# Powering Up: Buying Solar & Energy Storage
The "New Energy" section of the Canton Fair (Phase 1) has exploded in size. 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.
