Frequently Asked Questions
What material is used for the solar power copper busbars?
We use T2 / C11000 high purity copper (≥99.99%) ensuring exceptional conductivity of ≥97% IACS and low resistivity for optimal performance in photovoltaic installations.
Can I customize the dimensions and configurations of the grounding copper bar?
Yes, we support full customization. You can customize the thickness (2mm to 10mm), width (10mm to 200mm), length (up to 6000mm), as well as specific hole drillings, bending angles, and shapes based on your engineering drawings.
What surface treatments are available for the copper busbars?
We offer Bare Copper, Tin Plating, Nickel Plating, and Silver Plating. These surface finishes enhance corrosion resistance, prevent oxidation, and ensure stable electrical contact in outdoor solar environments.
What is your typical lead time for samples and mass orders?
Sample delivery typically takes 3-5 working days. For mass production orders, the standard lead time is 7-15 working days. We also accommodate urgent orders depending on your project schedule.
What are your minimum order quantity (MOQ) and accepted trade terms?
Our standard MOQ is 100 pieces, but we are open to negotiating smaller trial orders. We support multiple trade terms including EXW, FOB, CFR, CIF, and DDP to match your logistics preferences.
How are the busbars packaged to prevent damage during shipping?
We pack the products using anti-rust paper and bubble film, then place them in sturdy export cartons or wooden boxes. This moisture-proof and damage-proof packaging ensures safe long-distance sea, air, or express transit.
