On September 22, 2022, a groundbreaking development in photovoltaic (PV) power system standards was officially released. This new standard for 2000V DC photovoltaic power generation systems was a collaborative effort led by TÜV SÜD, Sowellsolar (Zhejiang Sowell Electric Co., Ltd), and other prominent industry players. The standard represents a significant advancement, accommodating higher voltage levels, improving safety, and enhancing system performance.

The Need for an Upgraded Standard in Photovoltaic Power Systems

As solar technology evolves, so too must the standards that ensure safe and efficient energy delivery. Traditional PV systems have largely operated on voltages of 1000V or 1500V DC. However, as PV installations scale up in size and complexity, the need for cables that can withstand higher voltages has become clear. With the release of the 2000V DC cable standard, solar systems can now operate at higher efficiencies, meeting the power demands of larger installations.

Key Highlights of the New 2000V Photovoltaic Cable Standard

The newly released standard for 2000V DC photovoltaic systems introduces several critical upgrades:

1. Expanded Voltage Range

   • The standard increases the system voltage capability from 1500V DC to 2000V DC. This upgrade allows PV systems to operate at a higher voltage, which can improve power efficiency and reduce overall system costs.

2. Increased Test Voltage

   • Test voltage requirements have risen from AC 6.5kV to AC 8.5kV. This ensures that cables meet stringent durability and safety standards, making them highly reliable even under extreme operating conditions.

3. Three Conductor Types

   • The standard specifies three different conductor materials to suit various installation requirements:
     • Tinned Copper: Known for excellent conductivity and corrosion resistance.
     • Aluminum Alloy: Lightweight, cost-effective, and suitable for high-current applications.
     • Tinned Copper Aluminum Alloy: Combines the strengths of copper and aluminum, offering durability and high performance in demanding environments.

4. Downward Compatibility

   • One of the most valuable features of the new standard is its backward compatibility. The 2000V DC cables are designed to be fully compatible with existing 1000V and 1500V systems, ensuring flexibility in installation and reducing the need for extensive system upgrades.

Advantages of the 2000V DC PV Cable Standard

This upgraded 2000V standard for photovoltaic cables provides numerous benefits for solar power systems, especially for large-scale commercial installations.

1. Improved System Efficiency

Higher voltage means that larger solar arrays can be connected with fewer cables, which reduces power loss and improves the overall efficiency of energy transmission. For PV installations, this translates to increased energy yield and, consequently, better returns on investment.

2. Enhanced Safety Standards

Raising the system and test voltage levels provides an added layer of safety, protecting against potential electrical faults or breakdowns. By adhering to this new standard, solar installations will be better equipped to handle the demands of high-voltage applications safely and effectively.

3. Versatility in Conductor Material

The inclusion of multiple conductor types allows for greater adaptability based on the installation’s specific needs. Whether in environments requiring corrosion resistance, cost efficiency, or lightweight materials, PV installers have a range of options to choose from.

4. Simplified Upgrades and Installations

Backward compatibility with 1000V and 1500V DC systems ensures that PV developers can implement the new 2000V standard without needing to replace entire systems. This flexibility is especially beneficial for expanding existing solar fields or upgrading older systems to handle higher voltages.
