1. Challenges of Floating Solar Plant Renovation in the Philippines

The floating solar power plant on Laguna Lake is a key renewable energy project in the Philippines, contributing significantly to the local power grid and supporting the country’s carbon neutrality goals. However, after years of operation in a harsh aquatic environment—exposed to high humidity, strong UV radiation, and occasional water splashes—the plant’s original cable system had deteriorated severely. The client, a professional renewable energy project operator, was facing several critical challenges that threatened the plant’s operational safety and efficiency.

First, the original cables lacked resistance to the lake’s humid environment, leading to frequent insulation damage and short circuits. This not only disrupted power generation but also increased maintenance costs and safety risks. Second, the client struggled to find a single supplier that could provide all the required cable types, as the project needed a combination of medium-voltage cables, low-voltage wires, and photovoltaic cables—each with specific specifications to meet different operational needs. Sourcing from multiple suppliers would cause delays, inconsistent quality, and complicated logistics, which was unacceptable given the project’s tight timeline.

Third, the client required cables that met international standards and local certifications to ensure compliance with Philippine regulations. The Philippines mandates that electrical products, including cables, must obtain BPS (Bureau of Philippine Standards) certification, and failure to meet these requirements would result in customs detention or project delays. Additionally, the client prioritized fast delivery, as any downtime in the plant would lead to significant revenue losses. They needed a supplier that could deliver high-quality, certified cables in the shortest possible time to minimize disruption.

After researching multiple cable exporters, the client chose us for our comprehensive product range, proven track record in renewable energy projects, and strong certification support—factors that directly addressed their core pain points.

After in-depth communication with the client, our technical team analyzed the project’s specific needs and designed a customized cable solution that included three core product lines: MV-90 (American standard), H07V-K wires, and photovoltaic cables. Each product was selected for its unique advantages, ensuring it was perfectly suited for the floating solar environment and the project’s operational requirements.

2.1 MV-90 Medium-Voltage Cable

For the plant’s medium-voltage power transmission system, we recommended the MV-90 American standard cable, which is specifically designed for harsh industrial and renewable energy environments. The client chose two key specifications: 1/0 AWG and 2/0 AWG, with a total order quantity of 15,000 meters.

The MV-90 cable includes a corrugated copper shield that prevents moisture penetration, a key advantage over standard cables that often fail due to water ingress in aquatic environments. Additionally, it meets ANSI/UL standards and holds BPS certification, ensuring full compliance with Philippine regulations. The client chose the MV-90 over other options because of its durability in humid conditions and its ability to maintain stable performance even with long-term exposure to UV radiation and water splashes.

2.2 H07V-K Low-Voltage Wires

For the plant’s low-voltage control and distribution system, we supplied H07V-K wires, a European standard flexible cable that is ideal for fixed electrical installations in industrial settings. The client ordered four specifications: 1x16mm², 1x35mm², 1x50mm², and 1x95mm², with a total quantity of 35,000 meters. The H07V-K wire features a class 5 fine-twisted copper conductor, making it highly flexible and easy to install in the tight spaces of the floating solar panels and control cabinets.

Compared to ordinary PVC wires, the H07V-K has a higher rated voltage (450/750V) and better flame retardancy, meeting IEC 60332-1 standards. Its PVC insulation is resistant to moisture and UV radiation, ensuring long service life in the lake’s harsh environment. The client selected the H07V-K because of its flexibility, durability, and compatibility with the plant’s existing low-voltage system, eliminating the need for costly modifications.

2.3 Photovoltaic Cables

For the connection between solar panels and inverters, we provided high-performance photovoltaic cables in four specifications: 1x4mm², 1x6mm², 2x4mm², and 2x6mm², with a total order quantity of 74,000 meters. These cables are specifically designed for solar energy systems, featuring cross-linked polyethylene (XLPE) insulation that is resistant to UV radiation, moisture, and temperature fluctuations—key requirements for outdoor floating solar applications.
