Product Manufacturing Process

According to authoritative sources, the manufacturing process for high-efficiency photovoltaic modules like the ASTRO N7s involves several key steps. Firstly, high-purity silicon is extracted and processed to create mono-crystalline silicon wafers. These wafers are then subjected to the Passivated Emitter and Rear Cell (PERC) technology to increase their efficiency. The n-type TOPCon (Tunnel Oxide Passivated Contact) cells undergo further enhancement to reduce recombination and improve overall performance.

The wafers are then interconnected using Zero-busbar technology, which eliminates the need for metal ribbons, reducing shading and enhancing light capture. The modules are laminated between layers of tempered glass and encapsulated to protect against environmental factors. Finally, they undergo rigorous testing for durability and performance before being packaged for distribution.

Product Application Scenarios

Based on industry research, rooftop photovoltaic systems are increasingly being adopted across various sectors due to their versatility and efficiency. Residential applications benefit from the ASTRO N7s series due to its high efficiency and sleek design, which blends seamlessly with modern rooftops. Commercial establishments, such as shopping malls and office buildings, also capitalize on the power density offered by these modules to maximize their energy generation within limited roof space.

Balconies and other smaller rooftop scenarios can leverage the compact size and high output of these panels, ensuring optimal space usage. The durability and performance consistency of the ASTRO N7s series make it suitable for diverse climatic conditions, thereby providing reliable renewable energy solutions globally.
