Import 310 Watt Solar Panel — Buy in wholesale FOB from Supplier in China

The SYP310S is a 310 Wp polycrystalline photovoltaic module built on a 72-cell layout using 156 mm x 156 mm silicon cells. Under Standard Test Conditions (STC: 1000 W/m² irradiance, 25°C cell temperature, AM1.5 spectrum), it delivers a maximum power output of 310 W with a voltage at maximum power (Vmp) of 37.94 V and current at maximum power (Imp) of 8.18 A. Open-circuit voltage (Voc) reaches 45.07 V, with short-circuit current (Isc) of 8.72 A. The module tolerates a power variance of ±3% and carries a temperature coefficient for Pmax of -0.44% per degree Celsius, a critical figure for yield calculations in warmer climates.

The panel employs a 5-busbar cell architecture, which reduces resistive losses and improves the temperature coefficient compared to older 3-busbar or 4-busbar designs. Its front glass and surface texturing enhance diffuse-light capture, supporting energy yield during overcast mornings or high-humidity conditions typical of subtropical installations. The anodised aluminium frame encloses the laminate in dimensions of 1956 x 992 x 35 mm, with a total mass of 21.8 kg per module. The junction box carries an IP65 ingress-protection rating, and the overall construction is certified to withstand wind loads of 2400 Pascals and snow loads of 5400 Pascals. Potential Induced Degradation (PID) resistance is verified under 85°C/85% relative humidity for 96 hours, a standard accelerated stress test for crystalline silicon modules.

Target buyers include EPC contractors, commercial rooftop developers, and agricultural or fishery hybrid project operators seeking 300 Wp-class polycrystalline arrays. The 72-cell format suits ground-mount and large tilt-roof configurations where higher Voc strings reduce BOS cabling costs. Importers should note that the supplier lists a 25-year linear power warranty, though the exact degradation rate and claims process should be clarified directly. Packaging, pallet quantities, and Incoterms are not stated in the source material and require confirmation with Xinchang Jinhe New Energy before contract negotiation.

Xinchang Jinhe New Energy Co., Ltd. is located at No. 533 Xiashiyan, Xinchang, Zhejiang Province, postal code 312500, in eastern China. The supplier is classified at the Harbor trust tier on this platform, and at the time of listing review shows a 0.00% response rate with an average response time of zero hours, indicating no inbound buyer engagement has been recorded or the metric has not yet populated. No verified third-party audit status, ISO certification numbers, or factory inspection reports are disclosed in the source material.

The company describes itself as serving markets across Europe, the Americas, and Asia, though no named clients, project references, or annual shipment volumes are provided. Its product range centres on polycrystalline modules in the 300-330 Wp band with TUV and IP67 references in older collateral, though buyers should request current IEC 61215 and IEC 61730 test reports directly. The profile does not state founding year, employee count, production capacity in MW per annum, or vertical integration (cell vs. module-only manufacturing). All commercial terms, including MOQ, lead time, Incoterms, and payment structure, must be negotiated directly with the supplier.
