THIS new ALDI Solar deal could slash your electricity bills—but is it right for you?

As Australia passed a new milestone with over 4.16 million homes and businesses now sporting solar panels, a familiar supermarket brand entered the clean energy arena.

ALDI Solar launched in September 2025, promising simplicity with fixed-package solar and battery deals.

But in a mature and highly competitive market, is convenience enough to justify the switch?

ALDI Solar’s offering in detail

Unlike traditional solar installers who design systems tailored to each roof, ALDI Solar offered just two fixed packages.

Package 1 cost $6,999 and included a 10kWh home battery (2 x 5kWh modules) and a 6.6kW solar panel system with a 5.5kW hybrid inverter.

Package 2 cost $8,499 and came with a 20kWh battery (4 x 5kWh modules) alongside the same 6.6kW solar system and hybrid inverter.

Both packages included free blackout protection, though fire-resistant panelling cost an additional $385 for weatherboard or timber homes and $275 for two-storey houses.

All components carried 10-year product warranties and 25-year performance guarantees on the panels.

Installations were handled by Tempo, the company behind ALDI’s Stirling, Ambiano and Bauhm appliances, across Sydney, Newcastle, Wollongong, Melbourne, Brisbane, Gold Coast, Sunshine Coast and Canberra, with expansion to South Australia and Western Australia planned for 2026.

Why 2025 is different for solar buyers

The market had matured rapidly, with 3.2 GW of new rooftop capacity added in 2024 alone, pushing total installations past 4 million.

Average new rooftop systems now ranged from 8-11kW, making ALDI’s 6.6kW offering appear modest.

With $12.7 billion invested in new clean energy projects in 2024, including $9 billion in large-scale installations, competition had increased and costs had begun to fall.

The result was a market where quality standards were higher and experienced installers plentiful, giving homeowners more choices than ever.

Expert concerns

Peacock warned that ignoring roof size, direction, shading and other home-specific factors could reduce solar efficiency.

He noted that many Australians were now installing larger, more efficient panels, and that 6.6kW systems were often insufficient for homes aiming to go all-electric or charge electric vehicles.

Battery sizing also posed challenges. While a 20kWh battery suited most homes, a 6.6kW solar system struggled to keep it charged year-round.

Installation and warranty questions

ALDI selected installers on behalf of customers, limiting the ability to research companies or read prior reviews.

Installation quality could greatly impact system performance, yet ALDI’s model prevented homeowners from choosing their preferred installer.

Warranties were another area of concern. Components carried separate contracts via Tempo, potentially complicating service down the track.

The Altius brand panels, batteries and inverters remained largely unknown in Australia, raising questions about long-term reliability.

Peacock highlighted the 10-year panel warranty as a red flag, compared to the 20-25 year standard offered by reputable manufacturers.

Better timing, better options

Ironically, ALDI Solar launched just as government incentives and market competition were at their strongest.

Federal battery rebates and NSW’s VPP incentives could be combined to maximise savings, while rooftop and large-scale solar costs had fallen 2 and 8 per cent respectively in 2024.

Given over one-third of Australian households already had solar, buyers had the luxury of comparing multiple providers and customised systems.

Verdict for thoughtful buyers

ALDI Solar’s pricing appeared competitive, but the one-size-fits-all approach sacrificed customisation.

In a market with experienced installers, tailored systems, and generous rebates, careful comparison remained the smartest path.

Before committing, homeowners should get quotes from multiple established providers and weigh prices, warranties, component brands, installer reputations and system specifications against their roof and energy needs.

The solar revolution was well underway in Australia, but convenience alone should not dictate investment choices.
