Import 305w Mono Solar Panel From Hetech Energy — Buy in wholesale FOB from Supplier in China

The HT-M305W-72P is a 305 W monocrystalline photovoltaic module built on a 72-cell layout, with peak power tolerance of 0 to +3%. At standard test conditions it delivers an optimum operating voltage of 36.8 V and optimum operating current of 8.28 A, while open-circuit voltage reaches 44.5 V and short-circuit current 9.11 A. The module is rated for maximum system voltage of DC 1000 V and carries a 5-year product defect warranty alongside a 25-year linear power output warranty guaranteeing 90% output at 10 years and 80% at 25 years.

Each cell measures 156 x 156 mm in a 6 x 12 series-parallel arrangement, laminated behind 4.0 mm tempered glass with an anodized aluminum alloy frame. The junction box achieves IP67 or IP65 ingress protection, paired with MC4 connectors for field wiring. Module dimensions are 1956 x 992 x 45 mm with a total weight of 27 kg, a standard size and mass for 72-cell utility-scale panels that allows compatibility with most fixed-tilt and single-axis tracking racking systems. The monocrystalline silicon construction typically offers higher cell efficiency and better low-light performance than polycrystalline equivalents in the same power class.

This panel suits utility-scale solar farms, commercial rooftop installations, and industrial distributed generation projects where DC 1000 V system architecture is standard. B2B buyers should confirm with Hetech Energy Co., Ltd whether pallets ship from Zhengzhou or a coastal port, and verify Incoterms, as the listing does not state FOB, CIF, or EXW terms. Importers should also request IEC 61215 and IEC 61730 certification documents, plus PID and salt-mist test reports, since these are standard requirements for bankable projects but are not explicitly confirmed in the source data.

Hetech Energy Co., Ltd is registered at No.92 Huayuan Road, Zhengzhou, 450000, China, placing its headquarters in Henan Province's capital, an inland logistics hub with rail connections to coastal ports. The supplier carries a harbor trust tier on the marketplace, which indicates a baseline verification level, though its response rate is recorded as 0.00% with an average response time of 0 hours, suggesting either a new listing or inactive profile management. Buyers should treat communication reliability as an unverified variable and initiate direct contact early in the sourcing process.

The company lists a single 305 W monocrystalline panel with detailed electrical and mechanical parameters, which demonstrates product-level technical competence, but its profile does not disclose manufacturing capacity, annual output, number of production lines, or in-house cell versus module assembly scope. No ISO 9001, ISO 14001, or IEC certification numbers are provided in the source data. Importers should request factory audit reports, EL images, and flash test data before committing to volume orders, and verify whether Hetech Energy manufactures cells in-house or sources them from tier-1 cell suppliers.
