In recent years, the European balcony photovoltaic market has experienced explosive growth, not only injecting new momentum into Europe's energy transition but also presenting new market opportunities for Chinese enterprises.

I. Development Trend of European Balcony Photovoltaic and Opportunities for Chinese Enterprises

In recent years, European countries have introduced policies to strongly support the development of balcony photovoltaic. Taking Germany as an example, the government amended laws to allow apartment owners and tenants to install photovoltaic systems on their balconies, a policy that significantly boosted the installation of balcony photovoltaic in Germany. Data shows that in 2023, Germany's newly added photovoltaic installations exceeded 56GW, with a significant proportion from balcony photovoltaic. It is expected that by 2030, Germany's target for newly added photovoltaic installations will reach 600GW.
Countries such as Austria and Belgium have also introduced policies to simplify installation processes, driving a surge in household photovoltaic installations. According to Ember, a global energy think tank, in 2023, renewable energy generation accounted for more than 30% of global total electricity generation for the first time.
Although the European Union has introduced the "European Solar Charter" to support local manufacturing, currently, about 97% of photovoltaic components in Europe still rely on imports from China. Chinese enterprises have already captured 70% of the European market share in supporting equipment such as inverters and energy storage systems. As a core device for data collection in photovoltaic systems, smart meters see their demand grow in tandem with the proliferation of distributed energy. Chinese manufacturers, leveraging their cost advantages and technical adaptability, are poised to further penetrate the European market.

II. Trends in Chinese Smart Meter Demand and Technological Upgrading
With the boom in the European balcony photovoltaic market, the demand for Chinese smart meters has also seen new growth points. The development of distributed photovoltaic in China aligns closely with European market demands, driving technological upgrades and market expansion in smart meters.
Compared to traditional meters, smart meters feature remote reading, real-time monitoring, data analysis, and two-way communication, effectively enhancing grid operation efficiency, reducing operational costs, and promoting energy conservation and emissions reduction.
The success of Chinese enterprises in the European market indicates a continuous increase in the market share of smart meters. Policy support and technological upgrading in the domestic market have led to a sustained growth in smart meter demand. In 2023, China's smart meter export volume reached 10.3 billion yuan, a year-on-year increase of 17.8%, with Europe accounting for 36% of the market. It is projected that by 2025, China's smart meter market size will account for more than one-third of the global market.
Moreover, the success of the European market has provided valuable references for the technological upgrading of Chinese smart meters. For example, smart meters with remote monitoring and two-way measurement capabilities are widely used in China's distributed photovoltaic projects.
In the next five years, the rapid development of new industries such as new energy and electric vehicles will further increase the demand for smart meters. It is expected that by 2025, China's smart meter deployment will reach 300 million units, with the market size continuing to expand.
