Product Q&A
Q:Why should I choose your company if others offer 10% cheaper prices?
A:
Cheaper panels often use low-efficiency cells without Flash and EL testing, leading to cracks and fire risks. GAMKO performs 3 EL tests and 2 Flash tests to ensure quality and avoid hidden defects.
Q:What are the payment terms and security measures for first-time buyers?
A:
We accept 30% advance and 70% before shipment, LC at sight, and STS via third-party platforms. Third-party inspections are accepted before shipment.
Q:Can I arrange personnel to inspect goods before shipment?
A:
Yes, customers can use third-party companies like BV or SGS for on-site testing. For orders exceeding two containers, we cover the inspection cost.
Q:How do I apply for compensation if solar panels have problems after 10 years?
A:
Submit claim sheets with the flash test report and warranty. We provide after-sales service throughout the warranty period.
Q:Why are some Tier 1 solar panels very cheap?
A:
Cheap panels often come from unauthorized traders, lack export permits, and may be fake or degraded stock. Buying from unqualified traders risks confiscation and no warranty.
