Import 15kw Home Grid-Tied Solar Power System — Buy in wholesale FOB from Supplier in China

This 15kW grid-tied solar power system from Zhejiang Dongshuo New Energy Co. Ltd. is a complete kit designed for residential installations, comprising 55 polycrystalline solar panels each rated at 275W. The system includes a 15kW grid-tied inverter compatible with AC 220-240V or 380-410V at 50/60Hz, featuring multi-MPPT tracking to optimise power output across different string configurations. It is supplied with 200 metres of single-core PV cable (4mm² and 10mm²), 10 pairs of MC4 connectors, a WiFi-based monitoring system (Shine model), and a bag containing five types of PV installation tools.

The solar panels carry TUV, UL, JET, and CQC certifications and are backed by a 12-year product warranty alongside a 30-year linear power output warranty, which is a standard tier for polycrystalline modules in this class. The system requires approximately 120 square metres of roof or ground space for mounting, with pitched roof, flat roof, and ground-mount support options included. Polycrystalline cells typically achieve module efficiencies in the 17-18% range, though exact performance depends on local irradiance and tilt angle. The inverter's multi-MPPT design allows it to handle strings at different orientations, which is useful for roofs with varied pitch directions.

This configuration suits homeowners or small commercial properties aiming to offset grid electricity consumption through net metering arrangements. Buyers in markets with feed-in tariffs or net billing policies can use the real-time WiFi monitoring to track generation and self-consumption. The listing notes add-on options for battery storage, which would shift the system towards hybrid capability, though battery specifications and pricing are not detailed and should be confirmed directly with the supplier. Zhejiang Dongshuo New Energy Co. Ltd. is based in Hangzhou, Zhejiang, China, and lifetime technical support is stated as part of the package.

Zhejiang Dongshuo New Energy Co. Ltd. is based in Hangzhou, Zhejiang Province, China, with a registered address at Room 411, Tower 1, Caihejiaye Building. The supplier is listed with a 'harbor' trust tier on the platform, though the current response rate shows 0% and average response time is not recorded, which means prospective buyers should allow for potential delays in communication and may wish to initiate contact well in advance of any project timeline.

The listing presents this supplier as a provider of complete solar power system kits rather than a single-component manufacturer. The product page details a full component list with specific quantities, certifications, and warranty terms, but does not disclose the company's manufacturing scale, years in operation, export history, or client portfolio. Buyers should request verifiable documentation such as business registration certificates, export licences, and factory audit reports before committing to a bulk order.
