Renewable Energy Cabling Systems
The renewable energy industry has grown rapidly as companies increasingly recognize its potential to reduce emissions and cut costs. Solar and wind farms produce massive amounts of energy that can be directed to diverse industrial processes. However, to do so, renewable energy providers must build resilient infrastructures that can handle challenging environments and changing energy demands. The wire, cable, hardware and equipment all constitute a key part of that infrastructure for generating, transporting, and storing electricity.

Commercial and Utility-Scale Solar Energy Production
The solar industry efficiently produces energy for a wide range of commercial sectors, each of which benefits from diversifying its energy sources.
Commercial solar power relies on large-scale solar photovoltaic (PV) power plants, which draw energy from hundreds of thousands of discrete panels. When the sun strikes one of these panels (or modules), its PV cells absorb the energy, generating an electrical field. The electricity then passes through an inverter on its way to a battery. Photovoltaic wire, or PV wire, is a single insulated conductor used to interconnect the solar panels in a solar farm.
Neither individual panels nor solar farms could function without a network of durable solar power wire, cable, hardware and equipment.
For this vital interconnection, solar energy wire and cables are used to connect these units and distribute the generated current. PV wiring is suitable for use in grounded and ungrounded photovoltaic power systems, generally rated up to 2 kV, in free air, raceways or direct burial in accordance with the NEC (United States) or Canadian Electric Code (CE). When leveraging open air installation wires are tied to racking, offering a fast and cost-effective solution.
How Solar Cables Support Large-Scale Renewable Energy Equipment
Solar panels themselves consist of frames that contain glass-covered solar cells. These cells are the units that generate charge in response to sunlight. The solar panels interconnect, resulting in strings, and lead back to a combiner box. Monitoring systems track energy yield and alert technicians to faults. These components work together to create solar energy for commercial buildings.
Photovoltaic Wire
- What is Photovoltaic Wire?
What is Photovoltaic Wire?
Solar panel interconnection strings go back to a combiner box. They are in an open air installation, tied to a racking system. This involves running a 12 AWG to 8 AWG wire from the combiner box to the ground in a short run (less than 100 feet).
PV wire can also connect combiner boxes to inverters. These wires are usually power-sized aluminum cables (4/0 AWG to 1000 kcmil) that extend for hundreds of feet. Direct burial or trench installation can accommodate many circuits in a single common trench. This cost-effective method allows for native backfill to support the foundation.
- Types of PV Wire
Types of PV Wire
PV wire comes in different varieties to suit different applications in the assembly.
AWG’s SunGuard XLPE Photovoltaic Wire is engineered specifically for grounded and ungrounded solar power connectors. These conductors are rated for high crush, moisture, and chemical resistance and can be used above and below ground.
- Selection Considerations
Selection Considerations
Wires are critical to the function of any PV system, so it’s important to choose the right ones for your system. The right PV wire is rated for the appropriate voltage and can withstand your installation and working conditions. Solar power equipment manufacturers are typically most concerned with:
Conductor Size
Conductor size is defined by conductor cross-sectional area, not diameter.
Material
Wires are typically available in aluminum or copper. Aluminum allows you to save money and weight. Copper wiring is on average about 3 times heavier than an aluminum wiring (8000 Series). Typical aluminum alternative to copper for a given circuit is: About 50% the weight of copper, and about 8% larger diameter (on average).
Insulation
Different conditions call for different types of insulation. Insulated wires are able to withstand voltage stresses, operate over a wide temperature range, and are better equipped to withstand mechanical abuse such as abrasion and flexing, as well as chemical attacks from water, oils, gases.
Solar Power Cables
- What are Solar Power Cables?
What are Solar Power Cables?
Cables for solar systems are a collection of multiple solar wires bound together by a jacket. They can accommodate higher voltages and may be used for connections above or below ground. Solar cables are specifically designed to withstand harsh weather conditions, including UV rays, moisture, and extreme temperatures.
- Types of Solar Power Cables
Types of Solar Power Cables
Solar cables differ based on their type, number, and arrangement of conductors, which determines their performance characteristics. Low-, medium-, and high-voltage cables are all available to fulfill different roles in a facility.
Another important distinction is whether a cable is compatible with grounded or ungrounded systems.
- Selection Considerations
Selection Considerations
Selection considerations for cables are similar to those for wires:
Size
The selected conductor size must be able to safely carry the maximum current generated by the system. Selecting a conductor size in accordance with the NEC or the Canadian Electrical Code is required for a safe, Code compliant installation.
Insulation
Cables are more likely to be used outdoors or underground, so they need to resist sunlight, moisture, varying temperatures, and chemical exposures. Ensure that the type and thickness of a cable’s insulation suit your application.
Cable Certification
Renewable energy cables should typically be UL-listed or CSA approved

Wiring Technology for Renewable Wind Energy
Turbines leverage power from the wind to provide clean, reliable energy. Today’s global wind power capacity sits at 743 gigawatts, according to the Global Wind Energy Council, and the industry continues to grow.
Wind turbines powering this production may be situated on land or offshore. Offshore turbines are significantly larger and generate more energy thanks to the massive power of ocean winds. Still, to maximize production, both kinds of turbines are often arranged into farms in very windy areas. However, they can also be installed at or near the site where the power will be used. In this case, they are referred to as distributed wind.
A wind turbine has propeller-shaped blades that spin around a rotor when they capture airflow. The rotor’s movement spins a generator, creating electricity.
The Instrumentation and Design Behind Large-Scale Wind Power
A typical turbine consists of blades connected to a rotor, both mounted on a tall shaft. The rotor connects to the nacelle, which is the box that contains the generator. Wind turbine cables are necessary to connect these components, but also to transport energy from the generator to its place of storage or use.
To function outdoors under varied conditions, wind turbine construction materials must be rugged while remaining lightweight. This is especially critical when considering offshore wind energy technology, which is buffeted by saltwater and high winds.
Wind Turbine Construction Materials: Wire & Cable
- What are Wind Farm Cables?
What are Wind Farm Cables?
Wind farm cables are the conductors used within wind farms, as well as those used to connect large-scale wind power to the electrical grid.
- Types of Wind Farm Cables
Types of Wind Farm Cables
Wind turbine energy cables vary in size, construction, and application. A typical turbine requires low-voltage cables in the nacelle, along with medium- and high-voltage cables to transport power within and beyond the tower. Control cables are also necessary to manage the flow of electricity.
- Selection Considerations
Selection Considerations
Different cables should be used at different points in a turbine or wind farm. Key considerations include:
Size
A cable’s size determines its voltage capacity and influences its physical properties, such as flexibility and torsional strength.
Insulation
Wind farm cables are often exposed to very low temperatures, saltwater, and oil. The entire cable’s construction should support these possibilities, but the most critical is its insulation.
Conductor
Both conductor size and material are considerable factors for selecting wind power cabling. Aluminum cables are increasingly replacing copper cables as tower and base components because aluminum is cheaper and 60% lighter. As for size, the larger the internal area of a conductor, the less resistance it creates. This allows cables to produce less heat and allow more current to pass through the conductor.
Low Voltage Cables
Medium Voltage Cables
Control Cables
Grounding Cables
Transmission Wire
Fiber Optic Communication Cables
Within the nacelle of a turbine, cables should be flexible and be able to resist vibrations and chemical exposures. The cables used to transport power should be larger to accommodate higher voltage, and they should have high torsional strength to withstand winds and turbine rotation.
To ensure that a cable can withstand the tough conditions of wind power applications, look for Wind Turbine Tray Cable (WTTC) approval and high flex rating.
