Jinko Solar Storage and Unpacking Instruction of Photovoltaic Modules

2.1 Notes for Container Handling

Unloading tools: Forklift, unloading platform, or unloading pad tooling.

When unloading onto a platform or ground, use steel plate pads or tooling to assist in moving goods smoothly out of the container.

Unloading tools requirements: The length of the unloading platform or tooling (L) must be greater than or equal to the sum of the unloading forklift length (L1) and the module packing box length (L2) (L ≥ L1 + L2).

The height of the unloading platform and tooling should be level with the bottom of the container (loading bottom plate), with a height tolerance within ±10mm. The inclination angle between the fixture pad and the plane should be less than 5° to prevent the forklift from hitting the container top.

When the container is unloaded:

• Fuel Forklift: Adjust fork height from the ground. Insert forks into the short side of the pallet. Lift modules at an appropriate height (tilt angle < 2°). Ensure the distance from the ground when exiting the container door is such that fork height and distance from goods to container top are not more than 80mm.
• Horizontal Electric Forklift: The mechanical arm length should be ≥1800mm. Lift modules from the short side of the pallet with forks (fork height ≤40mm from the ground), moving modules out slowly.
• If unloading from the long side, fuel oil forklifts are required.

Diagram Description (Heights): The diagram shows H1 as the height of the module packing box and H2 as the height of the container door, relative to the height of the container above the ground.

When unloading, keep modules balanced. The forklift arm should be kept relatively horizontal. A 2-3cm spacing between modules and walls or adjacent modules is permissible. Forklift trucks should move modules out of the container slowly and smoothly to prevent carton damage from friction. As goods exit the container port, slow down and lower the forklift arm close to the bottom plate to reserve space. Pay attention to the distance between the bottom of the goods and the container top to prevent collisions. Ensure the entire pallet module is safely removed.

Choose flat ground for unloading to prevent tilting and unevenness affecting safety.

If modules require temporary storage after unloading, maintain sufficient space between pallets to prevent scratching cartons or pallets during subsequent transfers.

When unloading cross-loading modules, ensure the forklift does not exceed the modules and prevent damage to adjacent modules caused by forklift arm length.

Refer to other requirements for forklift unloading considerations.

2.2 Hoisting Precautions

• Use a longer nylon sling for crane unloading; wire rope is not allowed.
• Before lifting, ensure the sling length is evenly distributed on both sides to prevent case tilting and potential module damage.
• Keep the box balanced during lifting to avoid module tilting.
• During unloading, a spotter should direct lifting and dropping. Operations should be gentle to avoid touching or dropping the module box. Ensure the ground is level.
• Hoisting operations are strictly prohibited in adverse weather conditions such as winds greater than force 6, heavy rain, or snow.
• To minimize sling impact, use necessary support during loading/unloading, such as wooden sticks, iron rods, or tooling to support the sling on the box top, matching the outer box width. Use a metal steel pipe at the bottom of the pallet to fix the sling and reduce contact pressure.

2.3 Forklift Handling Precautions

• Select forklifts reasonably based on the size and weight of the goods. If fork length is less than 3/4 of the goods' size, use extension sleeves on the forks before lifting to prevent the packing container from tipping. (See Figure 1)
• When loading modules, adjust the spacing between the two forks as required. The load on the forks must be balanced without deflection. One side of the module package should be close to the retainer. (See Figure 2)
• The forklift truck's shelf wall should have cushions (e.g., foam or silicone pads) to prevent hidden cracks from collision or extrusion between modules and the shelf wall.
• When loading/unloading from the long side of the module, the forklift truck shelf wall height should be ≥1200mm, and the contact surface should be flat without protruding points to avoid collision or extrusion causing cracks and glass bursting. (See Figure 3)
• Avoid contact or collision with sharp objects (like forklift pallet forks) and module boxes to prevent damage to internal modules. (See Figure 4)
• For stacked modules, the forklift truck is prohibited from lifting more than one stack at a time.
• During loading and unloading, personnel other than the forklift operator must maintain a safe distance for safety.
• A dedicated person is required to command during loading and unloading to prevent failures and modules falling.
• When moving palletized packing boxes, lift and lower the forklift slowly and steadily, avoiding turbulence and violent vibration during transportation.

• Figure 3: Depicts the requirement for a high (≥1200mm) and flat forklift shelf wall when handling modules from the long side.
• Figure 4: Highlights the importance of avoiding sharp objects like forklift forks from contacting the module box.

3.1 Notes for Storage

• Due to complex environments and climates, store stacked modules on a single pallet after dismounting for safe storage. For double-glazed frameless modules, store them on a single pallet after dismounting.
• Store modules in their complete outer package. The storage area must be protected from dampness, direct sunlight, and rain.
• Storage areas should be kept dry, level, with a horizontal angle less than 10°.
• Ensure all modules of the same current class are stored centrally in the same area (e.g., square matrix, combiner box).
• Place modules neatly with a safe distance between boxes, greater than 30cm.
• Do not stack other items on modules or boxes.
• Note the storage information labelling instructions.

4.1 Packing Information

Jinko Solar modules are commonly packed using five standard methods. Select the appropriate unpacking method based on the specific package type:

• Packing method A: Shaking cap packing with no internal strap.
• Packing method B: Plan 1: Conventional packing.
• Packing method B: Plan 2: With internal wooden protectors.
• Packing method B: Plan 3: With exterior wooden protectors and cross-packing.
• Packing method B: Plan 4: Exterior cross packing.

4.2 Unpacking Methods

Unpacking method A (Shaking cap packing with no internal strap)

1. Cut off straps within the two pallets and use a forklift to separate them.
2. Cut off the packing straps of the single pallet and remove the isolated wood (or plastic wrap) and the carton cover.
3. Remove the first module labeled "1" from the opening position (marked in red) first. Then remove the remaining modules sequentially.
4. When the last 5 pieces of modules are left in the box, place them on a solid support on the side to prevent the box from tipping over due to strong wind or accidental collision.

Unpacking method B: Plan 1 (Conventional packing)

1. Remove the wrapping film around the box and separate the upper and lower boxes.
2. Position the long side of the module to be unpacked near a solid support (wall, rack, or another unpacked module box) for about 15-20cm. Cut all packing straps of the outer box with scissors.
3. Remove the top cover of the box and lift off the carton. Two persons should hold the modules to prevent tipping. Another person cuts the upper-middle horizontal straps and vertical straps of the modules, retaining the bottom horizontal strap.
4. Stand on both sides of the short side of the module and slowly lean it towards the support. Once completely leaning, cut the remaining bottom horizontal packing strap on the short side. Finally, remove all modules sequentially from the outer one.
5. Note: When cutting internal packing straps, stand on both short sides of the module to prevent sliding and potential injury.

Unpacking method B: Plan 2 (With the internal wooden protectors)

1. Remove the wrapping film around the box and separate the upper and lower boxes.
2. Position the long side of the module to be unpacked near a solid support (wall, rack, or another unpacked module box) for about 15-20cm. Cut all packing straps of the outer box with scissors.
3. Remove the top cover of the box and lift off the carton. Cut the horizontal straps on the wooden protectors and then remove the wooden protectors.
4. Two persons should hold the modules to prevent tipping. Another person cuts the upper-middle horizontal straps and vertical straps of the modules, retaining the bottom horizontal strap.
5. Stand on both sides of the short side of the module and slowly lean it towards the support. Once completely leaning, cut the remaining bottom horizontal packing strap on the short side. Finally, remove all modules sequentially from the outer one.
6. Note: When cutting internal packing straps, stand on both short sides of the module to prevent sliding and potential injury.

Unpacking method B: Plan 3 (With the exterior wooden protectors and cross-packing)

1. Remove the wrapping film around the box, then cut the cross-packing straps and remove the exterior wooden protectors.
2. Cut the straps of the upper and lower modules packages, then separate the upper and lower modules boxes.
3. Position the long side of the module to be unpacked near a solid support (wall, rack, or another unpacked module box) for about 15-20cm. Cut all packing straps of the outer box with scissors.
4. Remove the top cover of the box and lift off the carton. Two persons should hold the modules to prevent tipping. Another person cuts the upper-middle horizontal straps and vertical straps of the modules, retaining the bottom horizontal strap.
5. Stand on both sides of the short side of the module and slowly lean it towards the support. Once completely leaning, cut the remaining bottom horizontal packing strap on the short side. Finally, remove all modules sequentially from the outer one.
6. Note: When cutting internal packing straps, stand on both short sides of the module to prevent sliding and potential injury.

Unpacking method B: Plan 4 (Exterior cross packing)

1. Remove the wrapping film around the box, then cut the cross-packing straps.
2. Cut the straps of the upper and lower modules packages, then separate the upper and lower modules boxes.
3. Position the long side of the module to be unpacked near a solid support (wall, rack, or another unpacked module box) for about 15-20cm. Cut all packing straps of the outer box with scissors.
4. Remove the top cover of the box and lift off the carton. Two persons should hold the modules to prevent tipping. Another person cuts the upper-middle horizontal straps and vertical straps of the modules, retaining the bottom horizontal strap. (Note: The distribution of packing straps inside the package may vary but does not affect the order of removal.)
5. Stand on both sides of the short side of the module and slowly lean it towards the support. Once completely leaning, cut the remaining bottom horizontal packing strap on the short side. Finally, remove all modules sequentially from the outer one.
6. Note: When cutting internal packing straps, stand on both short sides of the module to prevent sliding and potential injury.

4.3 Unpacking Precautions

• When opening cartons outdoors, avoid operating on rainy days as cartons can soften and spread, potentially damaging modules.
• For disassembled modules during outdoor wind operations, use fixed measures and avoid moving modules to prevent damage.
• Store modules in a ventilated, rainproof, and dry place before unpacking.
• Use scissors or an art knife to cut outer box packing tape. Do not scratch the glass. Confirm the number of modules in the box immediately after opening.
• Ensure the working ground is stable and horizontal to prevent packing boxes from tipping.
• Wear protective gloves during unpacking and handling to avoid scratching hands or leaving fingerprints on the glass.
• Each module must be carried by 2 people. Do not pull the junction box. When lifting, grab the short edge and take out the module. (See Figure 5)
• When removing modules (for packing method A), use protective tooling to separate them and prevent friction-induced flecks. Avoid hard pulling and skewed drawing. (See Figure 6)
• Before installation, cut the binding band of the fixed wire to prevent the connector from hitting and damaging the modules.
• Do not remove corner guards from modules before installation.
• Place remaining installed modules centrally and protect them with the packing case.

Figure Descriptions:

• Figure 5: Illustrates carrying a module by its short edge with two people.
• Figure 6: Shows using protective tooling to separate modules during unpacking to prevent friction damage.

4.4 Instruction for Transshipment and Handling at Project Site

• Transshipment of the packing box should be completed before removing the outer packing case. After unpacking, modules should not be transshipped without fixed protection of the packaging material. Repackage before transport or use manual short-distance lifting.
• When transporting modules at the project site, select a smooth road to avoid damage or cracks caused by turbulence, collision, extrusion, or tilt. Modules must be transported on flat ground.

5.1 Instruction for Sampling at Project Site

• For spot testing, refer to the unpacking instructions to unbox the modules.
• After removal from the box, place modules on a vacant pallet. Carry modules by two people and handle with care during sampling. (See Figure 7)
• Precautions during sampling to avoid secondary cracks:
• a) To remove cable ties: Hold the connector upward with your right hand, twist, and pull slightly upward. Use scissors to cut the ties. Avoid hitting the rear side of the module with the connector. (See Figure 8)
• b) Connecting connectors: Do not shake the cable when connecting to avoid damaging the module.
• c) Turning modules over: Use fixing measures (e.g., adhesive tape) to secure connectors and prevent cracks caused by connectors dropping. (See Figure 9)
• d) After testing: Remove tape from the cable, re-tie the cable, and repack modules for secondary transport.

Figure Descriptions:

• Figure 7: Shows modules placed on a pallet, ready for sampling, handled by two people.
• Figure 8: Illustrates the correct method for removing cable ties, holding the connector up.
• Figure 9: Depicts using tape to secure connectors when turning a module over.

5.2 Instruction for Sample Modules

• Sample modules must be selected with no damage to the outer package.
• If the client requires a second transfer of modules, Jinko is only responsible for the EL test results of the modules at the first unloading point.
