Leading solar cable manufacturers
At Custom Designed Cables, we are experienced solar cable manufacturers, designing and manufacturing custom solar cables for photovoltaic (PV) systems across a wide range of commercial and industrial applications. With over 20 years of cable manufacturing experience, we produce bespoke cable solutions tailored to your exact installation requirements while maintaining high standards of quality, reliability and performance.
Custom solar cables for photovoltaic systems
Solar cables are a range of products designed for the interconnection of photovoltaic systems.
Solar cables for photovoltaic systems are used as the interconnect between roof-mounted solar panels and the inverter unit. The inverter converts the DC voltage created by the panel into AC voltage electricity so it can be used on a domestic circuit or fed into the grid.
Our custom solar cables are typically manufactured using highly flexible Class 5 tinned copper conductors. These cables are also generally double insulated, providing excellent abrasion resistance, and are made from high-quality halogen-free materials that offer oil resistance, high flame retardancy, UV resistance and ozone resistance to ensure long-term durability and performance in outdoor environments.
In addition, our solar cables are able to withstand significant temperature variations and are typically rated between -15°C and +90°C for fixed installations, with the option to increase this to between -40°C and +120°C for the most demanding operating environments. The most commonly used conductor sizes are 4mm² and 6mm², although commercial installations may require alternative cable sizes depending on the scale and requirements of the project.

Frequently asked questions about solar cables
What is a solar cable?
A solar cable is a specialist electrical cable designed to connect components within photovoltaic (PV) systems, including solar panels and inverters. Solar cables are engineered to provide reliable electrical performance while withstanding long-term outdoor exposure.
What’s the difference between a solar cable and a standard electrical cable?
Solar cables are specifically designed for photovoltaic installations and typically offer enhanced UV resistance, ozone resistance, flexibility and temperature performance compared with many standard electrical cables, making them suitable for demanding outdoor environments.
Can solar cables be customised?
Yes. At Custom Designed Cables, we specialise in manufacturing custom solar cables tailored to your application’s electrical, mechanical and environmental requirements. We can produce bespoke cable constructions for a wide range of photovoltaic projects.
What conductor sizes are commonly used for solar cables?
The most commonly used conductor sizes are 4mm² and 6mm². However, larger commercial installations may require alternative cable sizes depending on the design and scale of the system. Get in touch for personalised advice regarding your specific project.
Are your solar cables suitable for outdoor installations?
Yes. Solar cables are specifically designed for outdoor use and incorporate UV-resistant and ozone-resistant materials to withstand prolonged exposure to environmental conditions while maintaining reliable performance.
Do your solar cables comply with industry standards?
Yes. At Custom Designed Cables, we manufacture our solar cable range in compliance with international standards wherever applicable, ensuring every project meets the required quality and performance expectations. These can include international standards such as IEC 62930 (covering single-core, halogen-free PV cables rated up to 1.5 kV DC), European standards such as EN 50618 (for low-smoke, halogen-free, flexible single-core power cables with cross-linked insulation and sheaths), and any other relevant international or national regulations.
