Australia’s Clean Energy Regulator (CER) has taken decisive action against the nation’s burgeoning solar industry, suspending 21 companies from the Small-scale Renewable Energy Scheme (SRES) this August. The crackdown comes amid a surge in consumer complaints regarding shoddy workmanship, unrefunded deposits, and systems that failed to operate as promised. In a significant move to bolster compliance, the CER has also confirmed the deployment of artificial intelligence (AI) to scrutinise battery installation photographs, directly addressing potential fraud in the rapidly expanding home battery market.
The suspensions underscore a critical effort by the regulator to maintain the integrity of Australia’s solar sector and protect consumers. The affected companies were found to no longer meet the stringent “fit and proper person” requirements of the SRES. Furthermore, separate investigations have been launched into allegations that some solar systems were declared complete and capable of generating electricity when they were not.
Leading Retailer Under Fire: Solar Power Nation Investigations
Among the companies facing scrutiny is Solar Power Nation, a major retailer operating under at least four different names, which has garnered hundreds of complaints across multiple states. According to reports, South Australia’s Consumer and Business Services (CBS) received 94 complaints about Solar Power Nation and its affiliates between July 2025 and April 2026.
“From July 2025 to April 2026, South Australia’s Consumer and Business Services (CBS) body received 94 complaints about Solar Power Nation and related companies. The ABC’s 7:30 Report on Thursday additionally revealed that NSW’s Building Commission has received more than 240 complaints about the company since 2024.”
The nature of these complaints ranged from customers paying deposits for installations that never materialised within a reasonable timeframe (41 cases in SA) to products that either never worked or ceased functioning shortly after installation (26 cases in SA). Other grievances included significant delivery delays, ignored requests for refunds or warranty claims, and unsafe installations that the company failed to rectify.
These allegations, which remain under active investigation by the CBS, NSW Building Commission, Queensland’s Office of Fair Trading, and the federal Clean Energy Regulator, highlight the urgent need for consumers to exercise due diligence when selecting an installer. Solar Power Nation attributed some delays to a surge in demand following the April 30, 2026, rebate cuts, a common industry challenge. However, this explanation failed to account for complaints related to faulty products or inadequate aftercare.
AI Steps In: Bolstering Compliance with Technology
To combat such issues and ensure compliance across the vast number of installations, the CER’s compliance systems now oversee more than 4.2 million rooftop solar installations nationwide. The regulator has specifically started using AI to verify battery installation photographs. This technological intervention is crucial given the rapid growth in the sector; the first quarter of 2026 saw approximately 77,000 small-scale solar systems adding a record 791 megawatts of capacity.
The integration of home batteries has also seen a significant uptick, with 71% of solar systems installed in Q1 2026 now including a battery. Over 460,000 batteries, representing 12.8 gigawatt-hours of storage, were installed between July 1, 2025, and June 8, 2026. This robust growth necessitates advanced verification methods to prevent fraudulent claims and ensure that systems meet safety and performance standards.
What This Means for Australian Homeowners
Australia boasts the highest uptake of household solar globally, with rooftop solar becoming an indispensable component of the nation’s renewable energy transition. While incentives like Small-scale Technology Certificates (STCs) have made solar more accessible, the recent crackdown serves as a stark reminder of the importance of choosing reputable and accredited installers.
Homeowners considering a new solar system or a battery retrofit should:
- Verify Credentials: Always ensure your chosen installer is accredited by the Clean Energy Council (CEC). This provides a level of assurance regarding their qualifications and adherence to industry standards.
- Understand Contracts: Thoroughly review all contractual agreements, including payment schedules, warranty provisions, and installation timelines, before committing. For more details on installation costs, refer to our guide: Solar System Installation Costs in Australia 2026: A Complete Guide.
- Be Wary of Low Prices: While competitive pricing is desirable, unusually low quotes can be a red flag for potential shortcuts or substandard components. Compare multiple quotes and assess the value proposition.
- Check References and Reviews: Seek out independent reviews and ask for references from previous customers to gauge an installer’s reliability and quality of work.
- Monitor Performance: Once installed, regularly monitor your solar system’s performance. Underperforming systems can indicate issues that need addressing.

The CER’s proactive measures, including the use of AI for compliance checks, aim to foster a more transparent and trustworthy solar market. This will ultimately benefit consumers by reducing the risk of substandard installations and ensuring the continued growth of high-quality renewable energy solutions across Australia.
