Cold Storage Powered by the Sun. Guaranteed Stable Temperature, 24/7.
Cold storage facilities are among the most energy-intensive industrial assets, operating 24/7 with strict temperature stability requirements. Sun Ice Energy transforms conventional refrigeration into a solar-powered thermal energy storage system using patented PCM (Phase Change Material) thermal energy buffers. The result: lower operating costs, reduced grid dependency, and guaranteed temperature stability.
CORE VALUE
Protect your inventory and your bottom line. Sun Ice transforms cold storage into a clean, cost-controlled asset powered primarily by solar energy. Operating costs and carbon footprint are significantly reduced, with the electrical grid acting only as a silent backup for ultimate peace of mind.
Why Solar Thermal Storage for Cold Chain?
Refrigeration can represent more than 50% of total facility energy consumption in cold chain logistics. By storing renewable energy as cold through controlled PCM freeze–melt cycles, facilities gain energy resilience, peak load reduction, and long-term cost stability.
- Reduce peak demand charges through thermal load shifting
- Stabilize operating costs against volatile electricity pricing
- Enhance refrigeration resilience during grid instability
- Support ESG, sustainability, and net-zero carbon goals
Near Zero Energy with Temperature stability (±0.5 °C).
HOW DOES IT WORK
Generate & Cool
Your on-site solar panels serve as the primary power source. This renewable electricity simultaneously: Powers the chillers to handle real-time cooling demand (countering infiltration heat, equipment loads, door openings, etc.) and Charges the Ice Wall thermal storage buffers by freezing the Ice walls, building a reserve of stored cooling capacity
Discharge On Demand
When solar power is unavailable—at night, during cloudy periods, or peak tariff windows—the Ice Wall seamlessly releases stored cooling energy to maintain precise temperature stability, minimizing or eliminating the need for grid electricity.

F.A.Q
Sun‑Ice is designed so that solar is the primary source of power for cooling.
- Off‑grid containers: 100% solar‑powered with no grid connection. Solar also recharge auxiliary batteries for LED lighting and ventilation.
- Large buildings: Solar provides most of the cooling energy, with the grid acting as a backup during extended low‑sun periods. Surplus solar electricity can be exported back to the grid. Making the building energy positive.
Sun‑Ice stores thermal energy, not electricity.
This makes it:
- More efficient for cooling applications
- Longer‑lasting (batteries have a limited life cycle for daily storage)
- Lower‑maintenance
- Safer (no lithium, no “run away” risk)
- More cost‑effective for large cooling loads
The Sun‑Ice thermal energy buffers have a 50‑year lifespan.
Other third‑party components follow the manufacturer’s warranty.
Sun‑Ice is designed for new buildings with strong insulation and high‑performance envelopes.
The better the insulation, the lower the cooling load — and the more efficiently Sun‑Ice units operates.
We work closely with architects to optimise:
- Building orientation
- Insulation levels
- Shading and solar control
- Ventilation strategy
- Thermal mass and envelope performance
This integrated design approach ensures the building requires as little cooling as possible.
Maintenance needs are low.
The system has few moving parts and no chemical battery cells.
Routine checks are similar to standard cooling equipment.
