The best solar electricity providers
The brands rated are listed below in order of best overall satisfaction.
1. Lumo Energy

Lumo Energy is this year’s winner in terms of overall satisfaction.
Lumo Energy is one of two electricity retailers owned by renewable energy generation company, Snowy Hydro – the second being Red Energy. Although Lumo Energy doesn’t sell any solar-specific plans, it does offer solar feed-in tariffs (FiTs) across its market offers on top of competitive electricity usage and supply rates.
Lumo only offers plans in Victoria and South Australia, which have no contract terms or exit fees, and customers have access to flexible billing and payment options. The retailer frequently offers welcome or bonus credits for new sign-ups, along with its Lumo Rewards loyalty program.
2. OVO Energy

OVO Energy is the winner of the 2026 Most Satisfied Customers Award in the ‘Best Energy Provider for Solar’ category. However, it sits in second place when it comes to overall satisfaction.
First launched in 2009 in the UK, OVO Energy offers a handful of novel electricity and solar plans, with features such as default bill smoothing, free electricity during peak times and lower rates for EV owners in the evening. OVO Energy also pays customers with excess credit a three per cent bonus interest.
3. Red Energy

Red Energy is a well-rounded retailer, offering competitive electricity rates as well as moderate feed-in tariffs in New South Wales, Victoria, Queensland and South Australia. Red Energy’s other selling points include its partnership with Qantas, along with other tailored electricity plans such as its EV plan. Red Energy is our third-place winner for overall satisfaction.
4. ActewAGL

Canberra-owned energy provider, ActewAGL, sells its electricity and natural gas plans in the Australian Capital Territory and southeast NSW (e.g. Queanbeyan, Goulburn, the Snowys, Nowra, and South Coast). In the ACT, ActewAGL’s electricity plans boast competitive rates, followed by moderate solar feed-in tariffs (FiT) and ongoing benefit periods. ActewAGL sits in fourth place for overall satisfaction.
5. Origin Energy

One of the ‘big three’ retailers across Australia, Origin Energy offers two solar-specific deals in NSW, QLD, ACT, VIC and SA called Go Solar Variable and Solar Boost. Not all plans may be available in all states at all times. Origin also assists customers looking to buy solar panels, batteries, inverters and home monitoring systems, alongside offering competitive electricity plans. In 2026, Origin made it to fifth place in our shortlist for overall satisfaction.
6. AGL

As one of Australia’s largest electricity, natural gas and solar retailers, AGL offers a diverse range of energy products to suit varying households across NSW, VIC, QLD, and SA. Customers who are interested in AGL’s energy and mobile or home internet plans are eligible for a monthly bundle discount. AGL also offers a range of solar panel, battery and installation deals to customers. AGL takes home sixth place for overall satisfaction.
7. EnergyAustralia

Formerly known as TruEnergy, EnergyAustralia is one of Australia’s largest electricity and natural gas retailers. EnergyAustralia’s plans are typically known for competitive rates and value-added incentives such as guaranteed discounts, with solar-specific plans offering generous solar FiTs. EnergyAustralia also works with external solar installers and experts to offer rooftop solar and battery installation services. EnergyAustralia placed seventh this year for overall satisfaction.
8. Aurora Energy

Aurora Energy is a government-owned Tasmanian electricity and natural gas retailer. While the Tassie energy market remains price-regulated, there are currently eight retailers due to competition deregulation. Aurora Energy’s plans frequently include high solar FiTs and direct debit discounts. Two out of its three plans also offer customers access to the Aurora+ app — a convenient hub for managing bill payments and monitoring energy use and solar exports. Aurora Energy is currently in eighth place for overall satisfaction.
9. Alinta Energy

Alinta Energy operates across NSW, VIC, QLD, NSW, SA, in addition to selling gas in Western Australia. The retailer tends to offer competitive rates and simple plans, including a solar-specific option with a stepped solar feed-in tariff. All Alinta plans are contract-free and include variable rates. Alinta customers also have access to the newly-revamped Alinta Energy rewards program. Alinta made it to the ninth spot in terms of overall satisfaction.
10. Synergy

Synergy is one of two government-owned electricity retailers in competition and price-regulated WA. However, Synergy does offer some unique plans, such as the Electric Vehicle Add-On plan with lower rates during the day for EV owners and the Home Business Plan with a block-rate tariff. Synergy earned tenth place for overall satisfaction.
11. Engie

Engie maintains a range of energy offers, such as deals exclusive to NRMA members in some states. The retailer offers solar-specific plans in NSW, VIC, QLD and SA, which come with higher solar feed-in tariffs. Aside from its solar offers, Engie’s market offer plans include average solar feed-in tariff rates, but competitive electricity usage and supply costs. Engie sits in 11th place for overall satisfaction.

Ergon Energy is both the sole electricity distributor and provider in regional QLD, with regional prices managed and regulated by the Queensland Competition Authority (QCA).

Ergon Energy closes off the list at twelfth place for overall satisfaction.
