Are there hidden fees in shipping costs?

Full container shipments have no hidden fees. For LCL or CIF terms, charges may apply at the destination port. We recommend FOB or CIP terms to avoid uncertainty.

Can you provide DDP pricing or lower invoices for tariffs?

DDP is available but not cost-effective due to unknown local freight and tax policies. We can cooperate on invoice requirements, but buyers must consider the associated risks.

What is the delivery time for one container?

The delivery time is 15 working days after receiving payment for one container, applicable during both peak and off-peak seasons.

Product Q&A

Q:Why should I choose your company over cheaper competitors?

Unlike cheaper competitors who may use low-efficiency cells and skip quality tests, we perform 3 EL tests and 2 Flash tests to ensure no hidden cracks or mixed grades, preventing hot spots and fires.

Q:What are your payment terms and security measures?

We accept 30% advance and 70% before shipment, LC at sight, and Made-in-China STS. Third-party inspections like BV and SGS are supported before shipment.

Q:Can I inspect goods before shipment?

Yes, customers can arrange personnel or third-party companies like BV and SGS to inspect goods. For orders exceeding two containers, we cover the inspection cost.

Q:How do I apply for compensation if panels fail after 10 years?

Submit claim sheets along with the flash test report and warranty. We provide these documents with the product barcode upon shipment and offer after-sales service during the warranty period.

Q:Do you provide system design and installation services?

We offer professional design for grid, off-grid, and hybrid systems up to 1.27MW and provide remote online guidance. Door-to-door installation is not currently available.
