Renewable-Powered Cooling for Mission-Critical Server Rooms
Server rooms and edge data environments require continuous, stable cooling to protect uptime, data integrity, and hardware lifespan. Sun Ice Energy delivers a solar-powered thermal energy storage solution using patented PCM (Phase Change Material) Ice Wall technology to ensure 24/7 temperature stability with minimal grid dependency. The result: resilient, cost-controlled, and low-carbon IT cooling.
CORE VALUE
Keep your servers cool, stable, and secure — without relying entirely on the grid. Sun Ice delivers a clean, cost-efficient cooling solution that protects uptime and significantly reduces operational energy costs. Our intelligent Ice Wall thermal battery ensures your server room remains at optimal temperature around the clock, powered primarily by solar energy, with the grid serving only as backup.
Why Renewable Cooling for Server Rooms?
Cooling can represent 30–50% of total IT facility energy consumption. Traditional systems operate in real time and are fully exposed to peak electricity tariffs and grid instability. By integrating solar PV with PCM-based thermal energy storage, facilities gain energy resilience, peak load reduction, and predictable cooling costs.
- Reduce peak demand charges through thermal load shifting
- Improve energy efficiency and optimize cooling performance
- Enhance uptime resilience during grid instability
- Support ESG reporting and low-carbon IT infrastructure goals
Uptime protection – Reduced OPEX – Zero CO₂ emissions
HOW IT WORK
Generate & Cool
On-site solar panels drive high-efficiency chillers to meet real-time cooling demand while simultaneously charging the Ice Wall thermal battery.
Discharge On Demand
When solar power is unavailable—at night, during cloudy conditions, or peak tariff periods—the Ice Wall seamlessly releases stored cooling capacity to maintain stable server room temperatures.
Continuous Protection
Even during grid outages or demand spikes, stored thermal energy ensures uninterrupted cooling, minimizing the risk of downtime, overheating, or equipment failure.

F.A.Q
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
Sun‑Ice works best in hot, sunny climates where cooling demand is high.
It performs well in tropical, subtropical, and desert regions.
It depends on the building size, insulation quality, and cooling load.
During design, we work with the architect to size the solar array and thermal energy storage buffer so that solar provides the primary cooling energy year‑round.
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.
Sun‑Ice is a solar‑powered thermal storage system that provides reliable, off‑grid or solar‑primary cooling for new buildings. It stores energy from the sun as cooling power and delivers it 24/7.
Protects uptime for small businesses and offices.
