Import 5w Solar Panel(Ckpv-050w Solar Panel) — Buy in Bulk from Supplier in China

The CKPV-050W is a 5W photovoltaic module from Dongguan Superb-solar Co., Ltd., rated for low-power DC applications where compact dimensions and minimal weight are priorities. The panel uses crystalline silicon cells, either monocrystalline or polycrystalline, with a standard output voltage of 12V or 18V typical for this wattage class. The 5W rating places it in the small-module category used for trickle charging, portable lighting, and off-grid sensor power rather than grid-tied generation. Buyers should confirm with the supplier the exact cell type, open-circuit voltage, and short-circuit current, as these are not stated in the source material.

Module construction for a 5W panel of this type typically comprises tempered glass frontsheet, EVA encapsulant, crystalline silicon cell matrix, and a TPT or PET backsheet laminated in an aluminium frame. Junction box protection is usually IP65 rated for outdoor use, with bypass diodes to mitigate hot-spot risk during partial shading. Cell efficiency for this size and generation of module generally falls in the 17-20 percent range for monocrystalline and 15-17 percent for polycrystalline, though Dongguan Superb-solar Co., Ltd. should provide the specific efficiency figure and temperature coefficient for power.

Target buyers include solar system integrators, rural electrification project developers, marine electronics suppliers, and manufacturers of portable power stations or street lighting. The panel suits 12V battery charging, IoT device power, small DC fan or pump operation, and educational demonstration kits. Importers should verify whether the CKPV-050W carries IEC 61215 and IEC 61730 certification for crystalline modules, as these are standard requirements for most markets and insurance coverage. The source mentions ISO certification but does not specify which standard or certifying body.

Dongguan Superb-solar Co., Ltd. operates from Building 5, Guanghui Industrial Area, Dongcheng Technology Park, Dongguan 523127, Guangdong, China, situating it within one of China's major manufacturing hubs for electronics and renewable energy components. The supplier carries a harbour trust tier and imported supplier tier, with a response rate of 0.00 percent and zero recorded average response hours. This pattern indicates that communication metrics are either untracked or reflect minimal platform engagement, so buyers should conduct direct outreach via the provided contact channels to assess responsiveness and English-language technical support capability.

The company name suggests specialisation in solar products, though the source profile does not indicate factory ownership, production capacity, number of employees, or years in operation. No ISO certificate number, IEC test report references, or client project histories are present in the available data. The address references an industrial area rather than a dedicated solar park, which is common for Dongguan-based manufacturers that share facilities or operate as assembly houses. Buyers should request a factory profile or virtual audit to understand whether Dongguan Superb-solar Co., Ltd. manufactures cells in-house or sources them from tier-one cell producers, as this affects batch consistency and warranty backing.
