TW Solar Panels in Central Queensland
At Reef Solar & Electrical, we supply and install TW Solar panels for homes and businesses across Gladstone, Rockhampton, Yeppoon, Agnes Water, Tannum Sands, Boyne Island, and surrounding Central Queensland. We design systems that suit your roof, your usage and your budget, with clean workmanship, quality components and local after-sales support.
- Designed for Queensland Conditions: We select TW Solar panel options suited to heat, humidity and coastal conditions, paired with quality mounting and cabling.
- More Power From Your Roof: High-efficiency panel options help maximise production where roof space is limited.
- Neat, Safe Installs: CEC-accredited design and installation with compliant isolators, labeling and switchboard work.
- Better ROI: We build the system around your usage (daytime vs evening), tariff, and future needs (battery-ready if required).
- Built for harsh weather: TW panels are Salt Mist certified to Level 8 (highest rating for coastal regions) and hail tested to 45mm at 110km/h. Many panels only meet 35mm.

TW Solar panel options & system sizing
Popular system sizes we install
- 6.6kW Solar: A great starting point for many homes, solid daytime coverage and a strong return in Central QLD.
- 10kW Solar: Ideal for larger households, higher usage, or those wanting to maximise savings.
- Battery-ready design: We can size and configure the inverter/switchboard so you can add a battery later if it makes sense.

Customer Feedback
Very happy with my solar installation. They were very helpful when I received my quote, happy to explain any questions I had about the different options. His team arrived on time and done a fantastic job. Would highly recommend.
Thank you so much. We are very pleased with the work done by your expert friendly team installing our solar system. All the way through the job was done in a very professional manner. Will recommend to anyone else. Many thanks.
Everything from the initial contact to the installation of our Solar System and follow up were exceptional. They were on time and provided all the information we needed to make the decision to have Solar installed. The installation was done over two days with the utmost professionalism and quality.
They are good guys, they’ll talk to you plainly and has the patience to explain and not stick to industry jargon. He won’t pressure you (I waited over 6 months between his consult and my install, saving up funds needed), he’s quite happy for you to do own research and answer questions after that. I got 3 solar quotes, looked deeply into solar components in that time between. They got my business with quality components and a prompt install that cleaned up after themselves.
Excellent professional service, prompt installation. Highly recommend…
Absolutely fantastic company to deal with. I had a 6.6kWh Solar system installed. They were very knowledgeable, flexible, professional, and prompt. Sold the system by promoting their skills and not running down the opposition. System was installed 2 weeks after ordering and the workmanship was outstanding. The system performs better than expected.
