Israel Ship Photovoltaic System Wire Export

In early 2022, we partnered with an Israeli marine engineering company specializing in offshore vessel upgrades to provide a comprehensive wire solution for their ship photovoltaic system project. As the global shipping industry shifts toward green energy transformation, more vessels are installing PV systems to reduce fuel consumption and carbon emissions. However, marine environments pose unique challenges for wiring, and the Israeli client faced multiple pain points that threatened the project’s progress—until our team stepped in with tailored solutions, reliable products, and efficient execution.

1. The Israeli Client’s Marine PV Wiring Dilemma

The client, a leading marine engineering firm based in Haifa, Israel, was tasked with upgrading the PV systems of 8 offshore cargo vessels. Their goal was to integrate solar power into the vessels’ auxiliary power systems, cutting reliance on diesel generators and lowering operational costs. The project required wires that could withstand the harsh marine environment—high humidity, salt spray, extreme temperature fluctuations, and constant vibration—while meeting Israel’s strict electrical safety standards and international marine certifications.

Before contacting us, the client had struggled with two key issues. First, they could not find a single supplier that offered all the required wire types, forcing them to coordinate with multiple vendors, which led to delays and inconsistent product quality. Second, the wires they initially tested failed to meet the marine environment’s durability requirements—some standard wires corroded quickly after exposure to salt spray, while others could not withstand the vessels’ vibration, leading to frequent short circuits.

Additionally, the client needed a supplier with experience in marine PV projects, as standard industrial wires are not designed for the unique demands of shipboard use. They also required a fast delivery to meet their tight project timeline, as any delay would result in additional docking costs and missed operational deadlines. After researching global wire exporters, they chose Dongguan Greater Wire & Cable Co., Ltd. for our proven track record in marine renewable energy projects, comprehensive product range, and international certification advantages.

2. Matching the Right Wires to Marine PV Needs

After detailed communication with the client, our engineering team analyzed the project’s specific requirements—including the PV system’s power output, installation locations (deck, engine room, and control cabin), and environmental conditions—and designed a customized wire solution centered on three core products: PV1-F cable, H05VV-F, and NYM-J. Each product was selected for its unique advantages, addressing the client’s pain points and outperforming alternative options.

The PV1-F cable was chosen as the core wiring for the PV panels, responsible for transmitting DC power from the panels to the inverter. Unlike standard solar cables, our PV1-F cable features XLPO insulation and a tinned copper conductor, which provides excellent resistance to UV radiation, salt spray, and high temperatures. For this project, we supplied multiple sizes of PV1-F cable, including the key 1x6mm PV1-F, along with 1x4mm and 1x10mm variants, totaling 12,000 meters. The 1x6mm PV1-F was specifically used for the main power transmission lines between the PV arrays and the inverter, as its 6mm cross-section ensures stable current transmission with minimal energy loss, making it ideal for the vessels’ medium-power PV systems. Compared to conventional PV cables, our PV1-F cable also has a bending radius of 6×d, allowing for easy installation in the limited space of ship decks and cabins.

For the auxiliary power lines in the engine room and control cabin, we recommendedH05VV-F flexible cables. Available in sizes 1x1.5mm², 2x1.5mm², and 3x2.5mm² (total 8,500 meters), this cable is designed for flexible installation in tight spaces, with a PVC insulation and sheath that resists oil, chemicals, and mechanical damage—critical for the engine room’s harsh environment. Unlike rigid cables, H05VV-F’s flexibility allows it to withstand the vessels’ constant vibration without cracking, solving the client’s earlier issue of short circuits caused by vibration. It also meets the low smoke zero halogen (LSZH) standard, ensuring safety in case of fire, which is a mandatory requirement for marine applications.

For the indoor control lines in the vessel’s bridge and control cabin, we provided NYM-J solid-core cables in sizes 1x2.5mm² and 2x2.5mm² (total 5,000 meters). NYM-J cables feature a multi-core structure with PVC insulation and a protective sheath, offering superior electrical insulation and resistance to humidity—perfect for the controlled but humid indoor environment of the ship. Compared to flexible cables, NYM-J’s solid core provides more stable signal transmission, ensuring the PV system’s control panel operates accurately. The client initially considered using standard indoor cables, but we explained that NYM-J’s marine-grade insulation is specifically designed to resist the salt-laden humidity on ships, which standard cables cannot handle.

Our solution’s key advantage was its comprehensiveness—we supplied all three wire types, eliminating the client’s need to work with multiple suppliers. We also tailored the wire lengths and sizes to each vessel’s specific PV system layout, reducing waste and ensuring a perfect fit for the installation.

3. International Certifications for Marine Reliability

For marine projects in Israel, compliance with international safety standards is non-negotiable, and our products’ certifications were a key factor in the client’s decision. All wires supplied for this project hold authoritative international certifications, including CE and TUV, which are mandatory for entering the European and Israeli markets.

Our PV1-F cable is certified by TUV and meets IEC 62930/EN 50618 standards, confirming its durability and safety for marine PV applications. The TUV certification ensures that the cable has passed rigorous independent testing, including resistance to salt spray, UV radiation, and temperature extremes, making it suitable for long-term use in offshore environments. The CE certification, meanwhile, guarantees that the cable complies with EU safety, health, and environmental protection directives, allowing for seamless import into Israel without additional testing.

The H05VV-F and NYM-J cables also hold CE and TUV certifications, along with ROHS compliance, ensuring they are free of hazardous materials and safe for both the environment and ship personnel. Additionally, all our cables undergo strict quality control checks during production, including insulation resistance testing, conductor resistance testing, and mechanical strength testing, to ensure zero defects before delivery. This commitment to quality gave the client confidence that the wires would perform reliably in the harsh marine environment, reducing the risk of system failures and maintenance costs.

4. Fast and Efficient to Meet Tight Deadlines

The client emphasized the need for fast delivery, as any delay would extend the vessels’ docking time and increase operational costs. Leveraging our advanced production facilities and efficient supply chain management—we use high-precision automatic production equipment to minimize production errors and speed up manufacturing—we completed the production of all 25,500 meters of wire in record time. We prioritized the project to ensure that the wires were manufactured, tested, and packaged within a short timeframe, far exceeding the client’s expectations.

Our team also handled all export logistics, including customs clearance and documentation, to ensure a smooth delivery to Haifa Port in Israel. We worked closely with reliable shipping partners to minimize transit time, and the entire shipment arrived well ahead of the client’s project schedule. This fast execution allowed the client to start the PV system installation on time, avoiding costly delays and ensuring the vessels returned to operation as planned.

5. Reliable Performance and Tangible Value

After the installation was completed in mid-2022, the client’s ship PV systems have been operating stably for months, with zero wire-related failures. The PV1-F cable (including the 1x6mm PV1-F) has efficiently transmitted solar power with minimal energy loss, while the H05VV-F and NYM-J cables have withstood the marine environment’s challenges—no corrosion, cracking, or short circuits have been reported.

The client has achieved significant operational benefits from the project: each vessel’s diesel consumption has been reduced by 15%, lowering operational costs and carbon emissions. The reliable wiring solution has also reduced maintenance requirements, as the cables’ durability means fewer replacements and repairs. Additionally, the client’s reputation in the Israeli marine industry has been enhanced, as they are now able to offer green energy upgrades with proven reliability.
