Product Overview
10mm DC Solar Cable moves beyond standard string wiring into the territory of DC collection and medium-distance power routing. With a 10mm² tinned copper conductor, it delivers meaningfully lower resistance per meter than lighter cable sizes - which translates directly into less energy lost in transit between the array and the inverter. For commercial rooftops, industrial plants, and mid-scale ground-mounted systems, it fills the gap between everyday string cable and the heavy-duty sizes reserved for trunk-line duty.

Core Uses
10mm cable enters the picture when the DC side of a solar project starts to look less like a collection of short string leads and more like a structured power distribution network. It is the practical middle ground, strong enough to handle higher-load collection circuits, but not so heavy that it complicates installation or drives up material cost unnecessarily.
DC Collection Between Combiner Points
When several strings converge at a combiner box and the combined current needs to travel onward to the inverter, 10mm cable carries that load with a comfortable electrical margin. It reduces the voltage drop that accumulates across collection-level circuits, protecting system yield.
Medium-Distance Equipment Connection
In many commercial and industrial projects, the inverter room is not right next to the array. Cable paths of 30 to 60 meters are common. At these distances, 10mm cable provides noticeably better performance than 6mm, enough to make a real difference in energy delivery without jumping to a much heavier gauge.
Larger Rooftop and Ground-Mounted Arrays
As installed capacity grows, so does the current flowing through DC-side circuits. 10mm cable supports the higher current levels found in commercial rooftops, warehouse installations, and medium-scale ground-mounted systems where 4mm or 6mm cable would be undersized for the job.
Application Scenarios
Commercial Rooftop Solar
On commercial rooftops such as shopping centers, office buildings, logistics warehouses, 10mm cable handles the DC collection between array sections and centralized inverter equipment. It keeps line losses under control across the kind of cable distances that commercial buildings typically create, and its durability holds up to the foot traffic and maintenance access common on working rooftops.
Industrial Plant Installations
Factories and production facilities often have large roof areas but place electrical equipment in dedicated rooms some distance away. 10mm cable bridges that gap efficiently, carrying higher DC current across the building without the voltage drop penalty that lighter cable would impose.
Mid-Scale Ground-Mounted Projects
For ground-mounted systems in the hundreds-of-kilowatts range, 10mm cable works well as the collection-level wiring between string groups and field combiner boxes. Its outdoor construction handles direct burial in conduit, open-air cable tray routing, and the general wear of field installation.
Solar Plus Storage DC Circuits
In PV systems paired with battery storage, certain DC-side circuits carry more current than standard string cable can handle efficiently. 10mm cable fits these heavier circuits, between battery racks and DC buses, or between combiner outputs and hybrid inverter inputs.
Selection Guide
10mm DC Solar Cable is the right choice when the circuit goes beyond basic string interconnection and starts functioning as a collection or distribution line. Consider it when:
- Combined circuit current exceeds the comfortable range of 6mm cable
- Cable routing distance falls in the 30–60 meter range
- The project is commercial or industrial scale with higher installed capacity
- Voltage drop analysis shows lighter cable sizes are marginal for the planned route
For standard residential string wiring, 4mm or 6mm is usually sufficient. For heavy-duty trunk lines, long-distance transmission, or very high current circuits, 16mm or 25mm provides the next level of capacity.
Delivery and Technical Support
Cable is supplied in coils, rolls, or export drums depending on order volume and logistics requirements. Custom length cutting, private-label marking, and project-specific packaging are available.
Technical support covers cable selection based on system voltage, circuit current, installation method, and route length. Specification sheets, test reports, and export documentation can be coordinated for project buyers, distributors, and EPC contractors.
