Shine Bright or Fade Fast? (Review) – GWC Mag

In the sun-drenched landscape of Australia, where rooftop solar reigns supreme, choosing the right panels is a crucial decision. Enter LONGi, a rising star in the photovoltaic world, claiming a significant share of Australian rooftops. But are LONGi panels truly a shining example, or do they harbour shadows of doubt? Let’s dive into a fair review, exploring LONGi’s history, technology, and performance in the Australian context.

LONGi’s rise: A history of innovation

LONGi Solar was founded in 2000 as Xi’an LONGi Silicon Materials Corporation, focusing on developing and producing single crystal (mono) silicon wafers used in many major solar panels. 

LONGi has rapidly ascended to become a Tier 1 solar panel manufacturer, recognised for its cutting-edge technology and commitment to quality. They’ve broken world records for cell efficiency, boasting an impressive 22.43% conversion rate for mass-produced PERC cells. This translates to increased energy output from each panel, a significant advantage for Australian homeowners seeking to maximise their solar investment.

LONGi Solar’s vision is to be the world’s most valuable solar technology company and to make the best of solar energy to build a green world. The company has been recognised for its excellence and innovation by various awards and rankings, such as the Bloomberg Tier 1 ranking, the Fortune China 500 ranking, the PV ModuleTech Bankability AAA rating, and the Brand Finance Global 500 ranking.

Tech talk: Unveiling the LONGi advantage

So, what makes LONGi Solar panels stand out from the crowd? LONGi’s technological prowess manifests in several key areas:

• High-efficiency: LONGi Solar panels have achieved some of the highest conversion efficiencies in the industry, thanks to their advanced monocrystalline silicon technology. For example, the efficiency of the LONGi Hi-MO 4 series modules is up to 21%, but the efficiency of the LONGi Hi-MO 5 series modules is up to 21.9%. 
• Half-cut cell design: Dividing cells in half reduces internal resistance, minimising power loss and improving performance in hotter climates – particularly relevant for Australia’s blazing summers.
• Bifacial panels: These panels absorb sunlight from both sides, generating additional power from rooftop reflections. While still a niche, LONGi’s bifacial options offer the potential for maximising energy capture.
• High reliability: LONGi Solar panels are designed and tested to withstand harsh environmental conditions, such as extreme temperatures, humidity, wind, hail, and salt mist. 

LONGi Solar panels have passed various international certifications and standards, such as the International Electrotechnical Commission (IEC), Underwriters Laboratories (UL), Technischer Überwachungsverein (TÜV, which translates to Technical Inspection Association in English), and Clean Energy Council (CEC). LONGi Solar panels have also been named a Top Performer in PV Evolution Labs’ (PVEL) 2020 PV Module Reliability Scorecard, which assesses solar panel performance and durability via extensive testing.

• High quality: LONGi Solar panels are manufactured with strict quality control and assurance processes, from raw materials to finished products. LONGi Solar has a vertically integrated supply chain, producing silicon ingots, wafers, cells, and modules, ensuring consistency and traceability throughout the production process. LONGi Solar also has a global network of service and support teams and local offices and warehouses in Australia to provide timely and professional assistance to customers and partners.
• High value: LONGi Solar panels offer a competitive price-performance ratio, combining high efficiency, reliability, and quality with reasonable cost. The extensive warranty policy with LONGi Solar panels covers linear power output for 25 years and product defects for 12 years. Moreover, LONGi Solar panels have a low environmental impact, use less energy and materials to produce, and have a higher power generation and carbon reduction potential over their lifespan.

Warranty and reliability: Peace of mind down under

LONGi offers a 12-year product and 25-year performance warranty on its panels. This means they guarantee at least 83.1% (standard panels) and 84.8% (PERC panels) of the initial power output after 25 years. This surpasses the industry standard, offering Australians peace of mind and the assurance of long-term energy generation.

Cost-effectiveness: Balancing price and performance

LONGi panels fall within the mid-range price bracket compared to premium brands. This makes them an attractive option for budget-conscious Australians seeking good value for money. However, it’s crucial to remember that the cheapest option isn’t always the best. Investing in a slightly more expensive panel with higher efficiency can lead to significant long-term savings through increased energy production.

Shining a light on reviews

So, how do LONGi panels fare in the Australian context? Reviews paint a positive picture, with users praising their high efficiency, reliable performance, and competitive pricing. Independent testing by CHOICE, a leading consumer advocacy group, confirms these claims, placing LONGi panels among the top performers regarding efficiency and power output.

Beyond the glow: A balanced perspective

However, a fair review demands acknowledging potential drawbacks. Some users report slightly higher degradation rates than certain premium brands, though LONGi’s warranty guarantees a minimum of 83.1% power output after 25 years, exceeding industry standards. Additionally, their wide range of models can be overwhelming for some consumers, requiring careful comparison to find the perfect fit.

The verdict

LONGi Solar panels are a fair and attractive choice for Australian customers looking for high-performance, high-quality, and high-value solar products. LONGi Solar panels have a proven track record of delivering excellent results in various applications and environments and have received positive feedback and reviews from many satisfied customers.

A balanced beam of light

Ultimately, LONGi shines brightly in the Australian solar landscape, offering a reliable and efficient option for homeowners seeking to harness the power of the sun. Whether you choose LONGi or another brand, remember, the sun doesn’t care – the energy you capture truly matters.

A fair review for Aussie sunseekers: A bright future for LONGi in Australia?

Ultimately, LONGi panels offer a compelling proposition for Australian homeowners seeking reliable, efficient, cost-effective solar solutions. Their strengths, including high efficiency, solid warranties, and competitive pricing, make them a strong contender. However, potential drawbacks like slightly higher degradation and a diverse model range require careful consideration.

LONGi Panels are not the undisputed solar champions of Australia, but they hold their own against established players. LONGi Solar panels offer a compelling package for Australians seeking high efficiency, and reliability. 

Their impressive performance, temperature resistance, and industry-leading warranty make them a strong contender for Aussie rooftops. Their cutting-edge technology, impressive performance, and competitive pricing make them a viable option for homeowners seeking a smart solar investment. 

So, before you bask in the glow of a new solar system, take the time to compare LONGi with other brands and make an informed decision. Remember, the perfect panel for your Australian home is the one that shines brightest for your specific needs and budget.
