The Development and Prospect of Wuxi's Photovoltaic Power Stations

Introduction to Wuxi's Photovoltaic Power Stations

In recent years, Wuxi has witnessed remarkable development in the photovoltaic power station sector, which plays a crucial role in the city's pursuit of green development and the achievement of the 'dual - carbon' goals. This article will explore various aspects of Wuxi's photovoltaic power stations, including their technological innovation, application scenarios, and future prospects.

Technological Innovation in Wuxi's Photovoltaic Power Stations

The New - Type Photovoltaic Tracking System

In October 2025, Wuxi launched its first new - type photovoltaic tracking system. Developed by Wuxi Power Supply Company in collaboration with Jiguang Photovoltaic Energy Co., Ltd. and Wuxi Huasheng New Materials Technology Co., Ltd., this system represents a significant breakthrough in photovoltaic technology. Traditional fixed - bracket photovoltaic panels can only achieve maximum efficiency at the optimal inclination angle. In adverse conditions such as rainy days, weak light in the morning and evening, or when the sun's angle is skewed, their power - generation efficiency drops significantly. However, the new - type photovoltaic tracking system is equipped with a high - precision angle sensor on its dual - axis tracking bracket. This bracket can capture real - time changes in the sun's azimuth and altitude angle, ensuring that the photovoltaic panels are always in the best light - receiving state, thus maximizing the absorption of irradiance energy.

In terms of material selection, the research team combined perovskite materials with low - loss heterojunction stacks. This combination allows the photovoltaic panels to absorb different wavelengths of light in segments, effectively reducing thermal losses caused by photon - energy mismatch. The low - loss heterojunction stack has an optoelectronic conversion efficiency of over 33%, far exceeding the level of traditional crystalline silicon components. Moreover, the bracket is made of magnesium - alloy - coated steel, which has 5 to 10 times better corrosion resistance than galvanized steel and is suitable for various terrains and multiple component types.

Since its operation, the new - type photovoltaic tracking system has an average daily power generation of 7.6 kilowatt - hours and can maintain a power - generation efficiency of over 20% even on rainy days, effectively solving the problem of insufficient power - generation efficiency in low - light environments.

Application Scenarios of Wuxi's Photovoltaic Power Stations

Industrial Park Applications

Wuxi Star Island Industrial Park is a national first - batch distributed photovoltaic demonstration park. It started building photovoltaic power stations in 2013. As of now, the total installed capacity of photovoltaic power in the park has exceeded 15 megawatts, with an annual power generation of over 18 million kilowatt - hours. This accounts for 16% of the park's daily electricity load, saving 5,040 tons of standard coal and reducing nearly 14,000 tons of carbon dioxide emissions annually.

The park's power - distribution network consists of external power supply, photovoltaic power generation, and energy - storage power stations. Photovoltaic power is first consumed by enterprises in the park. If there is surplus power, it is absorbed by the park's power grid. In addition, a 20 - megawatt power and 160 - megawatt - hour rated energy - storage power station was built using two idle dormitory buildings in the park. This energy - storage power station can charge at night and discharge during the day, reducing the power demand during peak hours through 'peak shaving and valley filling' and improving the economic efficiency of the park's power grid.

Residential Applications

In Wuxi, more and more residents are participating in the photovoltaic power - generation trend. Mr. Zhao, the first household in Wuxi to install a distributed photovoltaic power - generation system, installed a 5 - kilowatt 'mini - power station' on the roof of his two - story building. In the first year, his family generated 6,168 kilowatt - hours of electricity. They used 1,268 kilowatt - hours themselves, and the remaining 4,900 kilowatt - hours were sold to the national power grid through the 'excess - power - on - grid' model, earning an annual income of 5,000 yuan.

Contribution to the 'Dual - Carbon' Goals

Reduction of Carbon Emissions

Wuxi's distributed photovoltaic power stations have made significant contributions to carbon - emission reduction. The city's distributed photovoltaic power has an annual power generation of 10.72 billion kilowatt - hours, with a 100% consumption rate. It is estimated that this can reduce carbon - dioxide emissions by 1.0688 million tons annually, equivalent to the annual emissions of 510,000 fuel - powered vehicles.

Promotion of Green Development

In a situation where Wuxi's sunlight resources are not highly advantageous (it belongs to the third - class sunlight area in China, with a photovoltaic annual power - generation utilization hour of 1,100 hours, ranking in the lower - middle level nationwide), the fact that its distributed photovoltaic installed capacity ranks first in the province indicates that green development has become a social consensus. The development of photovoltaic power stations in Wuxi is in line with the national 'dual - carbon' goals and promotes the transformation of the energy structure towards a more sustainable and low - carbon direction.

Challenges and Solutions in the Development of Photovoltaic Power Stations

Challenges

One of the main challenges is the instability of power supply caused by large - scale and disordered access of distributed photovoltaic power to the local power grid. This can lead to problems such as power - supply instability on the power - source side, line overload, and reverse - power - transmission accidents. In addition, the intermittent nature of photovoltaic power generation, affected by weather and time, also poses challenges to the stable operation of the power grid.

Solutions

The 'Green Energy E - Station' of Skyworth Photovoltaic provides a solution. It features a 'light - storage - charging - cloud' integration, suitable for various photovoltaic - power - station construction scenarios. It adopts a centralized development model with high - and low - voltage coordinated grid connection and introduces an energy - storage system to solve the problem of photovoltaic power consumption nearby. Through the cloud - storage intelligent control system, it realizes the efficient and systematic management and stable operation of power - station energy, leading the digital development of the source - network - load - storage system.

The Complete Industrial Chain of Wuxi's Photovoltaic Industry

From Production to Operation

Wuxi has formed a complete and resilient photovoltaic industry chain, covering from silicon wafers, batteries, and components to power - station development and operation and maintenance. In the industrial parks of Wuxi, workshops are producing inverters, the 'heart' of photovoltaic power stations, and production lines are manufacturing 'industrial mother machines' for top - tier global photovoltaic enterprises.

Industrial Agglomeration

As of 2025, Wuxi has 321 new - energy scale - above enterprises. From January to September 2025, these enterprises achieved an industrial output value of 180.505 billion yuan, indicating strong industrial innovation momentum. The agglomeration of these enterprises has promoted the overall development of the photovoltaic industry in Wuxi.
