Frequently Asked Questions

How does your quality control compare to cheaper alternatives on the market?
Some cheaper modules skip flash and EL testing, which leads to cell cracks and high risk of hot spot effects or fires. Our process features 3 distinct EL tests and 2 Flash tests—from string welding to final output—to ensure there are no micro-cracks or grading mismatches. We rely on high-precision automated machinery rather than manual assembly to preserve the durability and lifetime of every panel.
What payment options do you support to ensure security for first-time buyers?
We support standard 30% prepayment with 70% due before dispatch, and accommodate third-party inspections before final payment is made. L/C payment options are also available. Additionally, verified transaction portals (such as the secure platform of Made-in-China) can hold payments until proof of shipment documents are officially generated.
Can we perform third-party testing on-site before payment?
Yes, we highly welcome external testing agents (such as BV, SGS, or CQC inspectors) to run on-site testing. We fully cooperate with audit teams. For large-scale orders exceeding two full container volumes, we can subsidize the third-party inspection cost to ensure a long-term partnership.
How is the module warranty structured and tracked?
Every shipment is cataloged with barcode tracking, physical warranty agreements, and individual Flash Test Reports. Users can submit the official warranty sheet alongside the product barcode if any power output degradation occurs during the warranty duration to claim replacement parts.
What risks exist with unauthorized brand sales?
Purchasing through unauthorized distributors exposes buyers to fake panels, rejected warranties, and custom holds or heavy fines due to the absence of valid export authorization. Improper stock preservation and prolonged storage in damp settings will degrade panel power and lifespan significantly.
Do you offer system configuration design and installation guidance?
Yes. We design hybrid, on-grid, and off-grid configurations, with previous systems engineered up to 1.27MW. We provide bracket blueprints and structural details. For installation, we provide remote, video-assisted structural setup support, but do not provide door-to-door installation teams at the moment.
