Cold Storage Solar: Powering Refrigerated Warehouses
Cold storage facilities are among the most energy-intensive commercial buildings. Solar can dramatically reduce the electricity costs of constant refrigeration.

Cold Storage Energy Profile
Refrigerated warehouses run cooling systems continuously, creating substantial electricity bills. Solar generation during daytime hours coincides with peak cooling demands, especially in summer when cooling loads increase.
Energy Consumption Benchmarks
| Temperature Range | kWh per sqm/year | % Suitable for Solar |
|---|---|---|
| Chilled (0-5C) | 150-250 | 60-70% |
| Frozen (-18 to -25C) | 300-500 | 50-60% |
| Deep Freeze (-30C) | 500-800 | 40-50% |
Solar Advantages for Cold Storage
- Large roof areas: Single-storey warehouses offer extensive roof space
- High daytime demand: Cooling peaks align with solar generation
- Flat roofs: Easy installation with optimal panel positioning
- Battery potential: Store excess for overnight cooling
Case Example
10,000 sqm frozen food warehouse:
- Annual consumption: 4,000,000 kWh
- 500kW solar system installed
- Generation: 475,000 kWh/year
- Self-consumption: 90%+
- Annual savings: £120,000+
- Payback: 3.5 years
