China dominates the entire solar supply chain. ## 1. Key Categories * **PV Modules:** Monocrystalline panels (PERC, TOPCon, HJT tech). * **Inverters:** String inverters, Micro-inverters, Hybrid inverters. * **Energy Storage (ESS):** Residential powerwalls, Portable power stations, Containerized industrial storage. ## 2. Tier 1 vs. Tier 2 * **Tier 1 Brands:** (Longi, Jinko, Trina). They have massive booths. Prices are fixed and high. MOQs are huge. * **Tier 2/3 Factories:** They often use the same cells but assemble them in smaller factories. Good for smaller distributors who want their own brand (OEM). ## 3. Shipping Lithium Batteries This is the hardest part. * **Dangerous Goods (DG):** Lithium batteries are Class 9 Dangerous Goods. * **UN38.3 Certificate:** You CANNOT ship without this. Ask for it immediately. * **Shipping:** Shipping costs for batteries are high. Ensure your margin calculation includes DG shipping fees. ## 4. Warranty Reality * Suppliers promise "25 Year Warranty". * **Reality:** Will the factory exist in 25 years? Probably not. Rely on third-party insurance or buy from established giants if warranty is your main selling point. ## Summary The tech moves fast. Currently, **N-Type TOPCon** cells are the hot product. If a supplier is pushing old P-Type Poly panels, offer them a liquidation price.
