How Many Solar Panels Fit in a 40HQ Container? Real Numbers by Model
How Many Solar Panels Fit in a 40HQ Container? Real Numbers by Model
Container quantity is one of the first things a distributor needs to know, because it sets the freight cost per watt. The answer is not a single number. It depends on module size, pallet packing and the carrier weight limit. The figures below come from the manufacturer datasheets we supply for five current models, with the pallet and weight arithmetic shown so you can check it yourself.
The short answer
Most 600 to 720 W modules load 496 to 720 pieces per 40HQ, packed on 16 to 20 pallets. Larger, heavier modules carry fewer pieces per container but more watts per piece, so the total megawatts per container ends up in a similar range.
Datasheet figures by model
| Model | Power | Pieces per pallet | Pallets | Pieces per 40HQ | Module weight | Total cargo weight (calculated) |
|---|---|---|---|---|---|---|
| Trina Vertex N TSM-EG21C.20 | 700 W | 33 | 18 | 594 | 38.3 kg | approximately 22.8 tonnes |
| LONGi Hi-MO9 LR7-72HYD | 650 W | 36 | 20 | 720 | 28.5 kg | approximately 20.5 tonnes |
| Jinko Tiger Neo 66HL4M-BDV | 600 W | 36 | 20 | 720 | 32.4 kg | approximately 23.3 tonnes |
| Canadian Solar CS7L-630TB-AG | 630 W | 33 | 18 | 594 | 34.5 kg | approximately 20.5 tonnes |
| JA Solar JAM78D30-605/MB | 605 W | 31 | 16 | 496 | 34.6 kg | approximately 17.2 tonnes |
Total cargo weight is calculated as pieces per container multiplied by module weight. It excludes pallets, packaging and container tare. Manufacturer packing data can change by revision, so confirm against the datasheet for the exact model and production batch.
Why the numbers differ
1. Module footprint and pallet layout
A 2384 mm module, such as the Trina 700 W or the Canadian 630 W, takes a longer pallet than a 2382 mm module that is 1134 mm wide, such as the LONGi 650 W or the Jinko 600 W. As a result, fewer pieces fit per pallet. The JA 605 W uses a 31-piece pallet, which reduces the container count further.
2. Pallet stacking and container height
Manufacturers typically stack two pallets per stack for a 40HQ. The loading plan must leave clearance for the door height and allow the forklift to work, which is why the theoretical pallet count and the actual count can differ by one or two pallets.
3. Weight, not volume, can be the limit
A 40HQ has a nominal payload in the region of 26 to 28 tonnes, but the exact limit depends on the carrier, the route and the verified gross mass rules at the port. The heaviest case above is the Jinko 600 W at approximately 23.3 tonnes of modules, before pallets and packaging. That is normally within limits, but the carrier figure governs.
How to calculate it for any module
Use this sequence:
- Pieces per pallet, from the datasheet packing section.
- Pallets per 40HQ, from the same section or from the loading plan.
- Pieces per container, which is pieces per pallet multiplied by pallets per container.
- Total cargo weight, which is pieces multiplied by module weight. Add pallets and packaging, then compare with the carrier payload.
- Total megawatts, which is pieces multiplied by module watts, then divided by one million.
Example for the Trina 700 W: 33 pieces per pallet multiplied by 18 pallets gives 594 pieces. 594 pieces multiplied by 38.3 kg gives 22,750 kg. 594 pieces multiplied by 700 W, then divided by one million, gives 0.416 MW per 40HQ.
What to ask your supplier for
- The datasheet revision that matches the production batch, not a generic brochure.
- A packing list showing pallet dimensions, pieces per pallet and gross weight.
- Confirmation of the carrier payload limit for your route.
- Photos of the loaded container and pallet labels if you are buying on FOB terms.
Bottom line
For current 600 to 720 W modules, plan on roughly 500 to 720 pieces per 40HQ and 17 to 23 tonnes of modules. The precise figure is a datasheet and carrier question, not a rule of thumb. If you send us the model and destination port, we will return the packing plan and the freight calculation together.
