89kW+180kWh Solar Battery Backup for Supermarkets in Panama

In the Caribbean, energy stability directly affects daily business operations. Frequent grid outages and high electricity costs make it difficult for supermarkets to operate efficiently. Reliable power is not just a convenience. It is essential for keeping refrigeration running, protecting inventory, and serving customers without interruption.

Namkoo is proud to announce the successful completion of its sixth supermarket solar project in the Caribbean, delivering a high-performance hybrid solar solution with a dependable solar battery backup. This system now powers a local supermarket around the clock, ensuring stable operations day and night.

Project Overview: Designed for Continuous Operation

This project was engineered to provide the best power supply for a commercial retail environment where downtime is not an option.

System Configuration

• Solar Capacity: 89kW photovoltaic system

• Energy Storage: 72kW / 180kWh lithium battery storage

• Solar Panels: 144 units of 620W N-Type TOPCon monocrystalline solar panel technology

• Inverters: 6 units of 12kW hybrid storage inverters, customized for Caribbean voltage standards

• Battery System: 14 units of 15kWh lithium solar batteries using Grade A cells with over 6,000 cycles

This hybrid solar system seamlessly integrates solar generation, battery storage, and grid power to ensure uninterrupted electricity supply.

How the Solar Battery Backup Works

During daylight hours, the monocrystalline solar panels convert abundant Panama sunlight into clean electricity. This energy is used first to power supermarket operations. Any excess energy is stored in the lithium battery system.

When evening arrives or grid power becomes unstable, the solar battery backup automatically discharges stored energy. Refrigerators, lighting systems, checkout counters, and air conditioning units continue to operate without disruption.

If the grid fails entirely, the system switches smoothly to off-grid mode. Customers inside the store notice no difference. For the owner, this means peace of mind and predictable energy costs.

Why This System Is Ideal for Supermarkets

Supermarkets demand reliable, high-quality power. Even short outages can result in spoiled food and financial losses. Namkoo designed this system to meet those challenges head-on.

Stable Power for Critical Loads

Cold storage, freezers, and lighting systems remain fully operational even during extended outages.

Reduced Energy Costs

By maximizing solar self-consumption and reducing reliance on the grid, the system significantly lowers monthly electricity bills.

Long-Term Reliability

The lithium solar batteries are built with Grade A cells and offer a cycle life exceeding 6,000 cycles, ensuring years of dependable service.

Seamless Operation

Hybrid inverters allow automatic switching between grid-connected and off-grid operation without manual intervention.

Built with High-Efficiency Components

Every component in this project was selected to deliver long-term value and performance.

The monocrystalline solar panel array uses N-Type TOPCon technology, which provides higher efficiency, better low-light performance, and slower degradation over time.

The lithium solar batteries offer high energy density, enhanced safety, and stable output even under demanding commercial loads. Combined with intelligent hybrid inverters, the system delivers a truly reliable energy solution.
