In Dayton, Texas, USA, the Liberty energy project combines a 72-megawatt photovoltaic power station with a 60-megawatt battery storage system to provide 100% renewable electricity to BASF's Freeport site. This project not only meets the electricity needs of large industrial facilities but also gives back to the local community through initiatives such as community gardens and the construction of nature conservation trails.

At the same time, in the deep mountains of Xiushan, Chongqing, the integrated wind and solar energy storage system of villager Cui Defang's family is operating stably. This system can store up to 50 kilowatt-hours of electricity, ensuring about 10 days of power consumption for users, effectively solving the problem of unstable power supply in remote mountainous areas.

From developed countries to rural China, "photovoltaics + energy storage" is becoming an important driver of energy transition and rural revitalization, bringing multiple economic, environmental, and social benefits to rural areas.

The energy challenges faced by traditional rural areas are complex and diverse. In remote areas such as Xiushan in Chongqing, due to the complicated geographical environment and the distance from the main power grid, the expansion of conventional power grids faces numerous issues, including huge investment, long construction periods, and unstable power supply quality.

The reliability of power supply is the primary challenge. In mountainous areas, the voltage at the end of the power grid is low and unstable. During peak electricity usage periods, voltage drops and appliances often cannot be used normally. In addition, the high cost of electricity also restricts rural development. With the advancement of agricultural mechanization and industrialization, the proportion of electricity expenses in production costs is increasing year by year.

Extreme weather threats further exacerbate the energy supply issues in rural areas. Natural disasters such as heavy snow and ice storms can easily lead to power outages in rural power grids, and the repair and restoration process takes time, severely impacting the lives of villagers and agricultural production.

The innovative combination of "photovoltaics + energy storage" provides a comprehensive solution to rural energy issues.

In terms of stable power supply, energy storage systems can respond to voltage fluctuations in milliseconds, quickly charge and discharge, and effectively smooth out voltage fluctuations. By reasonably configuring photovoltaic, wind power generation equipment, and energy storage devices, the complementary and collaborative operation of multiple energy sources is achieved, significantly improving the stability and reliability of power supply in remote areas.

In terms of economic benefits, through the "self-use and surplus electricity online" model, farmers can not only save on electricity costs but also earn income from selling electricity. The "solar storage charging" integrated parking lot project in Shigu Community, Nancheng, Dongguan, has laid approximately 12,000 square meters of photovoltaic carports in the parking lot, along with supporting energy storage equipment. The annual power generation is expected to exceed 3 million kilowatt-hours, alleviating parking pressure in the community while providing residents with high-quality charging service guarantees.

In terms of emergency backup power, energy storage systems can automatically switch to off-grid mode, providing power for several hours to several days. The Calistoga Resilience Center project in California, USA, integrates hydrogen fuel cell and lithium battery technology, capable of providing at least 48 hours of continuous energy supply, ensuring power supply to the community during public safety power shutoff events.

The value of "photovoltaics + energy storage" is becoming evident in various fields in rural areas.

In the field of agricultural production, this combination provides stable power for modern agricultural facilities. The Texas Liberty project supplies 48 megawatts of power to the BASF Freeport site through a 12-year power purchase agreement, supporting the energy needs of its integrated production model.

In terms of power supply in remote areas, this system plays an irreplaceable role. The case of Xiushan, Chongqing shows that the wind-solar energy storage complementary system combines two power generation methods: wind power and photovoltaic, generating and storing electricity together. The equipment is easy to install and transport, and the power generation is clean and pollution-free, effectively solving the electricity problem for residents deep in the mountains.

In terms of community services, the integrated solar storage project is creating new community value. Dongguan's "super parking lot" not only provides parking and charging services but also plans to add convenient facilities such as smart car washes and energy stations, offering a "parking + charging + service" integrated space that directly addresses the pain points of parking difficulties and charging challenges in urban villages.

The "photovoltaic + energy storage" not only brings about an energy revolution but also serves as a comprehensive driving force for rural revitalization.

From the perspective of economic benefits, rural communities have gained tangible profits through saving electricity costs and increasing revenue from electricity sales. The Dongguan "light-storage-charging" integrated parking lot project is expected to generate over 3 million kilowatt-hours of electricity annually, which can reduce carbon emissions by more than 1,000 tons each year.

In terms of ecological benefits, every village that installs a solar storage system has become a participant in carbon reduction actions. The Kidston Gold Mine transformation project in Australia turns abandoned mine pits into a pumped storage power generation system, combined with a 50-megawatt solar power plant, which can supply electricity for approximately 27,600 households.

More importantly, the social benefits. The popularization of clean energy has improved the living environment in rural areas and injected new vitality into rural revitalization. The Liberty project in Dezhou supports local community development in multiple ways through community and nature programs, creating community gardens, repairing drainage systems, and recruiting volunteers for meal delivery services.

With the continuous advancement of photovoltaic and energy storage technologies and the ongoing decrease in costs, "photovoltaic + energy storage" will play an increasingly important role in rural revitalization.

Technological innovation will drive continuous improvements in system efficiency. The Calistoga project in California, USA, innovatively integrates hydrogen fuel cell and lithium battery technologies, achieving black start, grid formation, and coordinated energy dispatch through the VaultOS™ energy management system, providing the community with multi-day long-duration energy storage solutions.

The application scenarios will continue to expand. From the photovoltaic power station on the dam wall of Lake Muotathal in Switzerland to the 2GWh gravity energy storage project being planned by Genex in Australia, these innovative practices provide more possibilities for energy solutions in rural areas.

Policy support is also an important force driving the implementation of solar storage projects in rural areas. More and more countries and regions are realizing the importance of clean energy for rural development and are encouraging its application in rural areas through various measures.
