Import 6'' Poly-Crystalline Solar Cell Taiwan Brand — Buy in Bulk from Supplier in China

The 6-inch poly-crystalline solar cell offered by Topsky Electronics Technology is a Taiwan-branded module designed for integration into photovoltaic panels. It features precision-sorted efficiency grades and color uniformity controls to ensure consistent performance in varied lighting conditions. Each cell is engineered for durability, with built-in reverse current protection to mitigate damage from shading or system faults.

Constructed from poly-crystalline silicon, the cell delivers a balance of cost efficiency and energy conversion typical of this material class. Industry standards for such cells include dimensional tolerances of ±0.5 mm, with typical thickness ranges between 180-220 micrometers. The front grid is usually silver-pasted for conductivity, while the back surface field layer enhances electron collection. These cells are commonly used in modules with standard 156 mm x 156 mm form factors, though this listing specifies a 6-inch variant.

Primary buyers include solar panel manufacturers and system integrators sourcing components for residential, commercial, or utility-scale projects. The cells are suited for grid-tied and off-grid applications where reliability under partial shading is a priority. Trade terms such as FOB or CIF are negotiable, with packaging typically designed to prevent micro-cracks during transit. Buyers should confirm the exact efficiency bin and certification status, as these vary by production batch.

Topsky Electronics Technology (HK) Co., Ltd. is based in Shenzhen, Guangdong Province, with its registered address at 494 Donghuan Road, Shajing Town, Baoan District. The company operates as an importer of electronic components, including photovoltaic cells, and holds a 'harbor' trust tier on the platform, indicating a verified operational presence. Response metrics are currently unrecorded, with no available data on response rate or average reply time.

The supplier specializes in the distribution of solar energy products, positioning itself as a link between manufacturers and downstream buyers. Its profile does not state certifications, production capacity, or client references, so these details must be requested directly. The focus appears to be on providing access to branded components, such as the Taiwan-origin poly-crystalline cells listed here, rather than in-house manufacturing.
