JinkoSolar Launches 670 W TOPCon Solar Module With 24.8% Efficiency

Wedoany.com Report-Sept. 6, Chinese solar module manufacturer JinkoSolar has introduced its latest product, the Tiger Neo 3.0, designed with tunnel oxide passivated contact (TOPCon) technology. The company described the new module as the “world's most powerful solar panel,” highlighting its performance specifications and enhanced efficiency.

The Tiger Neo 3.0 delivers 650–670 W of front-side power and features an 85% bifaciality factor. According to the manufacturer, this allows for an additional 553–570 W of rear-side power output. JinkoSolar noted: “The Tiger Neo 3.0 is the world’s longest working-hour panel built for utility-scale, DG, and rooftop solar systems. It has 30 W more power than conventional TOPCon, also has 10–15% higher bifacility and an approximately 10%–20% yield gain than back-contact panels under low light conditions, for instance 200W/m2.”

The panel’s dimensions are 2,396 mm × 1,134 mm × 30 mm, with a weight of 32.5 kg. Its power conversion efficiency is rated between 24.06% and 24.80%. The temperature coefficient is -0.26% per degree Celsius, ensuring improved performance in high-temperature conditions.

Electrical specifications include an open-circuit voltage ranging from 50.26 V to 50.98 V and a short-circuit current between 15.98 A and 16.22 A. The panel is engineered to operate in ambient temperatures from -40 °C to 70 °C. Its maximum system voltage is 1,500 V.

The design incorporates an anodized aluminum frame and 2.0 mm tempered glass with an anti-reflection coating, enhancing durability and efficiency. The junction box is rated IP-68, offering strong resistance to dust and water, suitable for challenging environments.

JinkoSolar is providing a 12-year product warranty and a 30-year power output guarantee with the Tiger Neo 3.0. The annual linear degradation rate is specified at 0.35%, with a first-year power loss of 1%. By the end of the 30-year period, the module is guaranteed to deliver at least 88.85% of its nominal power output.

The company emphasized that the new module has been designed for a wide range of applications, from utility-scale solar farms to distributed generation and rooftop systems. With its higher efficiency, extended durability, and improved energy yield under low-light conditions, the Tiger Neo 3.0 represents a further step in advancing solar technology performance.

By combining TOPCon design with enhanced bifacial performance, JinkoSolar aims to deliver a reliable and long-lasting module tailored for large-scale adoption in both residential and commercial solar markets. The introduction of the Tiger Neo 3.0 highlights the company’s continued focus on innovation and its role in developing next-generation photovoltaic solutions.
