Which brand of solar cells do you use?

We hold CE, TUV, IEC 61215 and 61730, ISO 9001 / 14001 / 45001, UL, and can provide the certificates and reports required by your destination market.

Over 95% of our shipments are monocrystalline N-type TOPCon modules. Polycrystalline production has basically been phased out. If your project has a special requirement, we can discuss it separately.

Our standard output range is 450W to 720W with module efficiency of 21% to 23.5%. Our N-type TOPCon series can reach above 23%. We can match the exact power bin to your project.

We cover PERC, TOPCon, HJT and BC technologies, mainly 182mm and 210mm large-format single-glass and dual-glass modules ranging from 400W to 720W, suitable for residential roofs, C&I distributed projects and utility-scale ground plants.

You may request inspection within 15 days of delivery. Quality issues not caused by human factors are covered by free repair or replacement during the warranty period. Damage caused by improper installation, wiring errors, water ingress, lightning, or other human/force-majeure causes is not covered. Return shipping costs are borne by the responsible party.

Please check: 1. Whether the battery voltage is sufficient (low voltage causes output drop); 2. Whether total load power exceeds the inverter rating; 3. Whether surge power from inductive loads (AC, fridge) is within the inverter's tolerance (typically 2× rated power); 4. Whether AC connections are secure.
