Portable, Renewable-Powered Containers for Offices, Clinics, and Accommodation
Sun Ice Energy delivers fully climate-controlled, off-grid modular containers powered 100% by solar energy. Designed for remote industrial sites, emergency deployments, and autonomous infrastructure, our off-grid containers integrate photovoltaic generation with patented PCM (Phase Change Material) thermal energy buffers to provide reliable cooling, humidity control, and indoor comfort — without diesel generators, fuel logistics, toxic fumes, noise, or CO₂ emissions.
CORE VALUE
Sun Ice transforms portable infrastructure into a clean, cost-controlled, energy-independent solution. These solar-powered containers provide stable internal conditions anywhere — from oil & gas sites and mining camps to disaster relief zones — with zero diesel, zero noise, and zero direct carbon emissions.
Why Off-Grid Solar Thermal Storage?
Traditional off-grid cooling relies on diesel generators or lithium battery systems, both of which introduce high operational costs, maintenance complexity, and lifecycle degradation. By storing solar energy as cold through PCM freeze–melt cycles, Sun Ice Energy enables long-duration thermal autonomy with dramatically lower lifecycle costs.
- Eliminate diesel fuel logistics and associated emissions
- Reduce operating expenses (OPEX) with solar-powered climate control
- Ensure continuous indoor comfort in inexistant or unstable grid locations
- Enhance sustainability performance for ESG and environmental compliance
<3 years ROI, $0 OPEX, 50‑year lifespan
HOW DOES IT WORK
Generate & Store
Solar panels installed on or adjacent to the container drive high-efficiency HVAC systems while simultaneously charging Sun Ice PCM thermal energy buffers built directly into the container walls (and conventional batteries for LED lighting and low energy ventilation).
Discharge On Demand
Stored cooling capacity is released automatically to maintain stable internal conditions — typically 24°C and approximately 50–60% relative humidity — even when solar production is unavailable.
Continuous Comfort
Predictive climate control technology regulates temperature, humidity, and CO₂ levels to ensure safe, quiet, and comfortable environments 24/7.
Daytime Heating
Solar energy can also provide heating during daylight hours where required (Optional), although the system is primarily optimized for cooling and humidity control.

F.A.Q
The system is engineered with enough storage capacity to handle most cloudy periods.
For large buildings, the grid can supplement the system if needed.
Sun‑Ice is integrated during the building’s design and construction phase.
We work with architects, engineers, and contractors to ensure the system is sized correctly and installed as part of the building’s cooling infrastructure.
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
Yes — but only during a major renovation where the building is taken back to its structural frame with state of the art insulation and ventilation.
Sun‑Ice is primarily designed for new construction, where it can be fully integrated into the building from the start.
Sun‑Ice uses solar energy to freeze a thermal energy storage buffer during the day.
That stored cooling is then released to keep the building comfortable at night or during cloudy periods.
No electrical batteries are required when used with Grid support.
