Product Manufacturing Process

The manufacturing process of high-efficiency solar panels like the ASTRO N7s involves several stages. First, the n-type mono-crystalline silicon wafers are produced using the Czochralski process, which grows high-purity silicon crystals. These wafers undergo a series of doping treatments to create the n-type semiconductor material. Next, TOPCon (Tunnel Oxide Passivated Contact) technology is applied, significantly enhancing the panel's efficiency by reducing electron recombination losses. The cells are then interconnected using Zero-busbar Tiling film technology, which ensures optimum conductivity and minimal resistance. Finally, these cells are encapsulated in protective layers of glass and laminate, assembled into modules, and thoroughly tested to meet stringent quality standards. Research indicates that this advanced process results in higher efficiency and durability compared to traditional panels (Source: Journal of Renewable and Sustainable Energy, 2022).

Product Application Scenarios

High-efficiency solar panels like the ASTRO N7s are versatile and find application in various scenarios. In residential settings, these panels are installed on rooftops, providing homeowners with sustainable energy solutions while reducing electricity bills. Commercial establishments such as offices and retail stores benefit from these panels by offsetting their operational energy costs and contributing to corporate sustainability goals. Balcony installations are gaining traction, especially in urban areas, where space is limited but the demand for renewable energy options is high. Research shows that incorporating bifacial technology, which captures sunlight from both sides, further enhances energy production in environments with reflective surfaces (Source: Energy and Buildings, 2023).
