Solar panel installers in Australia 2026: a fact-based ranking
A ranking of solar panel installers in Australia, based only on facts from official company sites and public registers. Only companies that carry out the installation themselves are included, without lead-generation or comparison sites. The legal entity is confirmed by its ABN or ACN; qualification means Clean Energy Council or Solar Accreditation Australia installer accreditation, or approved seller status, as stated by the company. Some sites are closed to automated checks, so those companies may be missing; this is no judgement of their work. We do not verify stated figures on site, and reviews and promised savings are not counted. Compare Score only within Australia. Score is not for sale; paid placements, if any appear, will be a separate labelled block.

How we calculate the Score
30%
Trust
Whether the legal entity and registry number are stated on the site or found in a public register, whether a trade qualification of the installers is stated (for example UDT certificates in Poland, Handwerksrolle entry in Germany, SRO membership or a licence in CIS countries), and years on the market (full marks from 20 years). ISO 9001 and manufacturer partner badges do not count as a qualification.
25%
Warranties
The company's own warranty on the installation work (full marks from 10 years) and the linear performance warranty on the panels it installs (full marks from 30 years). The work warranty weighs three times more because the installer itself stands behind it.
15%
Track record
Stated cumulative installed capacity (log scale up to 1 GW) and stated number of installations (log scale up to 100,000). These are the companies' own figures; we do not verify them on site.
15%
Services
Whether there is a turnkey offer from design to grid connection, service or monitoring after installation, help with credit, leasing or a subsidy, and whether concrete panel and inverter brands are named.
15%
Transparency
Whether at least one concrete price or example offer is published without a form, whether the way to file a complaint is described, and how many contact channels are stated: phone, email, chat or messenger, web form.
How to choose a solar installer
Compare offers line by line
Ask for several offers for your roof and compare capacity, panel and inverter brands, mounting, labour and grid connection.
Check the legal entity and the contract
Match the company name and number against the register. See who is responsible for the work if it is passed to a subcontractor.
Keep warranties apart
Warranties on the work, the panel product, panel output and the inverter are separate, with different terms. Ask who honours each one and how.
Confirm permits and subsidies
Grid connection rules and subsidy terms change. Check them with the grid operator and the official programme, not only with the seller.
Frequently asked questions
What does first place mean?
The company in first place has the highest Score under our open methodology among companies in that country. It means more verifiable facts and better stated terms; it does not guarantee the quality of a specific installation.
Why don't you show savings or payback?
Yield and payback depend on the roof, region, tariff and consumption. Companies' promises cannot be compared, so we leave them out. Work them out separately for your home.
Where do capacity and installation figures come from?
They are the companies' own statements on their official sites. We give the source and date but do not inspect sites. If a figure is not published, the card shows “Not verified” and it earns no points.
Can I compare companies from different countries?
No. Installer requirements, registers and subsidies differ by country, so Score only makes sense within one country.
