Aquaculture operations depend on a stable power supply, as electricity costs and power reliability directly affect daily operations. In regions with abundant solar resources, making better use of renewable energy while ensuring continuous power supply is essential for improving operational efficiency.
In Morocco, daytime solar generation does not always match nighttime electricity demand. Storing surplus solar energy and reducing grid electricity purchases became key priorities for this aquaculture project.
To address these challenges, ZETATECH delivered a 125kW/522kWh commercial and industrial (C&I) energy storage system, integrated with a 188.86kWp solar PV installation. The solution enables coordinated solar generation and battery storage, helping the customer optimize energy consumption and improve power supply reliability.
Designed for Efficient Solar-Storage Integration
The customer needed a solution that could make better use of solar generation, minimize unnecessary energy conversion losses, and provide a more reliable power supply for critical loads.
The project features the following configuration:
188.86kWp solar PV system with 266 × 710W modules
2 × 100kW MPPT solar controllers
1 × 125kW Power Conversion System (PCS)
2 × 261kWh battery cabinets
1 × 250kW Static Transfer Switch (STS)
By coordinating solar generation and battery storage, the system reduces intermediate conversion stages and improves overall energy utilization, creating a more efficient solar-storage solution for the aquaculture facility.
Solar Priority with Intelligent Energy Management
The Energy Management System (EMS) coordinates solar generation, battery storage, and grid electricity according to the site's actual energy demand.
Its operating strategy is designed to maximize solar utilization throughout the day:
Daytime: Solar power supplies the loads first, while surplus electricity is stored in the batteries.
Low solar generation: Solar power and battery storage work together to meet electricity demand.
Nighttime: The batteries discharge stored solar energy to supply the loads.
Low battery state of charge: Grid electricity provides supplementary power to maintain operation.
Through intelligent EMS dispatch, the system makes fuller use of daytime solar generation, reduces dependence on grid electricity, and helps maintain a balanced energy supply around the clock.
Built for Reliable Outdoor Operation
Aquaculture facilities have continuous electricity demands. Equipment such as water pumps and aerators needs to operate reliably, making power continuity particularly important. Meanwhile, outdoor installations may face high temperatures, dust, and humidity, placing additional demands on equipment protection and thermal management.
To address these operating conditions, the ZETATECH energy storage system adopts lithium iron phosphate (LFP) battery cells and liquid-cooling thermal management, together with an IP55 protection rating and C4 anti-corrosion design. These features enhance equipment protection and support reliable long-term outdoor operation.
Additionally, the 250kW STS enables switching between grid-connected and off-grid operation, helping maintain power supply to critical loads when grid fluctuations occur.
Lower Energy Costs, Greater Long-Term Value
By combining solar PV generation with battery storage, the project enables the aquaculture facility to use more of its locally generated solar energy and reduce electricity purchases from the grid.
Based on the project's load profile, local electricity tariffs, and operating strategy, the system is estimated to deliver annual electricity cost savings of approximately USD 60,000–66,000. Actual savings may vary depending on site-specific operating conditions and energy consumption patterns.
This project demonstrates how an integrated solar and energy storage solution can help energy-intensive businesses improve solar utilization, optimize electricity costs, and strengthen power supply reliability.
From aquaculture in Morocco to a wider range of commercial and industrial applications, ZETATECH continues to provide flexible and reliable energy storage solutions tailored to different operating requirements.
