Delayed installations, disputed workmanship: Australia's solar and battery trust problem

Buying solar or a home battery is meant to give a household more control over its electricity costs. Recent complaints involving Solar Power Nation and Lux Solar expose a different experience: uncertainty about delivery, disagreement over the finished work and difficulty finding a practical resolution.

The common issue is the distance between the sale and the outcome. A customer can have a signed contract, an apparently attractive incentive and a recognised brand, yet still struggle to obtain the system or service they expected.

This is a news analysis by SolarAnswers, drawing together our earlier coverage, ABC investigations and public regulatory records. It examines the points where a purchase can break down. It does not establish that every complaint is substantiated, that the businesses have committed the same conduct, or that these examples represent the performance of the entire industry.

Three stories that explain different parts of the problem

Our Solar Power Nation article examines disputed workmanship, unfinished work and the company's responses. It also sets out South Australia's public warning and the separate consumer-code record. The original ABC investigation is linked throughout that report.

The Lux Solar report concerns deposits and long installation delays, alongside the company's code status. The underlying ABC investigation was published two months after its Solar Power Nation story. These are separate sets of customer accounts and regulatory issues.

Our NSW ombudsman article adds the wider dispute-resolution context. It explains why a complaint about solar or batteries can encounter different pathways depending on the business and the issue involved.

Together, the stories raise questions about delivery, installation quality and access to remedies. They do not justify treating every large advertiser as unreliable or assuming that all complaints end with the same finding.

The national warning goes beyond individual companies

In its 10 July battery report announcement, the ACCC said reports about household batteries and new energy services had increased by 107% over 12 months. Problems included unsuitable systems, installation faults, poor performance and difficulty getting issues fixed.

The regulator also found benefits: many households with solar and batteries had lower electricity bills. Its concerns included complicated contracts and limited compatibility between batteries and virtual power plant products, which could make comparison and switching difficult.

This is an important distinction. Evidence that a technology can deliver useful savings does not establish that every sales process, installation or service contract works well. Equally, a rise in complaints does not prove that batteries generally fail to deliver benefits.

The numbers need their proper boundary. Reports received by a regulator are not a count of proven defects, and an increase in reports is not automatically an increase in the failure rate. That would require information about installations, complaint outcomes and comparable periods.

Problem one: the sale can get ahead of the delivery plan

A complete battery proposal needs more than an equipment price. It needs a workable site design, available components, an installation team, any necessary electrical or building work and a realistic sequence for completion.

If the quote leaves those matters open, a customer may believe they have bought a scheduled installation when the business has only begun arranging one. The disagreement becomes harder to resolve if the meaning of a deposit or a proposed date was never made clear.

This is a question of documentation as well as capacity. A delivery estimate should identify what still depends on a site visit, network approval, stock or another trade. If something changes, the revised proposal should explain the effect on timing, scope and price.

Our article on the next scheduled battery discount change explains why installation dates deserve attention. A deadline can add urgency, but urgency does not itself show that a retailer has the resources to complete the promised work.

Problem two: the system sold and the system installed can diverge

The written design is the reference point for comparing what a buyer agreed to with what appears at the property. A change of panel position, battery arrangement or inverter can affect more than appearance.

Sometimes a site inspection reveals a legitimate reason to change the design. The important questions then become whether the customer receives an explanation, what consequences are assessed and how agreement to the change is recorded.

An installation also has several possible finishing points. Equipment can be physically in place while commissioning, inspection, monitoring setup or an agreed item remains outstanding. Calling all of those stages "installed" can conceal the issue the customer is actually trying to resolve.

A useful handover should therefore make completion visible: what was fitted, what was tested, what documentation was supplied and what remains to be done. That gives both sides a more precise starting point if a dispute follows.

Problem three: an approval badge does not answer every question

The NETCC public register records expulsions for both Lux Solar and 1 Solar Australia, trading as Solar Power Nation. Those entries concern membership and obligations under the consumer code.

The federal Cheaper Home Batteries Program guidance describes separate safeguards involving eligible equipment, installer accreditation and electrical safety. It also identifies the involvement of the Clean Energy Regulator, Solar Accreditation Australia, the Clean Energy Council and state or territory safety regulators.

For a buyer, these checks answer different questions. The contracting company's identity, the installer's qualifications, product eligibility and current code membership should each be identifiable. A logo on a quote cannot substitute for all four.

The same care applies to online reputation. A review score may help a customer decide what to investigate, but it cannot show whether the proposed design is suitable or whether a particular installation has been completed correctly. Ask for evidence tied to the job, not only evidence of the seller's visibility.

Problem four: a complaint can become a second project for the customer

Once something goes wrong, the household has to explain the problem, identify the responsible business, gather records and find a service that can help. That effort can continue while the original equipment remains unavailable or disputed.

South Australia's August enforcement announcement illustrates the regulator's role: CBS described sector complaints, investigations and action involving several businesses. That kind of enforcement addresses conduct in the market. It is not the same as confirmation that a named customer's installation or refund has been completed.

This distinction matters when reading headlines about a crackdown. A warning, a code sanction, an investigation and an individual remedy are separate outcomes. One may lead to another, but they should not be reported as interchangeable.

Our NSW complaints coverage explains the membership limits on the ombudsman's service. The wider question is whether a household can reach a suitable dispute process without being repeatedly passed between organisations.

What stronger protection is being proposed?

The ACCC's July announcement called for broader ombudsman coverage, code participation tied to access to the federal battery program, and an overarching consumer duty supported by electricity-specific protections. Those are reform proposals described in that release, not a statement that every proposed obligation is already in force.

The intended direction is clear: make comparison easier, improve accountability and give consumers a workable route when an energy product or service goes wrong. Whether reform achieves that will depend on its detail and implementation.

For the existing voluntary scheme, our consumer-code article explains its role and limits. A code's existence is only part of the story; the practical questions are what happens after a breach and what assistance reaches the affected customer.

The evidence that would show an improvement

More confident advertising would not, by itself, answer these concerns. Useful evidence would include fewer unresolved delivery failures, clear records of agreed design changes, completed rectification and accessible complaint outcomes.

For an individual dispute, a meaningful update should state what happened: the system was commissioned, the defect was repaired, the agreed refund was paid or a decision was issued. A promise to contact the customer is a different milestone.

For a new buyer, ask for the same clarity before signing. The contract should let you identify the equipment, design, payment stages, completion arrangements and complaint contact. Keep later variations and handover records with it.

The industry problem exposed by these reports is that the purchase experience can break at several points while responsibility becomes harder to follow. A credible response needs to connect the sales promise to the finished job and the finished job to ongoing support. That is the standard by which future improvements should be judged.
