About the company

Optimum Solar Energy was established from humble beginnings in 2014 as an electrical contracting business. The founder, Ryan, originally operated as a sole trader. The company Optimum Electrical Qld Pty Ltd was created due to demand and customer feedback. Optimum Solar Energy was established with a sole focus on renewable energy. Since 2017, the company has only offered solar services. Director and installer Ryan Orr has been in the industry since 2008. The company provides complete design, supply and install without subcontractors.

It offers a lifetime workmanship warranty and a lifetime performance guarantee on all work. The company specialises in sourcing and installing quality rooftop solar systems. It provides residential and commercial solar solutions, solar battery solutions for residential and commercial clients, and specialises in off-grid living solutions and solar-powered systems. The company provides solar installations in QLD and Northern NSW.

What customers say

Based on genuine customer reviews

Homeowners in Brisbane repeatedly highlight the depth of knowledge and the straightforward manner that Ryan Orr and his crew bring to each project, whether that involves a new rooftop array, an off-grid setup or the later addition of storage. Various customers describe the quoting stage as transparent and competitive, noting that explanations were thorough and that no unnecessary products were pushed.

The installation itself is often characterised as seamless from start to finish, with crews arriving punctually, working efficiently and leaving the site neat and tidy. A point that comes up often is the care taken with system design, from panel orientation and layout through to the exact height at which the inverter was mounted, and reviewers mention large configurations such as a 13kW array paired with a substantial Sigenergy battery, as well as individual systems fitted across a body corporate townhouse group.

Aftercare draws consistent praise, with follow-up support described as genuine and ongoing, and reviewers note that old equipment was removed at no extra cost. The work is variously described as reliable, well organised and completed on schedule even when the weather turned poor, while one account tells of a setup comfortably running two water pumps and two air conditioners in a sizeable residence.

We couldn't have been any happier with Ryan and his team's service. Ryan is very honest and didn't try to sell us something we didn't need with our solar and battery setup. We feel that he is very reasonably priced compared with others we had quotes from. We also liked the fact that this company has been around for quite a while unlike a lot of other solar companies. We also liked the fact that it was Ryan, the business owner, that completed the installation with care. Thanks again!

Happy to recommend Ryan and the Optimum team. They were put forward with 2 others through the 'solar quotes' website recommendations for a solar panel and battery install in Sept 2025. Ryan was easy to communicate with throughout, and he was willing to look into various options for what would best work with the roof space/orientation we had available. The install was done smoothly and the follow up service so far has been great. The guys even went above and beyond to help out with accessing a hard to reach part of our roof while they were there to make a quick adjustment on our security camera.

Optimum Solar Energy were fantastic from start to finish. The quote was clear and easy to understand, and their recommendations were tailored to our actual power bill and usage. I really appreciated that they didn’t try to over- or under-cook it, just the right system for our needs at a competitive price. The team showed up on time every day and worked across a few days to get everything installed properly. Professional, tidy, and respectful throughout. Both pre-sale and post-sale service have been impeccable. Questions were answered promptly and the follow-up after installation has been excellent. Couldn’t be happier, highly recommend Ryan and the team.

Ryan and the team at Optimum installed a large system on our roof recently. It was a seamless process from start to finish. Ryan is very knowledgeable and gave us confidence throughout the process all the way from the quote to getting hooked up to the grid. I’m getting him back soon to install a battery as well. Very highly recommend.

We had a fantastic experience with Ryan and the Optimum team from start to finish! They installed a 13kW solar panel system with a 24kW Sigenergy Battery at our home in inner-west Brisbane. The quoting process was easy and competitive, and the installation was seamless. After nearly two months, the system is running great, and we couldn't be happier. We no longer have to worry about high electricity bills and can run our ducted heating guilt-free. Bring on summer—the pool and air con will definitely be getting a workout! We were also particularly impressed when a minor issue with the gateway was sorted out instantly by Ryan over the phone. We can't recommend them highly enough!

I highly recommend Optimum Solar! From the very first meeting, Ryan Orr was approachable, friendly, and took the time to explain everything clearly. He and his crew arrived right on time, worked efficiently, and left everything neat and tidy. The installation was completed without a hitch, and what really stands out is the aftercare. Ryan goes above and beyond with his follow-up support—nothing is too much trouble, and he genuinely cares about his customers. Excellent service from start to finish!

We had a fantastic experience with Ryan and the team at Optimum Solar. In March 2025 we had them install individual solar systems across our group of townhouses through the body corporate. The process was smooth from start to finish and Ryan was a pleasure to work with throughout. He was responsive, professional and straightforward in answering all my questions and provided a competitive quote. The committee was confident in choosing Optimum for the job. Through the installation, the team were professional and worked hard to complete the installation across all units on time and to a high quality. All units are happy with the results. Like all the other reviews, I highly recommend Ryan and his team.
