The Competitive Landscape of Integrated Solar Storage and Charging Solutions: Dominance and Disruption in the Energy Market

Competitive Landscape of Solar Storage and Charging: Leading Companies Stranglehold and Cross-Industry Incursions

As the name implies, the integration of solar power generation, energy storage systems, and charging facilities transforms into a large-scale charging station. In recent years, the extensive development of photovoltaic and energy storage technologies, along with the rise of electric vehicles, has led to widespread discussion of this model, attracting a growing number of participants.

Why are companies optimistic about the solar storage and charging integration industry? The core logic behind this optimism lies in its deep alignment with the dual trends of energy and transportation revolutions. Through technological innovation and the restructuring of business models, this sector opens up a trillion-yuan market space.

Policy Incentives: China’s dual carbon goals clearly demand that by 2030, non-fossil energy consumption should account for 25% of total energy consumption. The solar storage and charging integration model is a crucial path to achieving this target. In fact, as early as 2020, the State Council issued the “New Energy Vehicle Industry Development Plan (2021-2035),” which called for coordinated dispatching of energy utilization for new energy vehicles alongside wind and solar power generation, promoting the construction of multifunctional integrated stations for solar storage and charging.

In recent years, the establishment of solar storage and charging integration stations has been supported by various local government subsidies. For example, Jiangsu and Guangdong have introduced “new energy + storage” subsidy policies, with Suzhou offering a subsidy of 0.15 yuan/kWh for user-side storage projects, with a maximum of 3 million yuan per project. Areas like Shanghai and Zhejiang have included solar storage and charging in their new infrastructure initiatives, benefiting from expedited land approval processes.

Market Demand: The explosive growth of electric vehicles is driving the construction of solar storage and charging integration stations. According to the latest statistics from the Ministry of Public Security, by the end of 2024, the number of new energy vehicles in the country is expected to reach 31.4 million, significantly increasing the demand for charging and placing immense pressure on the power grid’s peak load. Solar storage and charging integration can smooth out load fluctuations; for instance, the “solar storage charging inspection” super charging station built by Telda in Changzhou services over 500 vehicles daily while reducing distribution capacity demand by 30%. Moreover, 60% of China’s distribution networks face capacity shortages, particularly in rural areas. Solar storage and charging integration can establish microgrids near load centers to meet grid upgrade needs.

Technological Breakthroughs: Energy storage technology has achieved significant advancements, with lithium iron phosphate battery costs dropping to 0.6 yuan/Wh and cycle life exceeding 12,000 times. Huawei has developed a sodium-ion battery storage system that offers a cost per kilowatt-hour 15% lower than lithium batteries, successfully validated in Tibet’s weak power grid environment. AI predictions for photovoltaic power generation have achieved 95% accuracy, dynamically adjusting energy storage charging and discharging strategies, enhancing project profitability by 12%.

Economic Value: The profit sources for solar storage charging stations are diversified, including charging service fees, energy sales, grid interactions, and energy storage system operations. Solar storage charging stations can provide charging services to electric vehicle users for a fee while selling excess energy to nearby commercial and residential users. They can also interact bidirectionally with the grid, injecting surplus energy and participating in the electricity market; their energy storage systems can offer services like peak shaving and valley filling for energy dispatch.

Intense Market Competition: According to research from the QYResearch Institute, the global solar storage and charging market surpassed 65 billion yuan in 2023, with China maintaining a leading position with a 51.09% global market share. By 2025, the market size in China is projected to reach 113.424 billion yuan, indicating rapid growth. Consequently, more companies are entering this sector.

Overall, the competitive landscape of the domestic solar storage and charging integration market is characterized by a dominance of leading enterprises, the emergence of cross-industry players, and notable regional differentiation.
