Australia is rapidly emerging as one of the global leaders in renewable energy, with solar power in Australia becoming an increasingly popular choice for households and businesses alike. Thanks to the country’s abundant sunshine, vast open spaces, and strong government incentives, more Australians are turning to solar as a clean, cost-effective alternative to traditional energy sources.
Over the past decade, the industry has expanded significantly, offering customers a wide range of options for solar panels, inverters, and complete energy systems.
In this guide, we’ll explore the top solar power companies in Australia, carefully reviewed based on their product quality, customer service, installation expertise, and overall value for money. Whether you’re considering solar power companies in Australia for a residential setup or a large-scale commercial project, our insights will help you choose the right provider for your energy needs.
Why Solar Power is Booming in Australia
Australia’s solar surge reflects a national shift toward renewables. In 2022, solar power generated about 14.7% of the country’s total electricity, with renewables now making up 41% of renewable electricity, and rooftop solar (<100 kW) leads the charge at 19.4 GW total capacity across 3.36 million installations. Emboldened by rising electricity prices, households are switching to solar for lower bills, environmental benefits, and greater energy independence.
Switching to solar offers clear advantages: significantly reduced energy costs, lower carbon emissions, and freedom from utility price volatility—especially when paired with battery storage.
Demand for Australian-made solar panels is also growing. Companies like Tindo Solar (South Australia) are expanding their network and pitching their locally built panels on quality and region-tailored durability.
Moreover, solar has become much more affordable over the past decade: in Australia, the levelized cost of residential PV electricity dropped 58% from 2010 to 2020, while global solar costs fell by over 80%

How We Selected the Top Solar Companies
We evaluated leading solar providers in Australia using a clear set of criteria. First, we assessed the quality of solar panels and systems, focusing on efficiency, durability, and Australian climate suitability. Customer service and installation expertise were key factors, along with warranty coverage and after-sales support for long-term reliability.
We also considered pricing transparency to ensure fair, upfront costs with no hidden fees. Our review includes both large-scale solar power station providers and residential solar installers, giving a complete view of the market for all types of energy needs.
Comparing Solar Power Costs in Australia
In Australia, a typical residential system (5–10 kW) bundles hardware (panels, inverter, racking), labour/installation, balance of system (cabling, isolators, monitoring), and after-sales support/warranty. On average, hardware makes up ~55–65% of the bill, installation 20–30%, and the rest covers compliance, overheads, and margins—figures vary by home and installer.
What pushes prices up or down?
Panel efficiency and brand tier, inverter type (string vs. hybrid/microinverters), roof complexity (tile vs. tin, multi-storey), travel distance, grid/inspection fees, and seasonal demand. Quality components and stronger warranties usually add cost but improve long-term yield.
Indicative 6.6 kW turnkey price (post-rebate) by provider tier:
- Budget-focused: AU$4,500–6,000 — entry panels/inverter, minimal extras.
- Mid-tier value: AU$6,000–8,000 — reputable brands, solid warranties.
- Premium/performance: AU$8,000–11,000 — high-efficiency panels, hybrid/battery-ready inverters, superior support.
Australian-made vs imports: Solar panels Australian-made care~10–20% higher upfront than mass-imported panels, reflecting local manufacturing costs and support. However, they often offer robust local warranties, supply-chain transparency, and easier service, which can improve lifetime value. This snapshot helps frame solar power cost comparisons across installer tiers.
Tips for Choosing the Right Solar Company
Selecting the right solar company can make all the difference in your investment. Start by checking the warranties and certifications – reputable solar power companies in Australia should offer product warranties of at least 10–25 years and hold Clean Energy Council (CEC) accreditation.
