Import 250w Poly Solar Panel With Competitive Price — Buy in Bulk from Supplier in China

This polycrystalline photovoltaic module from Changzhou Great Solar Technology Co., Ltd delivers a 250W peak power output under standard test conditions of 1000 W/m² irradiance and 25°C cell temperature. The panel uses multi-crystalline silicon cells arranged in a standard 60-cell layout, a configuration widely adopted for residential rooftop and small commercial installations where cost per watt and established supply chains matter. Changzhou, located in Jiangsu Province, sits at the heart of China's solar manufacturing corridor, giving this supplier proximity to cell, glass, and frame material networks.

Polycrystalline technology in the 250W class typically achieves module efficiencies in the 15-17% range, with a temperature coefficient of power around -0.4% to -0.5% per degree Celsius above 25°C. The front surface uses tempered solar glass with anti-reflective coating, while the backsheet provides electrical insulation and moisture protection. Anodised aluminium frames of standard 30-35mm depth provide structural rigidity for wind and snow loads, with drainage holes to prevent frame corrosion from standing water.

Buyers range from solar EPC contractors assembling residential arrays to distributors serving off-grid rural electrification projects. The 250W format suits 12V or 24V battery charging with appropriate charge controllers, or string inverter configurations for grid-tied systems. Changzhou Great Solar Technology Co., Ltd should be asked to confirm cell efficiency, frame dimensions, weight, and whether the quoted power is nominal or guaranteed minimum. Buyers should also verify that the junction box carries IP65 or better rating and that cables and connectors are included.

Changzhou Great Solar Technology Co., Ltd is based at No.2 Tianshan Road, New District, Changzhou, Jiangsu Province, China. This location places the company within the Yangtze River Delta, a region with dense concentrations of photovoltaic manufacturing, glass production, and aluminium extrusion facilities. The supplier holds a harbour trust tier and imported supplier tier on this platform, with a response rate currently displayed as 0.00 and zero recorded average response hours. Buyers should interpret these signals as indicating limited platform-tracked engagement rather than a verdict on the company's trading capacity.

The supplier profile does not disclose founding year, annual capacity, factory certifications, or reference installations. No headcount, revenue figure, or client list is provided, and none should be invented. What the listing does state is a specific product (250W poly solar panel) with a defined power class. Prospective buyers should request Changzhou Great Solar Technology Co., Ltd's full datasheet, IEC 61215 and IEC 61730 test reports, and evidence of production-line quality control. A factory audit or third-party inspection before first shipment is advisable given the absence of verified buyer feedback.
