Longi project support for specification, procurement, and field handoff

Longi services are built for teams that need clear module documentation before purchasing and reliable coordination after pallets leave the warehouse. The process begins with project context: module power class, system voltage, roof or ground-mount constraints, destination market, and warranty expectations. From there, sales engineering can align recommended modules with certification requirements, packaging assumptions, and installation realities. This is not a generic quote queue. It is a disciplined support path for solar developers, EPC contractors, distributors, and installer networks that must control project risk over a 25-year asset life.

The same project may involve procurement, owner engineering, lender review, construction management, and local installers. Longi service content is therefore organized around the questions that travel between those roles: which module series fits the design, which certificates are relevant to the region, how many pallets are needed, what installation notes should be shared with the crew, and how warranty registration will be handled after commissioning.

Structured Specs

What the Longi support desk checks before recommendation

Mechanical fitFrame type, module dimensions, clamp zones, wind and snow loading context, roof access, tracker compatibility, and packaging limits.
Market complianceIEC 61215, IEC 61730, UL 61730, CE documentation, TUV testing references, and region-specific submittal expectations.
Commercial fitDelivery window, pallet count, distributor route, warranty documentation, serial traceability, and installer handover workflow.
Methodology

A numbered path from requirement to signed module supply

01

Project intake

Collect site location, array type, target capacity, delivery schedule, certification needs, and the commercial role of each buyer stakeholder.

02

Module matching

Compare standard, black-frame, high-output, and bifacial module options against the design envelope and bankability requirements.

03

Document pack

Prepare datasheets, warranty summaries, installation references, packaging notes, and compliance files for internal engineering review.

04

Installer handoff

Coordinate distributor or installer network communication so procurement decisions translate into clean field execution and warranty registration.

Bring us the project constraints. We will help narrow the PV module path.

Use the inquiry form to share drawings, wattage targets, or market requirements. Longi support will route the request to the appropriate regional team and respond with the documentation path that fits your stage of procurement.
