Advantages and benefits of Unex products
in photovoltaic installations
Electrical safety
Electrically insulating material.
High dielectric strength, protection of people against the risk of electrocution due to indirect contact.
The cable trays and trunkings eliminate grounding and equipotential bonding issues.
The insulating material prevents leakage currents and electric arcs between the cables and the cable trays or trunkings.
Cable protection
The cable trays and trunkings protect the wiring, improving the performance of the installation and extending its service life.
Cutting the products does not produce burrs that damage the insulation of the cables.
Tensile strength
The cable ties have high tensile strength according to EN 62275.
Outdoor experience
Over 45 years of experience in outdoor applications.
Resistance to prolonged exposure to ultraviolet rays, thanks to the specific formulation of the raw materials.
Corrosion resistance
Resistance to environmental corrosion (humid and saline) and to chemical agents.
Assembly and maintenance
No need for earthing or maintenance.
Easy to assemble and install.
Durability of Unex Cable ties
in photovoltaic installations
In photovoltaic installations, cable ties are the fundamental element for fastening and fixing cables.
The cable ties used must be especially resistant to weather conditions, high temperatures, and prolonged exposure to ultraviolet rays.
The formulation of our raw materials allows us to meet the most demanding technical requirements with both Cable ties 22-0 and Cable ties 22 HD.
If you have a photovoltaic project and need information about the durability of our cable ties, contact us by selecting the ones that interest you the most.
Applications in photovoltaic installations
with Unex products
Discover the types of photovoltaic installations where you can use Unex cable trays, trunkings and cable ties.
Installations in solar plants
A solar farm is a fixed or tracking installation made up of a set of solar panels installed on the
This type of installation is characterised by:
- Being located on rural land.
- Extreme weather conditions: high solar radiation, high temperatures, wind, rain, etc.
- Difficult access to the installation.
- Exposure to all types of rodents and birds.
Plant shutdowns, maintenance and the commuting of professionals generate high costs and reduce performance.
Distributing, protecting and tying the cables with products that meet very demanding technical requirements is essential to extend the lifespan of the plant and maximise its benefits.

Solar rooftop installations
Rooftop solar photovoltaic installations are mainly intended for self-consumption in the industrial, tertiary and residential sectors.
In this type of installation, easily accessed by anyone, stable electrical safety over time is essential. The use of products in insulating material protects the cables and guarantees electrical safety for both people and the installation.
Insulation is even crucial when the rooftop is metallic (in corrugated sandwich panel rooftops), where the insulating material electrically separates the installation from the building structure.
To improve the lifespan of the installation, it is important to protect the cables from the elements and from all types of birds and rodents, with electrically insulating products, making the installation twice as safe.
The cable distribution is carried out through protective trunkings installed on the surface. Depending on the type of rooftop, different supports are required, such as:
- On corrugated sandwich panel rooftops, the Strut channels 60 allow the base of the trunking to be spaced from the rooftop and ensure support when it is installed along the water drainage line.
- On flat rooftops, the Rooftop supports 60 do not require drilling the rooftop, as they stay in place thanks to their own weight.

Floating solar power plants
For a few years now, floating photovoltaic plants have been gaining importance, and these have a number of advantages over ground-mounted systems:
- They increase the energy production of the panels by 10-15% thanks to the cooling of the water.
- Reduce water evaporation from the occupied surface by more than 80%.
- Block algae growth, improving water quality.
- The energy generated in these plants, in addition to being sold, can be put to other uses such as solar pumping.
Among the main challenges of this type of installation are the high electrical risk caused by humidity, environmental corrosion, and the high maintenance cost, as these photovoltaic systems are located on lakes, ponds, reservoirs, the sea, etc. For this reason, the products used for cable protection and fastening must meet very demanding technical requirements that ensure electrical safety and protect against indirect contact.

Agrovoltaic installations
Agrovoltaic energy is positioned as a fundamental axis to make agriculture a more sustainable sector in the fight against climate change.
Distributing, protecting and tying the cables with products that meet very demanding technical requirements is essential to extend the life of the plant and maximise the performance of solar agricultural self-consumption installations:
- Durability against extreme weather conditions: high solar radiation, high temperatures, wind, rain, etc.
- Resistance to environmental and humidity corrosion.
- Protection of the cables against all types of rodents and birds.
- Stable electrical safety over time, avoiding plant shutdowns and protecting people against indirect contacts.
- Products that are easy to assemble and require no maintenance.

Installations in solar canopies
Installations in solar canopies are key to the energy transition, and there is an increasing trend towards this type of self-consumption in which the space dedicated to vehicle parking is used for the installation of solar panels.
Depending on the type of photovoltaic canopy, the needs of the electrical installation may vary, which is why the products for the distribution, protection and tying of the cables must be versatile and easily adaptable to each structure.
Other essential requirements for the products used in this type of photovoltaic installation are:
- Maximum electrical safety for both the installation and people. It is essential to insulate the installation from the structure, otherwise pedestrians would be exposed to indirect contact.
- Ease of installation.
- Durability
- Resistance to weathering and ultraviolet rays.

Inverters in photovoltaic installations
Solar inverters are a very important element in photovoltaic installations and an inadequate choice of cable protection elements can cause electrical failures and reduce the performance of the plants.
It is important to use insulating products that provide maximum electrical safety and protect the cables from the elements and from all types of birds and rodents to improve the lifespan of the photovoltaic system. In this way, we achieve a twice as safe installation.
In addition, the insulating products make installation easier, as they do not require grounding or maintenance and are resistant to corrosion and weathering.
