Jinko

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)

Here's a rundown of what's actually being installed and recommended by installers across Australia right now, based on the latest 2026 data.

Top Solar Panel Brands

Aiko is the brand to beat in 2026. Aiko Solar took out the top spot in the 2026 SolarQuotes Installers' Choice Awards, earning 27% of installer votes across Australia — a remarkable result for a brand that only launched in Australia in March 2024. Their standout feature is All Back Contact (ABC) technology, which improves performance—especially in partial shading conditions. The trade-off: the honest trade-off is track record — Aiko's technology is genuinely impressive and installer confidence is high, but the brand has less than two years of local history.

REC Solar is the long-standing premium choice. REC Solar has been a trusted name in the Australian market for well over a decade, and the REC Alpha Pure RX (470W) is their flagship panel, delivering 22.6% efficiency with a 25-year product warranty and strong salt-mist resistance — great if you're near the coast.

SunPower (Maxeon) rounds out the premium tier, taking 3rd place in installer votes, though there's a bit of history worth knowing: the SunPower business in the USA entered bankruptcy proceedings in 2024, but the SunPower brand and Maxeon have since been acquired by TCL, a Chinese company worth tens of billions, which will continue making high-end SunPower branded panels.

Jinko, Trina, LONGi, Q CELLS and Canadian Solar are the reliable "value" tier that most everyday Aussie households actually end up with. On a tighter budget, Jinko Tiger Neo and Canadian Solar HiKu7 are reliable Tier 1 options that will serve you well for 25 years. Trina in particular has strong staying power — Trina Solar has been a dominant force in Australia for decades, building a reputation around bankability, meaning financial institutions trust their longevity and warranty reliability.

If you want an Australian-manufactured option, note that if you're looking for an Australian-made solar panel the only option is Tindo Solar, who are only producing in small quantities.

Inverters & Batteries People Pair With Panels

For inverters, Fronius consistently comes up as the most trusted name — Fronius has one of the strongest reputations in Australian solar, built on a decade of premium inverters.

For batteries, Tesla and BYD are the household names most people pair with their panels, as noted alongside Fronius: you can pair them with premium batteries like Tesla or BYD, or top-tier inverters like Fronius—but if the panels underperform, your entire system suffers.

Quick Recommendation by Budget

• Premium/no compromise: SunPower Maxeon or REC Alpha Pure — if money is no object, SunPower Maxeon is the best panel you can put on an Australian roof, while for most households, the REC Alpha Pure-R or LONGi Hi-MO 7 offer a better balance of performance and price.
• Best all-rounder/highest installer confidence: Aiko Neostar — the Aiko Neostar 2S (455W) delivers 22.8% efficiency and a 25-year product warranty, with a temperature coefficient well suited to hot Australian summers.
• Solid value/mainstream: Jinko Tiger Neo, Trina Vertex, or Q CELLS.

Practical Tips

Since Aussie weather is mixed rather than sun

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.
