ET Solar panels are gaining attention for their performance and value. Reviews of ET Solar panels in Australia highlight their cost-effectiveness and efficiency.
ET Solar panels are increasingly recognised in Australia for their efficiency, reliability, and value for money. Known for its high-quality photovoltaic modules, ET Solar delivers cost-effective solar solutions suitable for both residential and commercial installations. With a focus on sustainability and innovation, ET Solar’s panels are tested to withstand Australia’s diverse weather conditions, offering homeowners and businesses a dependable way to switch to renewable energy. Positive user reviews highlight their consistent performance and durability, making ET Solar a trusted choice for anyone looking to invest in clean, reliable solar power.
ET Solar, officially known as Jiankai Sunshine New Energy Technology (formerly Zhongsheng Sunshine New Energy Technology), began its journey in 2005. Headquartered in Nanjing, China, the company operates mainly as a solar panel manufacturer and is owned by the Chinese government. With a workforce of more than 3,000 employees and an annual production capacity of around 1.7GW, ET Solar is considered a mid-sized solar manufacturer within China’s growing solar industry. One of the company’s strengths lies in its vertically integrated production process — meaning every stage of panel manufacturing, from raw materials to finished product, happens in-house. This approach gives ET Solar tighter control over product quality and reduces dependence on external suppliers.
In Australia, ET Solar panels reach the market through One Stop Warehouse, which handles local distribution. However, the company currently does not maintain an Australian office, local staff, or a dedicated Australian website.
At present, around 40 ET Solar panels are approved by the Clean Energy Council (CEC) under the name ET Solar New Energy Co. Ltd, qualifying them for Australia’s Small-scale Renewable Energy Scheme (SRES) — the government’s home solar rebate program. However, as of now, only the following three ET Solar panel models are commonly available in the Australian market:
The ETM380-72H model comes with 72 monocrystalline solar cells, known for their higher efficiency compared to polycrystalline panels. With a rated module efficiency of 19.6%, it performs on par with most modern solar technologies. One of its standout advantages is the high voltage capacity of 1500VDC, allowing more panels to be connected in each string — ideal for maximising system efficiency. Depending on the variant, this model offers a power output range of 360W to 385W.
The ETP340-72H also features 72 solar cells, but uses polycrystalline technology. This type of panel is generally more affordable, though slightly less efficient than monocrystalline ones. It delivers a module efficiency of 17.5%, which is on the lower end compared to most panels available today. A practical benefit of this model is its anti-reflective coating, which helps reduce dust accumulation and allows rainwater to naturally clean the surface. Power output ranges from 340W to 345W, depending on the specific variant.
The ETM400-144BL belongs to ET Solar’s high-performance range. It includes 144 monocrystalline half-cut solar cells, a design that has become standard in the industry due to its ability to boost efficiency without increasing panel size. With dimensions of roughly 2m x 1m, this model is best suited for commercial installations. It offers a rated efficiency of 19.9%, positioning it slightly above average in its category. Thanks to its parallel circuit design and half-cut cell layout, the Elite Plus also has enhanced shading tolerance. The panel provides a power output range of 400W to 410W, depending on the model.
When it comes to warranties, ET Solar offers both product and performance protection — two key factors that determine the long-term reliability of your solar panels.
ET Solar panels include a 10-year product warranty, covering manufacturing defects or faults that could cause the panel to fail or underperform. This duration is fairly standard across the industry and represents the minimum benchmark expected from most reputable solar brands.
Alongside product coverage, ET Solar provides a 25-year performance warranty. This guarantee ensures your panels will still deliver a consistent level of output throughout their lifespan.
Polycrystalline modules: 80.7% of rated power after 25 years
Monocrystalline modules: 80.68% of rated power after 25 years
While this is in line with market standards, it doesn’t exceed them — meaning ET Solar sits comfortably within the average range for warranty performance.
One concern for Australian buyers is that ET Solar does not currently have a local office, support staff, or Australian website. This can make the warranty claim process a bit more complicated. In most cases, you would need to contact your installer or wholesaler, who would then coordinate with ET Solar’s Chinese head office on your behalf.

At this time, we would not recommend purchasing ET Solar panels until the company sets up an Australian office and a local warranty claim process. With many solar installers going out of business over the past decade, it’s crucial to have direct recourse with the manufacturer if any issues arise. While ET Solar panels are efficient and well-built, there are plenty of other Chinese solar brands with a local presence, such as Trina, Jinko, or Suntech, that offer similar performance without the added risk
Solar industry experts have also spoken highly of ET Solar, particularly for its blend of innovation and dependable output.
