Solargain

As of September 2026, if I were buying solar for a typical Australian home, I’d separate “solar companies” into installer/retailer, panels, inverter, and battery. The installer matters as much as the hardware.

My shortlist: what I’d actually get quotes for

1) Best all-round solar panel brands

Safe mainstream picks: Jinko Tiger Neo, LONGi, Trina Vertex S+, JA Solar Deep Blue, Risen. These are widely quoted in Australia, reasonably priced, and have enough local track record to avoid most “mystery panel” risk. SolarQuotes’ current homeowner-review ranking has LONGi #1, Jinko #2, Aiko #3, Trina #4 and JA Solar #5, while SunWiz’s 2025 volume data names Jinko, JA Solar and Risen among the top-volume panel brands in Australia. (solarquotes.com.au)

Best performance/value upgrade: Aiko Neostar. Aiko won the 2026 SolarQuotes installers’ choice award for panels, with 28% of installer votes, ahead of Jinko and SunPower. I’d consider Aiko if the price premium over Jinko/LONGi/Trina is modest, especially where roof space is limited. (solarquotes.com.au)

Premium options: SunPower and REC. These make sense if you want higher-end hardware, cleaner aesthetics or long warranties and you’re not chasing the cheapest payback. SolarQuotes’ 2026 installer survey put SunPower third and REC fourth among installer-preferred panels. (solarquotes.com.au)

2) Best inverter brands

Best default inverter: Sungrow. It’s the current “safe value” pick for many Australian installs: strong features, common local use, good pricing, and it topped SolarQuotes’ 2026 installer inverter poll with 27% of votes. (solarquotes.com.au)

Best premium inverter: Fronius GEN24. Fronius is still one of the most respected inverter brands in Australia, even though it’s usually dearer than Sungrow/GoodWe/Solis. SolarQuotes notes Fronius was long considered the benchmark and remains strongly supported by installers. (solarquotes.com.au)

Best if you’re adding a battery now: Sigenergy Energy Controller / SigenStor or Sungrow hybrid. Sigenergy came second in SolarQuotes’ 2026 inverter poll and is popular because it bundles inverter, battery and energy management into a neat modular system. (solarquotes.com.au)

Best for shaded or complex roofs: Enphase IQ8 microinverters or SolarEdge. These cost more, but they can be worth it when you have shade, many roof faces, or want panel-level monitoring. SolarQuotes’ inverter comparison includes Enphase IQ8, SolarEdge, Fronius, Sungrow, GoodWe, Solis, Sigenergy and iStore as mainstream comparison options. (solarquotes.com.au)

Budget/value inverter: GoodWe or Solis. I’d accept these from a good installer, but I’d usually pay extra for Sungrow if the difference is small.

3) Best home battery brands

Best current shortlist: Sigenergy SigenStor, Sungrow, Tesla Powerwall 3, iStore, GoodWe.

• Sigenergy is very popular now: SolarQuotes’ 2026 installer battery picks put Sigenergy first, followed by Sungrow and iStore; SunWiz also reported Sigenergy as Australia’s #1 battery manufacturer by blended capacity in March 2025, with Sungrow, Alpha ESS and Tesla following. (solarquotes.com.au)
• Sungrow is the safer value pick if you want battery compatibility without paying Tesla money.
• Tesla Powerwall 3 is still a strong premium, app-friendly option, especially if you like the Tesla ecosystem.
• GoodWe is the cheaper battery brand I’d be most comfortable considering; SolarQuotes specifically calls it the cheapest battery brand they would comfortably recommend. (solarquotes.com.au)

For most Australian homes, I’d only add a battery if you have high evening usage, poor feed-in tariffs, blackout needs, EV charging plans, or access to good rebates/VPP deals. SolarQuotes currently describes 16–20 kWh as the “sweet spot” for households mainly trying to save money. (solarquotes.com.au)

Installers/retailers I’d look at

National or well-known retailers

For broad-name recognition, start with Solahart and Solargain. Canstar’s 2026 customer satisfaction survey rated Solahart #1, followed by Solargain, Origin Energy, Arise Solar and SolarHub. (canstar.com.au)

High-volume / widely used companies

If you want names that show up in volume rankings, SunWiz’s 2025 retailer/installer awards mention Sunboost, Sunbuilt Solar, Deionno Electrical, 1KOMMA5°, NSEG, Solar Power Nation, Think Renewable, Fritts Solar, Perth Solar Force, Solar Naturally and Perth Solar Warehouse across national and state categories. High volume does not automatically mean best workmanship, so treat this as a “people use them” list, not a quality guarantee. (sunwiz.com.au)

Highly reviewed local installers

SolarQuotes’ current “legendary rated” installers include RESINC Solar, Positive Energy Solutions, Brightworks Solar, Jet Solar, Goliath Solar and Electrical, Lenergy, Perth Solar Warehouse, Koala Solar, Chief Electricians and DSW Energy, based on review volume and average rating over the last three years. (solarquotes.com.au)

The combinations I’d ask for in quotes

Best value system:

• Panels: Jinko / LONGi / Trina / JA Solar
• Inverter: Sungrow
• Battery optional: Sungrow or GoodWe

Better performance system:

• Panels: Aiko Neostar or SunPower/REC
• Inverter: Fronius GEN24 or Sungrow hybrid
• Battery: Sigenergy, Sungrow or Tesla Powerwall 3

Complex roof / shade system:

• Panels: Jinko / Aiko / SunPower / REC
• Inverter: Enphase IQ8 microinverters or SolarEdge
• Battery: check compatibility carefully before signing

Non-negotiables before you sign

Make sure the installer is Solar Accreditation Australia accredited if you want government rebate eligibility, and check that the panels, inverter and battery are on the Clean Energy Council approved products list. The Australian Government also recommends getting at least three quotes, checking local after-sales support, and being cautious with cold callers, doorknockers and ultra-cheap heavily advertised deals. (energy.gov.au)

If you want the best solar companies in Australia based on what people actually use and rate well, the strongest names in the current results are Resinc, Solahart, RegenPower, Positive Energy Solutions, Solargain, and SolarBright.

A practical way to think about “best” is to split it into installers/retailers and panel brands:

If you’re asking for solar panel brands people actually buy in Australia, the strongest brands in the results are Aiko, Jinko, SunPower, REC, and Trina Solar.

Best choices by use case

• Best all-round installer: Resinc — it appears as #1 in SunWiz’s national popularity ranking and also as a top-rated installer on SolarQuotes.
• Best for customer satisfaction: Solahart — it won Canstar’s 2026 Most Satisfied Customers award for solar installers.
• Best for strong independent reviews: Positive Energy Solutions, Brightworks Solar, Jet Solar, and Goliath Solar and Electrical all have very high SolarQuotes ratings.
• Best panel brands: Aiko is the standout in installer-voted panel awards, with Jinko and SunPower next, followed by REC and Trina Solar.

What I’d recommend in Australia

• For a rooftop solar system, shortlist a strong installer such as Resinc, Solahart, RegenPower, or Positive Energy Solutions.
• For panels, ask for quotes with Aiko, Jinko, SunPower, REC, or Trina Solar options.
• Compare at least 3 quotes and check that the installer is accredited before signing.

If you want, I can turn this into a state-by-state shortlist for NSW, VIC, QLD, WA, SA, TAS, or ACT.

The best residential solar setup in Australia depends on whether you are prioritizing top-tier performance, value for money, or high-end technology. The most trusted brands currently dominating Australian rooftops are categorized by panels, inverters, and battery systems according to recent expert evaluations and data from SolarQuotes and Solar Choice.

🔧 Top National Solar Installers

Hardware only performs as well as the company installing it. When choosing an installation retailer, look for Solar Accreditation Australia (SAA) accreditation.

Solahart: Winner of the Most Satisfied Customers Award for national retailers; highly trusted for all-in-one solar packages. Solargain: Highly rated national runner-up that scores exceptionally well for setup logistics and after-sales customer service. Resync: Recognized for outstanding national consistency and high customer satisfaction ratings.

To recommend a specific system size and component configuration, let me know:

Your average daily electricity usage in kWh (found on your latest energy bill). Which state or territory you live in (to factor in local rebates and sunshine hours). Whether you are looking to include a solar battery right away or add one down the line.
