Sigenergy’s Groundbreaking Solar-Storage Solution for Aquaculture

On August 25, 2025, in Hainan, China, Sigenergy, an energy innovation leader, marked a significant milestone by hosting the much-anticipated Sigenergy Day APAC. The event attracted over 300 attendees, including industry experts, clients, partners, and representatives from media outlets. The discussions focused on the latest advancements in solar-storage integration in renewable energy. This occasion stood out for not just its informative sessions but also for its practical showcase of innovative applications in aquaculture.

One highlight of Sigenergy Day was a tour of an innovative seawater fish farming project. Here, Sigenergy’s cutting-edge CI inverters and SigenStack energy storage system powered a facility boasting a remarkable integration of 6 MW of solar power with 5 MWh of energy storage. This initiative represents a groundbreaking advancement in how renewable energy can be used in unconventional sectors.

Optimizing Operational Costs in Seawater Fish Farming

The showcased aquaculture facility specializes in the cultivation of the highly sought-after Leopard Coral Grouper. It necessitates stringent environmental control to ensure the fish's survival, which entails precise regulation of water temperature, oxygen supply, and light conditions. With daily energy consumption soaring to approximately 43,200 kWh and annual usage exceeding 15 million kWh, the facility faces enormous operational expenses.

Sigenergy’s innovative solar-storage technology provides a cost-effective and ecologically sound alternative. By significantly reducing dependence on traditional power grids, the farm meets its energy needs while curtailing operational costs, opening avenues for sustainable farming.

Addressing Specific Challenges with Modular Energy Solutions

The project site presented distinct challenges that conventional energy storage systems often struggle to address. Sigenergy’s modular and adaptable approach to energy storage proved crucial in navigating these difficulties:

• - Space Constraints: Traditional bulky storage systems were impractical due to the narrow corridors of the fishponds. Sigenergy's modular solutions, featuring plug-and-play connectors, seamlessly fit into these limited spaces, capitalizing on the available land.
• - Logistical Barriers: The farm's proximity to water networks prevented heavy machinery from accessing the site. In contrast, Sigenergy's modular units facilitated swift installations without the need for cranes, with the entire system set up in only four days.
• - Foundation Integrity: The sandy soil posed potential risks of overloading foundations. Designed to evenly distribute weight, Sigenergy’s lightweight storage units ensured minimal impact on the site’s structural integrity, making them suitable for installation on less stable ground conditions.
• - Corrosion Resistance: Positioned just 300 meters from the coastline, the site faced significant risks of corrosion due to high humidity and salt exposure. Sigenergy equipped its systems with IP66 and C5-M protection ratings, guarding against the harsh coastal environment and ensuring durable long-term operation.

A Model for Sustainable Solutions

This pioneering solar-storage project not only offers the farm a reliable and economical clean energy source but also serves as a template for sustainable strategies in industries with unique energy needs. By demonstrating the practical application of solar-storage integration in challenging conditions, Sigenergy is paving the way for sustainability across various sectors and regions.

In summary, Sigenergy’s contributions to aquaculture through innovative solar-storage solutions exemplify how renewable energy can reshape unconventional industries, promoting environmental sustainability and operational efficiency. With such advancements, Sigenergy is not only transforming the energy landscape but also setting a powerful precedent for other sectors keen on sustainability.
