The challenge

Rising electricity costs and an unreliable grid supply endangered chilled goods and customer service at Grocery Express, a busy supermarket in George. The business required a cost-effective, resilient energy solution to protect critical commercial refrigeration systems and ensure uninterrupted service continuity during load shedding.

The SSS solution

Specialized Solar Systems engineered and installed an 85.8 kVA hybrid solar energy solution featuring a total PV array capacity of 95.6 kWp (comprising an 85.8 kWp grid-tied array and a 9.8 kWp dedicated backup array) paired with 64 kWh of LiFePO4 battery storage. The system delivers seamless switchover functionality across solar, battery, and grid supply.

Results and benefits

The system guarantees continuous power delivery for essential refrigeration systems and checkout point-of-sale operations. By providing reliable energy delivery, the project significantly reduces operational downtime and inventory spoilage while achieving an estimated payback period typically under 6 years.
