There is no single “best” solar panel for every Sydney home. The right panel depends on your roof space, budget, shading and what you want from the system. This guide explains what to compare, shows what some well-known panels offer according to their manufacturers, and gives indicative Sydney system prices.

Disclosure: Tally Energy Group is a solar installer and installs REC, Qcells and JinkoSolar panels. Those brands are listed first below because we install them. This guide is not a ranking, and no panel here is claimed to be the best. Ask us which panel suits your roof.

What to compare when choosing solar panels

Efficiency: how much sunlight a panel converts to electricity. It matters most when roof space is limited, because a higher-efficiency panel produces more from the same area.
Warranties: check both the product warranty (defects and workmanship) and the power warranty (how much output the panel is guaranteed to keep). Read the conditions: some manufacturers’ longest warranties apply only when the system is installed by a registered installer.
Temperature coefficient: how much output drops as the panel heats up. A smaller negative number (for example -0.24%/°C compared with -0.34%/°C) means less loss on hot days.
Approved products: only panels on the Clean Energy Council approved products list can be installed in systems that claim the federal STC rebate.
Manufacturer support in Australia: a warranty is only useful if the company is still around and has local support in 10 or 20 years.
Installer quality: installation matters as much as the panel. Roof layout, inverter pairing and workmanship all affect results.

Brands Tally Energy Group Installs

We install panels from REC, Qcells and JinkoSolar. The specifications below come from each manufacturer’s own datasheet, as checked in October 2026. Models, wattages and warranty terms change, and warranty length can differ by model and market, so confirm the exact model and its Australian warranty terms on your quote.

Panel	Efficiency (manufacturer)	Warranty (manufacturer)	Temperature coefficient
REC Alpha Pure-R (400–430 W)	22.3% maximum	25-year power warranty. Product warranty is 20 years standard and 25 years under REC ProTrust.	-0.24%/°C
Qcells Q.PEAK DUO ML-G11S.2 (495–515 Wp)	21.7% maximum	12-year product warranty. 25-year linear performance warranty: at least 98% of nominal power in year one, maximum 0.5% degradation a year, at least 86% at 25 years.	-0.34%/K
Qcells Q.PEAK DUO BLK M-G11S (390–410 Wp)	21.0% maximum	12-year product warranty. 25-year linear performance warranty: at least 98% of nominal power in year one, maximum 0.5% degradation a year, at least 86% at 25 years.	-0.34%/K
JinkoSolar Tiger Neo N-type (JKM425-445N-54HL4R-B, 425–445 W)	22.27% maximum	30-year product warranty and 30-year linear power warranty, with 0.40% annual degradation over 30 years.	-0.30%/°C

JinkoSolar also lists a newer Tiger Neo 3.0 residential range with efficiency of up to 24.52% and output of up to 490 W. We could not confirm its warranty terms from the manufacturer’s page, so ask for the datasheet if your quote includes it.

Other panels sold in Australia, with manufacturer-stated specifications

These panels are not part of our standard installer range. They are included so you can see how other well-known options compare on the same criteria, using the manufacturers’ own information.

Panel	Efficiency (manufacturer)	Warranty (manufacturer)	Temperature coefficient
Maxeon 6 AC (420–445 W, with factory-fitted Enphase microinverter)	Up to 23.0%	40-year limited product and power warranty. The microinverter has its own 25-year limited product warranty.	-0.29%/°C
Trina Solar Vertex S+ (455–520 W models)	Not stated on the page we checked	25-year product warranty and 30-year power warranty	Not stated on the page we checked
Tindo Walara (440 W G4P, made in Adelaide)	Not stated on the page we checked	25-year repair or replacement warranty	Not stated on the page we checked

“Not stated” means we could not confirm the figure from the manufacturer’s page, so we have not included one. Maxeon’s figures are for an AC module with a built-in microinverter, so they are not a like-for-like comparison with panels that connect to a separate inverter. Other brands, including LONGi and Canadian Solar, are also sold in Australia; we have not listed them because we have not confirmed their current specifications with the manufacturers.

Solar panel prices in Sydney (2026): indicative third-party data

The Solar Choice Price Index, an independent third-party index published on 1 October 2026, shows these average Sydney prices after the STC rebate, including GST. They are indicative averages, not Tally Energy pricing and not a quote:

System size	Indicative average Sydney price (Solar Choice, Oct 2026)
3 kW	$3,670
4 kW	$4,270
5 kW	$4,990
6 kW	$5,750
7 kW	$6,450
10 kW	$8,780

Your price depends on the panel brand, inverter, roof type, installation complexity and your installer. Premium panels typically cost more than budget panels, so compare quotes for the same system size and inverter.

The solar panel rebate gets smaller each year. Small-scale Technology Certificates (STCs) are calculated using a deeming period that counts down each year: five years for systems installed in 2026 and four years for systems installed in 2027, according to the Clean Energy Regulator.

For help choosing a size, see our 6.6kW, 10kW and 13kW system pages. To see how electricity prices and feed-in tariffs affect the value of solar, read Cost of Electricity in Sydney (2026).

Do solar panels work in Sydney’s heat?

Yes. Panels lose some output as they heat up, which is why the temperature coefficient is worth comparing between models. The difference between a -0.24%/°C panel and a -0.34%/°C panel is small in everyday terms, so treat it as one factor among several rather than a deciding one. Sydney weather data is published by the Bureau of Meteorology.

How Tally helps you choose

We recommend a panel after looking at your roof, shading, daytime electricity use and budget. We install REC, Qcells and JinkoSolar, and we will explain the differences between them for your home. When you request a quote, ask for the exact panel model, its datasheet and its warranty terms in writing so you can compare quotes properly. Request a free solar quote or call 1800 945 085.

FAQ: Solar panels in Sydney

What are the best solar panels for a Sydney home?

It depends on your roof space, budget and priorities. High-efficiency panels suit small roofs, while larger roofs can often get good results from lower-cost panels. Compare efficiency, product and power warranties, temperature coefficient and the manufacturer’s Australian support, and make sure the panel is on the Clean Energy Council approved list.

How much do solar panels cost in Sydney in 2026?

According to the Solar Choice Price Index (October 2026), average Sydney prices after the STC rebate are $4,990 for 5 kW, $5,750 for 6 kW, $6,450 for 7 kW and $8,780 for 10 kW, including GST. These are indicative third-party averages, not Tally pricing or a quote.

Do solar panels work well in Sydney’s heat?

Yes, though output drops slightly as panels get hot. The temperature coefficient on the datasheet shows how much, for example -0.24%/°C for the REC Alpha Pure-R, -0.30%/°C for the Jinko Tiger Neo N-type and -0.34%/K for the Qcells Q.PEAK DUO models according to their datasheets.

How long are solar panel warranties?

It varies by manufacturer and model. Product warranties on the panels above range from 12 years (Qcells Q.PEAK DUO models) to 40 years (Maxeon 6 AC) according to the manufacturers, and power warranties run for 25 to 40 years. Conditions apply, so read the warranty terms for your exact model and installer.

Does the solar rebate change each year?

Yes. The STC deeming period drops by one year each year, so the same system earns fewer STCs when installed in 2027 than in 2026 (five years for 2026 and four years for 2027, according to the Clean Energy Regulator).
