Suntech in the Solar Panel Market: A Review

In this review, we dive into the evolution of Suntech, a former titan in the solar industry. 

Key Points

  • Suntech, established in 2001 in China, was a dominant player in the solar industry by the late 2000s. Despite facing financial challenges and defaulting, the company has since regained stability, though it hasn’t reclaimed its top market position.
  • The company produces a diverse range of panels, including both monofacial and bifacial options, catering to various applications.
  • As of early 2023, Suntech’s panels are competitively priced, ranging from $0.7 to $0.9 per watt before installation costs.
  • Efficiency is a strong point for Suntech, with their latest models achieving up to 22.5% efficiency.
  • Customer and employee feedback about Suntech is largely positive, despite some early challenges in the company’s history.
  • Warranty terms include a 12-year product warranty, with a 25-year performance warranty for monofacial modules and a 30-year guarantee for bifacial modules.

Suntech’s History in the Solar Market

Founded in 2001 in Wuxi, China by Dr. Shi Zhengrong, an alumnus of the University of New South Wales’ School of Photovoltaic and Renewable Energy Engineering, Suntech rapidly ascended to prominence under his leadership until 2013.

Suntech’s rise was rapid, securing its position as a leading force in the solar sector. Dr. Shi earned acclaim, including being named a “Hero of the Environment” by Time magazine in 2007 and gaining recognition as the world’s first ‘green billionaire’. By 2011, the company had captured the largest market share in the photovoltaic (PV) industry.

However, the early 2010s proved challenging for PV companies, with market oversaturation impacting many. Suntech faced its own difficulties, closing its Arizona plant in 2013 and grappling with a $541 million debt default, leading to Dr. Shi’s departure from his chairman role.

Yet, this was not the end of Suntech. The company continued producing solar panels and gradually regained stability. Although no longer at the forefront of the market, Suntech has stabilized and is known for producing quality products. We will take a closer look at their current offerings.

Advantages and Disadvantages of Suntech Solar Panels

Advantages of Suntech Panels

  • Affordable Pricing: One of the most notable aspects of Suntech panels is their cost-effectiveness, a common trait of Chinese-made PV modules.
  • High Efficiency: Suntech panels have an efficiency rate exceeding 22.5%, significantly surpassing the market average of 19-20%.
  • Positive Reviews: Despite some early challenges, Suntech has garnered mostly favorable reviews from customers. Additionally, employee feedback about the company is generally positive.

Disadvantages of Suntech Panels:

  • Availability in the US: Being a Chinese company, Suntech panels may sometimes be hard to get your hands on in the US market.
  • Standard Warranty Terms: Suntech offers a standard 12-year product warranty. While adequate, this warranty duration is not particularly exceptional compared to some competitors.

Suntech Solar Panels’ Pricing, Efficiency, and Warranties

Suntech specializes in producing monocrystalline solar panels suitable for various applications. Their range includes both monofacial and bifacial options. These panels incorporate modern technologies like half-cut cells, PERCs, and multi-busbar designs. However, they tend to lack distinctive features that set them apart.

Priced Competitively at $0.70-$0.90 per Watt

In 2023, Suntech’s solar panels are available in the U.S. market at a cost-effective rate of $0.70 to $0.90 per watt, excluding installation fees. This pricing is notably lower than that of North American-made panels.

Efficiency Rates Between 19%-22.5%

Suntech panels achieve efficiency levels of up to 22.5%, which is significantly above the market average. This high efficiency means you’ll need less space for your solar system.

Standard 12-Year Product Warranty, Extended Performance Warranty

Suntech offers a standard 12-year product warranty, typical for Chinese manufacturers. The warranty extends to 25 years for monofacial modules and 30 years for bifacial modules in terms of performance.
