Import 300w Mono/Poly Solar Panel — Buy in wholesale FOB from Supplier in China

This 300W photovoltaic module from YY Solar uses polycrystalline silicon cells measuring 156 mm by 156 mm, arranged in a 6 by 12 series configuration for 72 cells total. The panel physical dimensions are 1960 mm by 990 mm by 35 mm, with a total weight of 25.5 kg. Electrical parameters include an open circuit voltage (Voc) of 44.8V to 45.2V, maximum power voltage (Vmp) of 35.8V to 36.1V, short circuit current (Isc) of 8.86A to 9.04A, and maximum power current (Imp) of 8.37A to 8.58A. Power tolerance is rated at ±3%, with a maximum system voltage of 1000V.

The 72-cell layout is a standard configuration for 300W-class modules targeting utility and commercial installations where higher voltage strings reduce balance-of-system costs. Polycrystalline cell technology offers a cost-effective manufacturing route compared to monocrystalline alternatives, with typical cell efficiencies in the 16-18% range for this format. The aluminum frame and tempered glass construction are standard for IEC 61215 certification compliance, though buyers should verify specific certification status with YY Solar directly. The 35 mm frame height accommodates standard mounting clamps and rail systems used in ground-mount and rooftop arrays.

Target buyers include EPC contractors, solar project developers, and renewable energy distributors serving utility-scale, commercial, and large residential markets. The 1000V system voltage rating suits string inverter architectures common in installations where DC cabling runs are substantial. Importers should confirm packaging configurations, pallet quantities, and whether modules ship with factory-installed bypass diodes and MC4-compatible connectors. Voltage and current specifications suggest compatibility with common 60-cell string inverter platforms when configured in appropriate series strings.

YY Solar is headquartered at No.306 Meiyou Road, Wuxi, Jiangsu Province, 214400, China. Wuxi is a recognised cluster for photovoltaic manufacturing in the Yangtze River Delta region, with established supply chains for silicon wafers, cells, and module assembly. The supplier holds a Harbor trust tier designation on the platform, indicating a baseline verification level. The response rate is reported at 0.00% with zero average response hours, which suggests either a new listing or limited active engagement through platform messaging channels.

The supplier profile does not disclose manufacturing capacity, annual output, number of employees, or specific certifications held. No client references, export markets, or years in operation are stated. Buyers should conduct direct due diligence to verify factory audit status, quality management systems (ISO 9001), and environmental compliance. The Wuxi location offers logistical advantages via Shanghai Port for sea freight exports, though this should be confirmed with YY Solar for specific shipping arrangements and export licensing.
