This is currently the largest distributed photovoltaic power generation project in Wuxi, with a total installed capacity of 3.3 megawatts and is scheduled to be connected to the grid for power generation on the 27th of the same month, with an annual power generation of over 3 million degrees.

The Agglomeration in Wuxi New Area

Wuxi New Area was included in the first batch of national distributed photovoltaic power generation demonstration areas last year. As of 2025, six major photovoltaic power generation projects have settled in this area, including projects from Poly GCL, South Korea's OCI, South Korea's Hanwha, Shanghai Aerospace Machinery and Electronics, China National Machinery and Equipment Engineering Corporation, and Wuxi Furuisi. Moreover, foreign - funded enterprises such as Japan's Sony and the United States' Caterpillar have also contacted the new area government, expressing their willingness to provide rooftops for photovoltaic power station installation.

Potential for Further Development

There are 106 enterprises in the new area that meet the construction conditions, with a total rooftop area of 4.08 million square meters and a total potential installed capacity of about 200 megawatts. When including residential communities, schools, and service units, the total installed capacity can reach 300 megawatts. Once fully built, it can save 300 million degrees of electricity annually and reduce carbon dioxide emissions by about 300,000 tons.

The Process of Photovoltaic Installation in Wuxi

Site Selection

The first step in photovoltaic installation is to choose a suitable location. For rooftop installations, factors such as sunlight exposure time, shadow - free conditions, and the structural strength of the roof need to be considered. For ground - based installations, a flat area with sufficient sunlight, no obvious land pollution, and no obstructions is required. For example, in the Wuxi Wanyu Electronics project, the installation areas include the concrete and color - steel tile roofs of the factory buildings, as well as newly - built photovoltaic carports on open spaces.

Design

Based on the site - selection results and customer requirements, a detailed design of the photovoltaic system is carried out. This includes determining the layout of the power station, the number of components, the type of solar panels, and the capacity of the system. Professional designers will calculate and plan to ensure that the system can achieve the best power - generation efficiency.

Procurement

After the design is completed, the necessary equipment such as photovoltaic modules, inverters, and brackets need to be purchased. High - quality equipment is crucial for the long - term stable operation of the photovoltaic system. Suppliers should be carefully selected to ensure the quality and performance of the equipment.

Bracket Installation

Brackets are used to support the solar panels. For rooftop installations, roof - type brackets that match the roof structure are selected, while for ground - based installations, ground - type brackets are used. The installation of brackets must be firm to ensure the stability of the photovoltaic components. Special attention should be paid to the installation angle and orientation of the brackets to maximize sunlight capture.

Component Installation

Photovoltaic components are installed on the brackets using professional tools and techniques. During the installation process, the alignment and connection of the components need to be ensured to avoid issues such as poor contact. Each component should be securely fixed to prevent damage caused by wind, rain, or other external factors.

Wiring

The wires between the photovoltaic components and the inverter are connected to ensure the smooth flow of current. The inverter converts the direct current generated by the solar panels into alternating current, which can be used in the household grid or stored in a battery energy - storage system. Correct wiring is essential for the normal operation of the photovoltaic system.

System Debugging

After the installation is completed, a comprehensive system debugging is carried out. This includes testing the power - generation performance of the photovoltaic system, adjusting relevant parameters, and checking for any potential safety hazards. Only after passing the debugging can the photovoltaic system be put into normal operation.

Cost and Subsidy Policies in Wuxi

Installation Cost

The cost of photovoltaic installation in Wuxi varies depending on the project scale and complexity. Previously, the installation cost of a distributed photovoltaic power station was about 40,000 to 60,000 RMB, and it took 8 to 10 years to recover the investment cost. However, with technological progress and cost reduction, the actual installation cost may have changed.

Subsidy Policies

The Wuxi government has introduced a series of subsidy policies to promote the large - scale development and application of photovoltaic power generation. During the 14th Five - Year Plan period, Wuxi aims to add 1185 MW of photovoltaic capacity, with a striving target of 1683 MW. For example, photovoltaic projects with a local product rate of over 50% in Wuxi New Area can receive a one - time subsidy of 200,000 RMB per megawatt of installed capacity. Enterprises that provide rooftop resources for distributed photovoltaic power station construction will be given priority in enjoying various energy - saving and consumption - reduction support policies. In addition, there are subsidies for the initial installation of photovoltaic carports (0.5 yuan/W), photovoltaic + energy - storage projects (0.2 yuan/W), and a power - generation subsidy of 0.15 yuan/kWh for three years.

The Advantages of Photovoltaic Installation in Wuxi

Photovoltaic systems can convert solar energy into electrical energy, reducing the dependence on traditional energy sources such as coal and oil. This helps to reduce carbon dioxide emissions and other pollutants, contributing to environmental protection and sustainable development. For example, the large - scale installation of photovoltaic systems in Wuxi can significantly reduce the city's carbon footprint.

Economic Benefits

Homeowners and businesses can not only meet their own electricity needs through photovoltaic power generation but also sell the excess electricity to the grid, obtaining additional economic income. Moreover, with the government's subsidy policies, the pay - back period of the investment in photovoltaic installation can be shortened, increasing the economic attractiveness of photovoltaic projects.

Energy Independence

Photovoltaic systems provide a certain degree of energy independence. In case of power grid failures or power shortages, photovoltaic - powered facilities can still operate normally, ensuring a stable power supply. This is particularly important for some key facilities and industries.
