Why Sydney Is a Strong Market for Solar in 2026

Solar in Sydney is shaped by a few verifiable 2026 changes. These figures come from the regulators and price trackers named below, not from Tally pricing.

• Typical system prices (Solar Choice, October 2026, Sydney, after STCs, incl. GST): 3kW $3,670; 4kW $4,270; 5kW $4,990; 6kW $5,750; 7kW $6,450; 10kW $8,780. These are third-party indicative averages, not Tally prices.
• Electricity prices: the 2026–27 Default Market Offer from the Australian Energy Regulator (AER) puts the benchmark annual bill at $1,899 in the Ausgrid area (3,900 kWh) and $2,328 in the Endeavour area (4,900 kWh), each down 3.4%.
• Feed-in rates: IPART’s 2026–27 benchmark range is 3.4–6.5c per kWh, down from 4.8–7.3c.
• STC discount: the deeming period used to calculate Small-scale Technology Certificates is 5 years for systems installed in 2026 and 4 years in 2027, so the upfront discount reduces over time.
• Home batteries: the federal battery rebate steps down from 1 January 2027.

Savings depend on your usage, tariff, roof and system size. Our cost of electricity in Sydney guide sets out the AER and IPART figures in more detail.

Sydney’s Top Solar Companies (2026 – Quick Comparison Table)

This comparison table shows ten companies side by side so you can identify installers worth requesting quotes from. Ratings and brands are from the sources named below, as at 4 October 2026.

Ratings and brands are as published on each company’s SolarQuotes profile on 4 October 2026 and change over time. Review counts are SolarQuotes ratings and are not Tally figures. Brand lists show what SolarQuotes lists as currently installed, not an endorsement.

⭐ How We Compiled the Top 10 Solar Companies in Sydney

To compile this list of the top 10 solar companies Sydney offers in 2026, we looked at publicly checkable information for each company:

• Customer reviews: ratings and review counts on SolarQuotes, with the date shown. We encourage you to also check Google and ProductReview.
• Panel & inverter brands: the brands each company lists as currently installed.
• Service area: head office and the NSW regions each company says it serves.
• Licensing and accreditation: verify these yourself (see the checklist below), as we cannot confirm them for you.
• System options: solar, battery and hybrid systems.

Tally Energy Group is our #1 pick. The other nine companies appear in no particular order of quality.

What Makes a Solar Company Reliable in Sydney?

Not all solar companies are the same. The right installer for you is the one that quotes clearly, uses products with solid warranties, is properly licensed and accredited, and stays contactable after installation.

“Tier-1” is a bankability classification for manufacturers published by BloombergNEF. It is not a guarantee of installation quality, so even a good panel can underperform if it is poorly installed. That’s why it pays to check reviews, experience in NSW suburbs, written warranty terms and clear communication before you sign.

When you compare the top 10 solar companies Sydney homeowners can choose from, look at the whole quote – components, warranties, what is included and what is not – not just the price.

How to Choose the Best Solar Company in Sydney

Choosing the best solar installer in Sydney for your home comes down to installer accreditation, licensing, panel and inverter quality, pricing transparency, and long-term warranty support. Here’s a checklist for verifying any installer, including Tally.

Experience in Sydney

Local teams understand rooftops, suburbs and grid connection requirements. Check where the company is based and who will do the work on your roof.

Panel Brands and Warranties

Ask for the exact panel model and read the manufacturer’s product and performance warranty. Brands listed in this guide include Jinko, Trina, LONGi, Qcells, REC, SunPower, Aiko and JA Solar. Panels Tally installs are REC, Qcells and Jinko.

Inverters

Ask for the inverter model, its warranty, and whether it suits future battery additions. Brands listed in this guide include Sungrow, Fronius, Enphase, Sigenergy, Fox ESS and SolarEdge.

Accreditation and Licensing

Ask for the installer’s Solar Accreditation Australia (SAA) accreditation details and NSW electrical contractor licence number, and check them with the issuing bodies. Accredited installation is required for your system to be eligible for STCs.

Transparent Pricing

Get a written quote showing brand and model names, system size, what is included and the STC discount. Compare at least three quotes, and avoid companies that won’t name the products.

Warranty and Support

Solar systems are meant to run for many years. Check who handles warranty claims, how to contact them, and read recent reviews on more than one platform.

Conclusion

Sydney has plenty of solar installers offering a wide range of systems and prices. In 2026 the STC discount is stepping down, the home battery rebate steps down from 1 January 2027, and feed-in rates have dropped, so it helps to compare quotes carefully.

Tally Energy Group (TEG) is our #1 pick, with REC, Qcells and Jinko panels, a choice of six battery brands and systems matched to each home’s needs.

Whether you choose TEG or another provider from this list of the top 10 solar companies Sydney homeowners can compare, make sure the installer is accredited and licensed, names the panel and inverter models in writing, and puts warranties in the quote.
