Your bill keeps climbing — and you're right to be careful who you let on your roof.
- The bill never stops. Rising rates plus the aircon flat-out all summer — it only ever goes up.
- "Who do I even trust?" Cheap mobs, hard-sell reps, crews that install in a hurry and vanish. You've heard the stories.
- It's a confusing mess. Rebates, sizing, batteries, finance… you just want someone competent to sort it properly.
You don't want a sales pitch. You want a smaller bill — sorted properly, by people who'll still pick up the phone in ten years.

What Queensland homeowners say
"Well you were right Darren from Rethink Green Energy — I've had my second bill and I've saved $540 in the first quarter since you installed my solar system, and that was through the winter months. Can't wait to see what summer will do. Very happy with the service."
"Fantastic experience for our solar and battery install. Darrian gave top quality service from the first phone call to the home visit, explaining what system suited us best. Smooth and stress-free, and his honest advice really stood out. The aftercare has been excellent."
"Can't fault this company — super helpful and knowledgeable. Darrian fitted a 6.6kW unit 6 years ago, and I used him again for a much larger system on my new house. Very happy with the service and product."
"Awesome experience. Another fantastic job — fast, efficient, professional and great value. This is our fourth house completed by the company and their workmanship is second to none. Thanks Darrian and team."
"Cameron came and showed me how a solar and battery system could benefit our home. His transparency and approach to explaining how everything would work was on point — and everything ran so smooth."
"Excellent company and service. The entire process from quotation to installation was clear, informative and — most importantly — simple. Massive thank you to Darrian, Michelle and the Rethink Green Energy team."
"Outstanding service. Prompt and reliable, quick to problem-solve, and very patient even when faced with frustrating situations. I would strongly recommend this company."
"Was amazing to deal with — very open and honest about the cost and the install. Definitely recommend."
