Wholesale & Project Support
Send your required quantity and destination country or port. We will confirm the module version, availability, packing plan, delivery time and EXW or FOB price. Suitable inverters, batteries and mounting accessories can be quoted separately for a complete equipment proposal.
Check inverter MPPT voltage, input current and cold-weather open-circuit voltage before finalizing the string design.
Frequently Asked Questions
Is this model bifacial?
Yes. Rear-side output varies with site reflectivity, mounting and shading. A fixed rear-side gain is not guaranteed.
Does the panel always generate 660W?
660W is its STC rating. Actual output changes with sunlight, temperature, orientation and system losses.
What warranty is available?
LONGi lists 15-year product and 30-year performance warranties for this series. Applicable terms and regional eligibility are confirmed for the supplied version.
Can you quote a complete solar system?
Yes. Tell us the project country, target system size and whether battery backup is required.
What is needed for a quotation?
Please provide quantity and destination. If you need system matching, include the inverter model or project requirements.
