Import A Grade Poly 80w Solar Panel — Buy in wholesale FOB from Supplier in China

The UNP-80A from Union Solar Energy Tech. Co., Ltd. is an 80 W polycrystalline solar module rated at A grade, built on 156 mm poly-crystalline cells with a peak power (Pmax) of 80 W and optimum power voltage (Vmp) of 17.6 V. Its electrical profile includes a short-circuit current (Isc) of 4.71 A and an optimum operating current (Imp) of 4.38 A, with an open-circuit voltage (Voc) of 22.1 V. The module weighs 5.9 kg and measures 780 x 670 x 30 mm, dimensions that suit compact off-grid and portable arrays where space is constrained. Each panel carries CE and TUV certification, and the factory holds ISO9001 registration, though buyers should request current certificate copies directly from the supplier.

The frame is aluminium (standard for this class), with tempered glass and EVA encapsulation typical of poly-crystalline construction. A grade classification here denotes cell efficiency and absence of visible defects, but industry practice varies; buyers should confirm whether the rating refers to cell binning or finished-module flash-test sorting. The 30 mm frame depth is standard for glass-backsheet modules in this power class. Union Solar offers OEM packaging design without charge, and has produced private-label units for brands including Mighty Mule, Power Tech, Premium Enjoy Solar and Westech, which indicates volume manufacturing capability rather than bespoke engineering.

Target applications include courtyard lighting, small home DC systems, street lighting, garden water pumps, marine and RV auxiliary power, and camping kits. The module is explicitly positioned for off-grid use, so importers should verify whether the supplier provides matching charge controllers or battery kits. The 25-year performance warranty is stated, yet the exact degradation curve and terms should be requested in writing before order confirmation. Typical MOQ, lead time and Incoterms are not disclosed in the listing; buyers must confirm these, plus available port of departure from Wuxi, Jiangsu.

Union Solar Energy Tech. Co., Ltd. operates from No.6 Tansuo Road in Wuxi City, Jiangsu Province, China, a region with dense photovoltaic manufacturing clustering. The supplier is listed at Harbor trust tier with a response rate of 0.00 and no recorded average response hours, which signals that direct communication channels may be slow or untested through the platform. ISO9001 certification is claimed, and the factory states OEM experience with more than 100 companies, though no client list or revenue figures are provided. The listing does not disclose production capacity, number of production lines, or year of establishment, so buyers should request a company profile or factory audit report before committing to volume orders.

Given the zero response rate, importers should expect to initiate contact through multiple channels (email, phone, trade-show meeting) and allow extra time for quotation turnaround. It is prudent to request a current Bill of Materials, cell supplier name, and flash-test report for the specific UNP-80A batch before payment. Third-party pre-shipment inspection (typically SGS or BV) is advisable for a first order, focusing on power output verification at STC, EL imaging for cell cracks, and frame grounding continuity. Confirm whether the 25-year warranty is backed by insurance or escrow, and obtain the English warranty document in advance.

Union Solar Energy Tech. Co., Ltd. is headquartered at No.6 Tansuo Road, Wuxi City, Jiangsu Province, China, a location within one of the country's principal photovoltaic manufacturing corridors. The company holds ISO9001 quality-management certification and states that it has provided OEM services to over 100 brands, including Mighty Mule, Power Tech, Premium Enjoy Solar and Westech. Its product range centres on off-grid polycrystalline solar panels, with the UNP-80A representing a compact entry in its catalogue. The listing does not indicate the year of establishment, registered capital, factory floor area, or number of employees, so these details must be requested directly.

The supplier's trust signals are limited: it carries a Harbor tier designation, but shows a 0.00 response rate and zero average response hours on the platform, which means buyers should not rely on instant messaging for urgent technical or commercial queries. No export licence number, social-compliance audit, or bank reference is displayed. Importers are advised to conduct a factory audit or video inspection, request references from recent German or European clients (given the anti-dumping reference in the source description), and verify that CE and TUV certificates cover the exact UNP-80A model and current production run before issuing a purchase order.
