Our Story

Founded in 2012, thiolstreg began with a straightforward mission: help Australians reduce their energy costs while contributing to a more sustainable future. What started as a small operation in Melbourne has grown into one of the region's trusted solar installation providers.

Over the past twelve years, we have installed solar systems on thousands of rooftops across Victoria, New South Wales, and Queensland. Each project has reinforced our commitment to quality workmanship and genuine customer service.

We believe solar energy should be accessible to everyone, not just those with technical knowledge or large budgets. Our team takes the time to explain options clearly, provide honest assessments, and deliver installations that perform reliably for decades.

What Drives Us

Our values guide every decision, from selecting equipment to training our technicians.

Quality First

We only install equipment that meets our strict performance standards. Every component is tested, every installation is inspected, and every system is backed by comprehensive warranties.

Honest Advice

We provide straightforward recommendations based on your actual needs, not sales targets. If solar is not right for your situation, we will tell you directly rather than push an unsuitable system.

Lasting Relationships

Solar systems last for decades, and so should our relationship with customers. We remain available for support, maintenance, and upgrades long after the initial installation is complete.

Environmental Commitment

Beyond our business operations, we actively support initiatives that advance renewable energy adoption across Australia.

Each solar installation contributes to reducing Australia's carbon footprint. Our installed systems collectively prevent thousands of tonnes of CO2 emissions annually, equivalent to taking thousands of cars off the road.

We participate in industry working groups advocating for policies that support renewable energy growth. We also contribute to educational programs that help communities understand the benefits and practicalities of solar energy.

Internally, our offices run entirely on solar power, and we implement responsible practices for recycling old equipment and minimising waste throughout our operations.
