Voltage "soars"! 2000V high-voltage components are becoming the trend!

As a key technological path for enhancing the value and efficiency of photovoltaic projects, 2000V modules, with their multiple advantages of system optimization, cost control, and performance leap, are becoming the preferred solution for large-scale ground-mounted Power Plants and distributed scenarios.

As the world's first operational 2000V project, the Mengjiawan 182MW project partially utilizes 2000V modules and has been operating stably for two years, demonstrating excellent power generation performance. This showcases the powerful driving force of high-voltage technology on the green transformation of the photovoltaic industry.

1. High Voltage Becomes an Inevitable Industry Trend: Synergistic Breakthroughs from Technological Optimization to Cost Control

In the current pursuit of cost reduction and efficiency improvement in the photovoltaic industry, increasing system voltage has become an industry consensus.

The reason why high-voltage battery modules have become an inevitable development lies in their ability to create a synergistic effect across the entire chain, from system design to cost control. High system voltage supports larger-scale series and parallel module designs, directly reducing the number of inverters used, simplifying the system structure, reducing equipment procurement costs, and decreasing the complexity and manpower required for later operation and maintenance.

With the popularization of large-size, high-power modules, high-voltage technology effectively solves the current loss problem caused by power increases. According to circuit principles, when the transmitted power is constant, voltage and current are inversely proportional. This characteristic significantly reduces the current-carrying capacity of cables, allowing for the use of cables with smaller cross-sectional areas and reducing the consumption of conductive materials such as copper and aluminum.

Simultaneously, the reduced weight of cables during transport and shorter installation time further lower laying costs. In this positive cycle of technological optimization, cost reduction, and efficiency improvement, the 2000V system occupies a key position in the large-scale development of photovoltaics, especially meeting the core requirements of large-scale ground-mounted power plants for high cost and efficiency.

2. Breaking Through Technological Barriers to Create the "Core Strength" of High-Voltage Modules

The 2000V ultra-high system voltage Solar Panels has built a differentiated competitive advantage through technological integration and innovation. Its core breakthrough lies in the combination of 2000V ultra-high system voltage and high volume resistivity double-glass encapsulation technology, achieving a comprehensive leap in insulation performance, operational stability, and system compatibility.

In terms of insulation safety, the product optimizes the module layout, raising the insulation level to an internationally leading level. By improving the internal circuit design of the modules and introducing TÜV-certified high-insulation connectors, the key indicators such as leakage current and withstand voltage of the modules meet the highest IEC standards under 2000VDC high-voltage conditions, completely eliminating safety hazards in high-voltage scenarios.

In terms of long-term stability, the modules exhibit excellent weather resistance and corrosion resistance, ensuring stable operation for 25 years even in complex environments such as extreme temperature ranges and high humidity.

The 2000V system architecture directly promotes improved power plant efficiency by reducing the number of inverters, combiner boxes, and other electrical equipment, lowering initial investment costs, reducing equipment failure points, and improving system reliability. Simultaneously, lower current transmission losses effectively improve system power generation efficiency, further optimizing LCOE.

3. The First 2000V Demonstration Benchmark Empowers Green Energy Transformation

The Mengjiawan 182MW photovoltaic project has become the first global model for the large-scale application of 2000V modules. The project boasts a DC-side installed capacity of 182MW. Its innovative feature is the adoption of the industry's first 2000V Photovoltaic Modules, showcasing the comprehensive advantages of high-voltage technology from design and construction to grid connection.

In terms of economics, the 2000V system design offers significant advantages, increasing the installed capacity of a single module string by over 30%. Calculations indicate that the Mengjiawan project will generate an average of approximately 298.87 million kWh of electricity annually over its 25-year operating period, with an equivalent full-load operating time of 1640 hours per year, exceeding the industry average for projects of similar scale. The project will reduce carbon dioxide emissions by approximately 278,000 tons annually and save approximately 94,100 tons of standard coal, equivalent to the ecological benefits of planting approximately 1.54 million trees, injecting green momentum into local desertification control, ecological restoration, and energy structure transformation.

The application of 2000V modules not only solves the cost control challenges of large-scale power plants but also ensures long-term benefits through efficiency improvements, providing replicable experience for the subsequent promotion of high-voltage technology in more projects.
