Origin Energy

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)

Resinc stands out as one of the top-rated and most popular solar installers nationally in 2026, based on verified customer reviews and SunWiz Awards data (with thousands of reviews). Other strong performers include SolarBright (top 10 nationally for ratings and popularity), RegenPower (high volume and popularity, especially in WA), and Sunboost (leading installer by volume in recent data).

Established names like Solahart (Canstar’s most satisfied customers winner for installers) and larger providers such as Origin Energy also rank well for customer satisfaction and reliability.

Always verify CEC (Clean Energy Council) approval for any installer or retailer, as this is the key consumer protection standard in Australia. Sites like SolarQuotes are popular for getting multiple competitive quotes from vetted local installers.

Top Solar Panel Brands People Actually Use

Installer surveys (e.g., SolarQuotes’ annual Installer’s Choice Awards) and real-world Australian reviews highlight these as the most recommended and used brands:

• Aiko Solar (Neostar series) — Frequently tops installer votes (e.g., 28% in 2026 awards, winning for the second year). Praised for strong efficiency (back-contact/ABC cell design), competitive pricing, solid warranties (typically 25 years product + performance), and value. Newer to the Australian market (launched ~2024) but quickly gained traction among installers for residential installs.

• Jinko Solar (Tiger Neo series) — Consistent top contender (often 2nd place). Excellent value, good efficiency, reliable Tier-1 quality, and widely available/used across Australia. Strong performer in reviews for performance and pricing.

• SunPower (Maxeon) — Premium pick (top 3 in installer votes). Highest efficiencies (often 22%+), industry-leading warranties (up to 40 years), and excellent long-term performance/degradation rates. More expensive but favoured for smaller roofs or maximum output.

• REC (Alpha series) — Strong premium/value option with excellent warranties, heat resilience, and reliability. Frequently recommended alongside Aiko/Jinko.

• Others commonly used: Trina Solar (solid mid-range/value), Q Cells (reliable with good Australian support), and LONGi or Canadian Solar (budget-friendly Tier-1 options that perform well in tests).

Inverters (a critical part of the system): Sungrow often leads installer preferences, followed by Sigenergy and Fronius for performance and features.

Key Tips for Choosing in Australia

• Focus on the installer over just the brand — A good local CEC-approved installer using quality components (Tier-1 panels + reputable inverter) matters more than chasing the absolute “best” panel. Poor installation voids warranties and causes issues.
• Warranties and specs — Look for 25+ year product and performance warranties (with low degradation rates, e.g., 0.25–0.5%/year). Efficiency around 20–22%+ is typical for modern panels.
• Costs and incentives — Expect ~$5,500–$9,500+ for a quality 6.6kW system (before/after STC rebate, which varies by location). Payback is often 3–6 years depending on state, usage, and feed-in tariff. Check state-specific rebates or programs (e.g., Solar Victoria).
• Batteries — Popular add-ons include Tesla Powerwall, Sungrow, or BYD for storage and higher self-consumption.
• Next steps — Get 3+ quotes from reputable platforms, check recent verified reviews (e.g., ProductReview.com.au or SolarQuotes), confirm local service/support, and compare total package (panels + inverter + install + warranty). Prices and availability can vary by state (NSW, VIC, QLD, etc.).

The Australian solar market is mature with strong competition, so focusing on highly reviewed installers using proven brands like Aiko, Jinko, or REC (or premium SunPower/REC) delivers reliable results for most households. Always do your due diligence with current quotes tailored to your postcode and roof.
