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
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 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.
Yes. The thermal energy buffer stores cooling during the day and releases it at night, ensuring continuous operation.
Maintenance needs are low.
The system has few moving parts and no chemical battery cells.
Routine checks are similar to standard cooling equipment.
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.
