Buyer's Digest

Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Solar Panels And Modules. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

The LONGI Hi-MO5m is a monocrystalline solar module offered across a 525–550 W power range. The listed configuration uses 144 , with a stated weight of 27.2 kg.

Its mechanical construction includes a 35 mm anodized aluminum-alloy frame, 3.2 mm front glass, an IP68 junction box with three bypass diodes, and MC4-compatible connectors.

Electrical and operating data provided for the module include a maximum system voltage of 1500 V, a 20 A maximum series-fuse rating, and a non-negative power tolerance of 0 to +5 W. The stated operating-temperature range is -40°C to +85°C.

Listed temperature coefficients are -0.35%/°C for maximum power, -0.27%/°C for open-circuit voltage, and 0.048%/°C for short-circuit current.

Nominal module operating temperature is stated as 42 ± 3°C, while another product section lists 41 ± 3°C;buyers should resolve this difference against the exact datasheet supplied with the ordered wattage.

The listing states 21.5% panel efficiency, a 25-year warranty, Class A application classification, and Type 3 under UL 1703 or Class C under IEC 61730 for module fire performance. EST, ISO, CE, and TUV certifications are also listed.

Certification documents, applicable standard editions, certificate holders, model coverage, warranty terms, and regional acceptance should all be verified before specification or purchase. Several details require confirmation because the supplied information contains mixed terminology.

The module is described as monofacial in one section, while a 70% power-bifaciality value and rear-side shading references appear elsewhere. The front glass is also described both as heat-strengthened glass and as coated tempered glass.

Buyers should therefore request the model-specific technical datasheet, construction drawing, electrical characteristic table, and warranty document for the precise 525 W, 530 W, 535 W, 540 W, or 550 W variant being considered.

For logistics planning, the stated packing quantities are 31 modules per pallet and 682 modules per 40-foot high-cube container. Transport packaging is listed as carton or wooden box.

Confirm final pallet dimensions, gross weight, container loading plan, connector and cable configuration, mounting-hole locations, delivery schedule, customization scope, and applicable commercial terms before placing an order.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
