The expansion project aimed to add 120 MW of photovoltaic capacity, requiring high-performance, durable cables to withstand the harsh desert environment and ensure stable long-term operation. As a professional wire and cable exporter with rich experience in renewable energy projects, we provided a comprehensive cable solution, solving the client’s core pain points and establishing a long-term cooperative relationship. This case study details how we used H1Z2Z2-K Solar Cable, H07V-K, and PVO7AC-F Cable to support the project’s smooth progress and deliver tangible value to our client.

1. Challenges of Solar Park Expansion in Morocco’s Desert Environment

The client, a leading Moroccan renewable energy engineering company, was responsible for the expansion of the Noor Solar Park. The project faced unique challenges due to its location and scale, which became the core pain points our team needed to address. First, the desert environment in Ouarzazate is extremely harsh: high temperatures reaching 50°C in summer, sudden temperature drops at night, intense ultraviolet (UV) radiation, and occasional sandstorms. Ordinary cables would degrade quickly under such conditions, leading to frequent failures, high maintenance costs, and even safety hazards like short circuits or fires. Second, the project had strict time constraints—any delay in cable supply would hold up the entire construction schedule, resulting in significant economic losses. Third, the client lacked experience in selecting cables for large-scale solar projects, especially for high-voltage DC and AC connections, and was worried about choosing products that did not meet international standards or project requirements. Finally, the client needed a reliable supplier who could provide timely technical support, sample verification, and fast delivery to avoid project delays.

Before cooperating with us, the client had considered several cable suppliers but was unsatisfied. Some suppliers could not provide the required international certifications, while others failed to offer sample testing services, making it impossible for the client to verify product quality in advance. Additionally, many suppliers had no experience in similar large-scale solar projects, leading the client to doubt their ability to meet the project’s strict requirements. When the client contacted Dongguan GERITEL Electrical, they emphasized that product quality, certification, delivery speed, and project experience were their top priorities.

2. Tailored Cables for Morocco’s Solar Park Needs

After in-depth communication with the client and a detailed analysis of the project’s requirements, our team designed a customized cable solution centered on three core cable models:H1Z2Z2-K Solar Cable, H07V-K, and PVO7AC-F Cable. We focused on solving the client’s pain points by leveraging our product advantages, project experience, and professional services.

First, we recommended H1Z2Z2-K Solar Cable for the PV module connection and DC transmission part of the project. This model is specifically designed for solar energy systems and has significant advantages over ordinary cables. Unlike standard PV cables, H1Z2Z2-K Solar Cable uses halogen-free flame-retardant insulation and sheath materials, which are resistant to high temperatures, UV radiation, and chemical corrosion—critical for withstanding Morocco’s desert environment. It complies with the EN 50618:2014 standard and holds TUV, and IEC certifications, ensuring it meets international quality and safety requirements. For this project, we provided multiple specifications of H1Z2Z2-K Solar Cable, including the key specification 1×6 mm H1Z2Z2-K Solar Cable, as well as 1×4 mm, 2×4 mm, and 2 x6 mm sizes. The 1×6 mm specification was mainly used for the connection between PV modules and combiner boxes, thanks to its excellent current-carrying capacity and flexibility, which simplifies on-site installation in the desert.

Second, we selected H07V-K for the project’s low-voltage control system and indoor wiring. This single-core flexible cable is ideal for fixed installations, with a rated voltage of 450/750 V and a temperature range of -30°C to +70°C, making it suitable for both indoor and outdoor low-voltage applications. Compared to other low-voltage cables, H07V-K uses high-quality class 5 multi-stranded copper conductors, which have lower resistance and better conductivity, reducing energy loss. It also features PVC insulation that is wear-resistant and easy to strip, improving construction efficiency. We supplied H07V-K in specifications of 1×16 mm², 1×25 mm², 1×35 mm², and 1×50 mm², totaling 80,000 meters, to meet the wiring needs of the project’s control cabinets, lighting systems, and signal circuits.

Third, we provided PVO7AC-F Cable for the AC transmission part of the project, connecting inverters to step-up transformers and the grid. This multi-core AC solar cable is designed for high-efficiency power transmission in solar systems, with a rated voltage of 450/750 V and a service life of over 25 years—matching the 25-year design life of the Noor Solar Park. Unlike single-core AC cables, PVO7AC-F Cable is available in 2-core, 3-core, and 5-core specifications, which reduce wiring complexity and save installation time. For this project, we supplied 3-core 6 mm², 3-core 10 mm², and 5-core 4 mm² PVO7AC-F Cable, totaling 50,000 meters. The cable uses irradiation cross-linked compounds, ensuring high resistance to UV, ozone, and hydrolysis, and its tinned copper conductors enhance corrosion resistance in the desert’s dry and dusty environment.

To address the client’s doubt about product quality, we offered free sample services for all three cable models. We sent 5-meter samples of each specification to the client’s laboratory, allowing them to test key performance indicators such as temperature resistance, UV resistance, and conductivity. Our team also provided detailed technical parameters and certification documents, including TUV and RoHS certifications, to prove the product’s compliance with international standards. Additionally, we shared our experience in similar solar projects in other countries, such as a 100 MW solar park in Greece and a 80 MW solar project in PNG, which further enhanced the client’s confidence in our capabilities.

3. Certifications and Strict Quality Control

Safety is the top priority for large-scale solar projects, and our cables are designed to provide maximum safety protection. All cables supplied for the Noor Solar Park project hold international certifications that are widely recognized in the renewable energy industry. The H1Z2Z2-K Solar Cable and PVO7AC-F Cable have passed TUV certification, which includes rigorous testing for UV resistance, high-temperature performance, and flame retardancy.
