Astronergy continues to innovate with the launch of the All Black and Small solar modules from the ASTRO N7s series. Equipped with ZBB (Zero Busbar) and TF (Tiling Film) technology, these modules combine sophisticated aesthetics, high performance, and durability. However, like any technological solution, they have advantages and disadvantages that consumers and integrators should consider.

Advantages of the ASTRO N7s All Black and Small modules

1. Improved efficiency

Thanks to ZBB-TF technology and TOPCon 4.0 cells, the elimination of conventional busbars and the reduction of soldering temperature below 150°C minimize thermal stresses and reduce hidden microcracks. This contributes to higher module efficiency and durability, reaching a maximum efficiency of up to 23%.

2. Elegant and discreet design

The All Black modules offer superior aesthetics, making them ideal for residential and commercial installations that prioritize visual harmony with roofs and facades.

3. Ease of installation and handling

The compact format of the small modules, along with their weight of only 21.5 kg, makes transportation and installation easier. This feature has been a preference among installers in the European market, where these modules have seen greater adoption.

4. Optimized performance in low irradiance

Thanks to innovation in the interconnection of cells, the modules maintain good performance even in low light conditions, maximizing energy generation throughout the day.

5. Low power degradation

The modules show only 1.0% power degradation in the first year and an annual rate of up to 0.4% in the following years, ensuring 87.4% efficiency at the end of 30 years.

6. Extended warranty

The ASTRO N7s modules come with a 25-year product warranty, covering almost their entire lifespan, and a 30-year linear power warranty. This reflects Astronergy’s confidence in the quality, reliability, and durability of its products.

7. TÜV Rheinland certification and technological innovation

The ASTRO N7s ZBB n-type TOPCon modules have certification from the renowned TÜV Rheinland, ensuring high standards of quality, safety, and performance. The combination of TF technology and high-density encapsulation in the 48 TOPCon cells eliminates gaps between cells, maximizing light capture and reducing energy losses. This structural improvement significantly increases the efficiency of each unit, making these modules an ideal option for commercial, industrial, and residential solar systems seeking maximum performance and reliability.

8. Proven high reliability in extreme conditions

Recently, Astronergy’s ASTRO N7s ZBB-TOPCon modules successfully passed rigorous tests conducted by TÜV NORD, obtaining three key certifications: the world’s first UVID-Free certificate, IEC TS 63126 Extended High Temperature (Level 2) certification, and IEC 62892 Extended Thermal Cycling (TC) certification. These recognitions highlight the exceptional reliability of Astronergy’s ZBB-TOPCon modules, ensuring their high performance even in the most extreme environmental conditions.

Disadvantages of the ASTRO N7s All Black and Small modules

1. Potentially higher initial cost

Due to technological innovations and premium design, the All Black modules may have a higher initial cost compared to conventional alternatives.

2. Increased heating of All Black modules

The completely black coating may generate slightly higher operating temperatures, which could impact the module’s efficiency in very hot environments.

3. Lower unit power in small modules

Despite flexibility in installation, the smaller modules have lower unit power, making them ideal for residential projects and, in some cases, C&I projects.

Market and trends

In the Latin American market, these modules have not yet seen significant demand, but in the European market, they have been widely adopted, especially in projects that prioritize efficiency and aesthetics.

The ASTRO N7s All Black and Small modules from Astronergy represent an excellent option for those seeking an efficient, modern, and visually sophisticated photovoltaic system. With ZBB-TF technology and advanced TOPCon 4.0 technology, the brand reaffirms its commitment to innovation and quality. However, the investment decision should consider both the performance and aesthetic benefits, as well as the potential challenges related to cost and heating.
