option through Nectr, where the price of the system is the same as paying cash.
• Flexible Payment Plans: Gem Energy offers a range of finance options, including no-upfront payment plans and terms ranging from 1 to 30 years.
• Buy Now, Pay Later (BNPL): Services like Brighte and Humm are sometimes used by solar installers to offer flexible repayment schedules.
• Power Purchase Agreements (PPAs): More common for commercial installations, a PPA allows a business to have a solar system installed with no upfront cost and simply pay for the energy it generates.

Solar Union notes that they can assist with the “finance steps,” suggesting they have processes in place to help customers arrange payment, likely through one of the common methods above. They encourage homeowners to consider that if you can afford your power bill, you can afford to invest in solar, often with financing that results in manageable repayments.
