Import 50w Solar Panel Cell Power Energy Mono Modular — Buy in wholesale FOB from Supplier in China

The Zonergy Co. Ltd SP050M-32 is a 50w monocrystalline solar panel built on PERC cell architecture, manufactured in Guangdong, China, with the corporate headquarters in Zigong, Sichuan province. This module uses 182mm x 182mm half-cut monocrystalline PERC cells arranged in a 2x16 configuration, producing a panel efficiency of 18.60% within compact dimensions of 670 x 400 x 25mm. The unit weighs 3.80kg and is framed in anodized aluminum alloy, with a 3.2mm high-permeability coated tempered glass front. Mechanical loading certification covers 5400Pa front and 2400Pa rear snow/wind loads, and the junction box carries IP67 protection with bypass diodes and an MC4-compatible connector.

The PERC (Passivated Emitter and Rear Cell) structure reduces rear recombination and improves current collection compared to standard aluminum back surface field cells, yielding better low-light response and temperature performance. The 182mm cell format, now a mainstream standard in utility-scale modules, provides larger active area per cell and reduced resistive losses from shorter current paths in the half-cut design. The 3.2mm glass with anti-reflective coating enhances light transmission, while the anodized aluminum frame provides structural rigidity and corrosion resistance. The IP67 junction box with bypass diodes protects against hot-spot damage when partial shading occurs, a critical reliability feature for distributed installations.

Target applications include commercial distributed photovoltaic systems, residential balcony or small rooftop arrays, and integration into Zonergy's PV-plus-storage system designs alongside the company's inverters and lithium battery modules. The compact 670mm x 400mm form factor suits space-limited installations where standard 60-cell or 72-cell modules are too large. Buyers should confirm whether this 50w model is stocked for standalone sale or primarily offered as part of Zonergy's integrated system packages, as the source description emphasizes solution designs over component-level availability. Warranty terms are stated at 10 years for this product, though power output warranty degradation terms require clarification.

Zonergy Co. Ltd is headquartered at No. 19, Donghuan Road, Bancang Industrial Park, Yantan District, Zigong, Sichuan province, China, postal code 643000, with manufacturing referenced in Guangdong province for this panel line. The company holds harbor trust tier status with a 0.00% platform response rate and zero recorded average response hours, indicating that direct outreach outside the platform will likely be necessary for timely communication. The source description positions Zonergy as a vertically integrated solution provider rather than a component-only manufacturer.

The company manufactures solar panels, energy storage inverters, lithium battery modules, and WiFi monitoring devices, offering three integrated system designs: PV-plus-storage new installations, AC-coupled battery retrofits to existing grid-tied systems, and grid-connected distributed photovoltaic systems. Factory-level certifications listed include ISO9001:2008, ISO14001:2004, and OHSAS18001, with product certifications IEC61215, IEC61730, and UL1703 cited. No information is provided about annual production capacity, factory floor space, employee count, years in operation, or specific reference projects. Buyers should independently verify current certification status, as some standards referenced may have been updated since initial issuance.
