Shipping solar equipment: what can go wrong
Solar panels, inverters and their hardware are fragile, moisture-sensitive and high-value. Most damage comes from impact, moisture and heavy parts pressing on glass, and a micro-cracked panel can lose power output without looking damaged at loading. Careful packing, clean handling and secure loading prevent cracks, electrical faults and surface defects. This guide covers non-dangerous-goods (non-DG) equipment only: panels, inverters, mounting hardware and other power components. Lithium batteries and chemical-based storage units are dangerous goods and need DG compliance, so they are not covered here.

Panels, inverters and racking differ in fragility, weight and packing needs, so each needs its own handling.
Solar cells crack easily. Even micro-cracks reduce power output, and they may not be visible at loading.
- Use factory-approved cartons with corner protection
- Keep panels upright, never flat
- Don't drop, slide or drag cartons
- Band pallet loads so they stay stable
- Handle inverters as fragile electronics
Moisture reduces panel performance, corrodes connectors and damages inverter circuitry.
- Load in dry conditions
- Pack electronics in moisture-barrier packaging
- Add desiccants on long ocean routes
- Keep cartons away from the container walls
Panel glass scratches easily, which cuts efficiency and resale value.
- Separate each panel with foam sheets
- Never rub or drag across the glass
- Don't stack loose panels
- Fit pallet-edge protectors
Brackets and rails are dense and can crush panel cartons if stacked on top of them.
- Keep heavy brackets apart from fragile panels
- Stack by weight, heaviest at the bottom
- Use reinforced pallets for hardware
Inverters, controllers and connectors are sensitive to vibration, shock and moisture.
- Pack in foam or molded inserts
- Double-box sensitive items
- Label fragile electronics clearly
Documents to prepare
| Document | Why It Matters |
|---|---|
| Commercial Invoice & Packing List | States panel type, wattage, HS code and component specs |
| Certificate of Origin | Confirms where the goods were made; many customs authorities require it |
| Technical specification sheet | Supports classification of PV modules and electrical components |
| Test certificates (if requested) | Some buyers and inspectors use them to verify quality |
| Pallet and crate packing list | Lets the receiver check every pallet and crate on arrival |
What customs checks, by destination
Accurate paperwork helps avoid customs queries.
- Certificate of origin (COO) required
- Panel type and wattage checked against your documents at clearance
- Certificate of origin (COO) required
- Material composition and RoHS applicability checked for electrical components
- Certificate of origin (COO) mandatory
- Panel condition often inspected at delivery
Choosing FCL, LCL, air or crates
Whatever the mode, secure packing and correct orientation reduce damage risk.
| Mode | Best For | |
|---|---|---|
| FCL | Large shipments of PV modules and mounting hardware | - |
| Palletized LCL | Small quantities and mixed-component orders | - |
| Air | Urgent inverters or small panel shipments | - |
| Crates / vertical pallets | Fragile or high-value panels | - |

Solar shipping FAQs
No. They ship at ambient temperature but need protection from moisture and impact.
No. Ship them upright: it reduces stress on the glass and prevents micro-cracks.
No, unless they are packed with batteries. Non-DG electronics ship as standard cargo.
Impact shocks, moisture, and heavy hardware pressing on fragile items.
Only if they ship on wooden crates or pallets, which must meet ISPM-15.
