The ASTRO N7 Pro is a high-performance n-type PV module launched by Astronergy in 2026. Built on the latest TOPCon 5.0+ cell technology and integrating quarter-cut design and ZBB technology, it delivers high power, high efficiency, high reliability, high bifaciality, low degradation, reduced hot spot risk, and an excellent temperature coefficient. The module achieves a maximum power output of 670W and a peak conversion efficiency of 24.8%.

The ASTRO N7 Pro is primarily designed for utility-scale power plants and commercial & industrial (C&I) distributed PV projects.

The ASTRO N7 Pro delivers a power output of 670W and a peak conversion efficiency of 24.8%, offering higher energy density. It integrates multiple advanced technologies to achieve a bifaciality of up to 85±5%, enhancing rear-side power gain. Its improved temperature coefficient of -0.26%/°C ensures lower power loss under identical temperature conditions, resulting in higher power generation per watt. The module also provides excellent shading tolerance, achieving a power gain of over 20% under partial shading and reducing hot spot temperature by 30°C. Additionally, it offers superior low-irradiance performance, with a gain of up to 3.4%, delivering a clear advantage in energy yield.

The ASTRO N7 Pro has received the full suite of TÜV Rheinland certifications and passed all IEC 61215/61730 aging tests. It is the first quarter-cut PV module to be awarded TÜV Rheinland certification. Its key performance metrics have been validated through multiple rigorous tests, confirming its high reliability.

Astronergy’s current product portfolio includes: ASTRO N8 for utility-scale power stations across various scenarios; ASTRO N7 Pro, a high-efficiency module for utility-scale and C&I distributed applications; ASTRO N7 2.0 for multiple scenarios; and ASTRO N7s 2.0 for the high-end residential market. In addition, Astronergy offers tailored solar solutions for specialized applications such as desert and offshore PV projects.

The ASTRO N7 Pro incorporates TOPCon 5.0+ cell technology, quarter-cut design, ZBB technology, and high-density encapsulation.

TOPCon 5.0+ builds on Astronergy’s TOPCon cell platform by integrating advanced technologies including ASP, PF, SNOP, emitter passivation optimization, and H passivation. This enables multidimensional breakthroughs in passivation effect, light capture, and bifacial performance. Compared to TOPCon 4.0, cell efficiency is increased by 0.7%+.

The quarter-cut design of the ASTRO N7 Pro reduces internal current, minimizing resistive power loss. Combined with non-destructive cutting and ASP (Astronergy Side Passivation) technology, it effectively reduces cutting losses, boosting module power by 25W. Additionally, the quarter-cut layout significantly lowers peak hot spot temperature, reducing hot spot-induced power loss, enhancing module reliability and system safety, and improving power generation per watt.

ASTRONERGY takes out insurance through Ariel Re every year, and the third-party insurance company can act as the ultimate guarantor of the customer’s rights and interests.

Inspect the appearance of the solar panels, test the module voltage and thermal imaging. And contact the manufacturer in a timely manner.

Contact the public email of after-sales service within the warranty period or get in touch with the salesperson at that time and provide the purchase invoice at that time.

First of all, the prerequisite is that the customer should ensure that their solar panels are installed, used and maintained in accordance with the provisions of the ASTRNERGY installation manual and are not included in the “Exceptions” of the warranty documents.
Secondly, the defect of the product needs to be confirmed as being caused by the substandard design, materials and production quality of ASTRONERGY, which has led to a significant negative abnormality in the power generation function.
We hope you will read our warranty documents carefully to guide the handling of your issues.

We could offer a 30-year product warranty and a 30-year performance warranty to fully meet your needs.
