Send your PV module project details to the right Longi team

Use this page for module quotes, datasheet requests, regional installer support, warranty documentation, distributor coordination, and project timing questions. The more specific the inquiry, the faster Longi can route it to sales engineering, channel support, or the warranty desk.

A useful Longi inquiry usually includes the project country, site type, target DC capacity, preferred module wattage, construction window, certification requirements, and whether you are buying as an EPC, developer, distributor, installer, or asset owner. If you are replacing an existing module, include the original series, frame size, connector notes, and photos of the nameplate. If you are planning a new site, include roof type, tracker model, inverter brand, grid connection schedule, and any lender or insurer documentation needs.

Longi does not treat every contact request the same way. A residential installer may need stock availability and homeowner handover documents. A utility developer may need bifacial assumptions, pallet planning, warranty language, and bankability references. A distributor may need recurring supply coordination and regional escalation contacts. The form below helps collect enough context to make the first response practical.
