Photovoltaic manufacturing connects long, sensitive, and highly automated processes. From crystal growing and wafer slicing to solar cell production and module assembly, each workshop handles different carriers, loads, interfaces, and cleanliness requirements. A single robot model cannot solve every material-flow problem.
As KH Group engineers, we design workshop-specific AMR combinations and plant-wide control strategies that connect machines, buffers, warehouses, and production lines without forcing every process into the same handling method.
Executive summary: A practical photovoltaic factory logistics system should match the robot to the carrier, load, docking point, and process rhythm. KH Group combines lurking lift AMRs, omnidirectional AMRs, fork-type AMRs, load-carrying AMRs, integrated AMRs, long-fork AMRs, and the MCS system to automate material movement across the four principal photovoltaic workshops.
Why Does Photovoltaic Manufacturing Need an Integrated AMR Logistics System?
Photovoltaic production is not one continuous handling task. It is a sequence of specialized workshops with different materials and risks. Long crystal components are difficult to move manually. Wafer slicing requires accurate docking around slicing equipment and water-tank handling. Solar cell production depends on frequent cassette and carrier movement. Module assembly adds heavy glass, encapsulant materials, and finished modules.
The engineering objective is not simply to replace forklifts or operators. It is to create a controlled material-flow layer that supports production rhythm, reduces manual contact, improves delivery repeatability, and provides a foundation for traceable operations.
Long, heavy, fragile, or process-specific carriers require purpose-matched robot structures and fixtures.
Automated loading and unloading depend on repeatable positioning, stable handoff, and interface coordination.
Production lines need timely replenishment without introducing avoidable congestion or manual waiting.
A unified control layer helps coordinate mixed fleets, routes, tasks, charging, and equipment status.
Begin AMR planning with the material carrier and transfer interface, not with a robot model. Confirm load dimensions, center of gravity, pickup direction, docking tolerance, cycle time, aisle width, floor condition, and upstream/downstream equipment signals before selecting the AMR.
How Can AMRs Automate Logistics in a Crystal Growing Workshop?
Crystal growing areas handle long or bulky material carriers and operate around tall process equipment. Manual transport can be labor-intensive and may expose operators to unnecessary traffic and environmental risks. The solution must also manage several carrier types instead of one standardized pallet.
KH Group uses a combination of lurking lift AMRs, omnidirectional lurking lift AMRs, and fork-type AMRs. This allows the system to move loading carts, recharging carts, crystal-material carts, and pallets according to their pickup and docking requirements. Laser-based navigation and visual positioning can support accurate task execution at defined stations.
Transport Objects
Typical objects include disassembly or initial-loading carts, recharging carts, crystal-material carts, and pallets. Their dimensions and pickup points should be standardized wherever possible.
Recommended Logistics Combination
The lurking lift AMR handles compatible carts from below, the omnidirectional model supports constrained alignment and lateral movement, and the fork-type AMR handles palletized or fork-access loads.
Main Transport Flow
What AMR Combination Works for a Wafer Slicing Workshop?
Wafer slicing workshops present two major engineering challenges: demanding equipment docking and variable floor conditions. Water, oil, cutting wire, and airborne particles can affect the operating environment, while loading and unloading around slicing machines requires controlled positioning.
Our recommended combination includes load-carrying AMRs, water tank transport AMRs, lurking lift AMRs, and fork-type AMRs. Each robot is assigned to the transport unit it can handle most reliably, while the fleet control strategy prevents different tasks from interfering with one another.
Transport Objects
Typical loads include crystal ingots or crystal carriers, water tanks, material racks, and pallets. Fixtures should restrain movement and protect the load throughout acceleration, turning, and docking.
Recommended Logistics Combination
A load-carrying AMR can support dedicated process fixtures, while a water tank transport AMR handles tank movement. Lurking lift and fork-type AMRs cover trolley and pallet transport.
Main Transport Flow
For slicing applications, site verification should include floor friction, drainage areas, contamination exposure, turning clearances, and actual equipment handoff tolerances. These details affect wheel selection, protection measures, localization stability, and docking design.
How Do AMRs Support Solar Cell Workshop Automation?
Solar cell production involves frequent movement of cassettes, carriers, flower baskets, and process fixtures. Manual handling can create inconsistent delivery timing and increases the chance of material or information mismatch. Stable automation therefore requires both physical transport and reliable task data.
KH Group combines lurking lift AMRs, integrated AMRs, and the MCS system. The robots execute carrier transfers, while the control layer exchanges task and status information with production equipment and relevant factory systems. The result is a closed material-flow loop rather than a collection of isolated robot routes.
Transport Objects
Typical objects include flower-basket carts, cassette or magazine carts, and graphite-boat racks. Carrier identification and orientation must remain consistent at each machine interface.
Recommended Logistics Combination
Lurking lift robots serve mobile carts, integrated AMRs can dock directly with selected process interfaces, and the MCS system coordinates equipment requests, task assignment, and material-flow information.
Main Transport Flow
How Can AMRs Improve Module Assembly Logistics?
Module assembly combines large, fragile, and heavy materials. Glass requires careful handling, encapsulant and related materials must arrive at the correct process point, and finished modules need safe transport without blocking production aisles.
KH Group deploys lurking lift AMRs, fork-type AMRs, and long-fork AMRs according to the load geometry and pickup method. A long-fork configuration is useful where extended or wide loads require greater support, while lurking lift AMRs automate compatible trolleys and fork-type robots handle palletized goods.
Transport Objects
Typical loads include glass, encapsulant films and related materials, material-box carts, and finished module pallets. The fixture design should limit sliding, tilting, and local stress on fragile goods.
Recommended Logistics Combination
The mixed fleet supports under-rack pickup, pallet handling, and long-load transport. The final selection depends on load footprint, fork entry, rack design, center of gravity, and aisle geometry.
Main Transport Flow

What Do Photovoltaic AMR Applications Look Like in Real Workshops?
Simulation is valuable during design, but a reliable deployment must also account for the real production environment. Machine legs, temporary obstacles, reflective floors, shared aisles, carrier variation, and maintenance access can all affect the final route and docking design.
Wafer Slicing Production Workshop
AMRs circulate between production equipment and material handoff points, supporting automated delivery through a dense equipment layout.
Solar Cell Production Workshop
Multiple AMRs support high-frequency carrier movement and line-side delivery while operating around production equipment.
Solar Cell Warehouse
Fork-type mobile robots connect storage and production areas, reducing repeated manual handling across longer routes.
Large Photovoltaic Module Manufacturing Base
Fork-type AMRs handle palletized production materials across a large facility and support safer, more visible traffic management.
Which KH Group AMR Should You Select?
AMR selection should follow the real transport task. A low-profile robot is suitable only when the carrier has compatible under-clearance and positioning features. A fork-type robot requires verified fork pockets, load stability, and turning space. Omnidirectional motion becomes valuable where the process needs side movement or precise alignment in constrained areas.

What Should Be Confirmed Before AMR Deployment?
We recommend completing a joint site and process review before finalizing the fleet. This prevents a technically capable robot from being paired with an unsuitable carrier or an unverified machine interface.
- Material data: size, mass, center of gravity, fragility, and orientation.
- Carrier data: wheels, fork pockets, under-clearance, rigidity, and positioning features.
- Station data: docking direction, tolerance, lift height, sensors, and handshake logic.
- Route data: aisle width, turns, intersections, doors, elevators, and shared traffic.
- Floor data: flatness, joints, ramps, water, oil, dust, and reflective surfaces.
- Capacity data: transport frequency, peak demand, buffer size, charging, and redundancy.
- System data: MES, WMS, equipment, MCS, network, and material ID interfaces.
- Safety data: pedestrian zones, blind corners, restricted areas, and emergency procedures.
A Practical Implementation Sequence
A pilot route should represent the real difficulty of the project. It should include actual loads, production calls, docking points, traffic interactions, charging logic, exception handling, and recovery procedures. Once the pilot is stable, the same engineering rules can be expanded to additional lines and workshops.
Why Work With KH Group on Photovoltaic Factory Logistics?
Photovoltaic intralogistics requires more than mobile robot hardware. The robot, carrier, machine interface, route, control system, and operating procedure must work as one solution. Our engineering approach begins with the production process and then selects the appropriate AMR structure and control method.
KH Group can support single-workshop automation, mixed-fleet deployment, line-side material delivery, machine docking, warehouse-to-production transfer, and broader intelligent logistics planning. The objective is a solution that is measurable, maintainable, and ready for real production conditions.
