Solar Hot Water for Extreme Cold & Remote Sites

Designed for the harshest environments on Earth.

The Aurora Skid is not just for hotels. With our cold‑climate modification package, the same containerised solar hot water plant can operate reliably in:

• Polar research stations (Antarctica, Arctic, Greenland)
• Mining camps (Canada, Alaska, Siberia, Scandinavia)
• Oil & gas sites (North Slope, Northern Russia, offshore)
• Logging and forestry camps (remote, off‑grid, extreme winters)
• Communities in cold climates (apartment buildings, villages, housing cooperatives in northern regions)

Why these customers choose Aurora Skid

• No roof work — container sits on gravel, ice, or a simple pad
• Cuts diesel use — solar reduces fuel consumption by 50‑80%, less fuel to fly or truck in
• Rugged and self‑contained — everything inside a standard shipping container
• Cold‑climate ready — modified for temperatures down to -40°C and lower
• Low maintenance — no complex tracking, just evacuated tubes and a simple glycol or drain‑back system

What makes the "Extreme Cold" version different

Our standard system works down to -20°C with propylene glycol. For polar and sub‑arctic conditions, we offer a cold‑climate upgrade package:

• Drain‑back system — no freeze risk at any temperature (water drains into a heated tank inside the container when the pump stops)
• Heat tracing — electric heating cables on all external pipes
• Extra insulation — container walls, roof, and pipes
• Internal container heater — small electric or diesel heater keeps equipment above freezing
• Wind‑rated collector frame — reinforced for high winds and snow loads

Solar thermal has been proven in Antarctica since 2009. Read our Proven Technology page for details.

Modular and scalable

The Aurora Skid is fully modular. Need more hot water? Add a second container. Or a third. Or connect multiple containers in parallel. For large research stations or mining camps with 500+ people, we can supply as many containers as you need. Start small. Scale as your site grows.

The same applies to cold‑climate communities — a village of 50 houses can start with one 20ft container and add more as the community expands.

Sizing for remote sites and cold communities

Small camp or community (10‑20 people):

• Daily hot water (60°C): 500‑1,000 litres
• Collectors: 6‑10 (20‑tube)
• Tank: 1000 litres
• Container: 20ft

Medium camp or community (30‑50 people):

• Daily hot water: 1,500‑2,500 litres
• Collectors: 15‑20
• Tank: 2000 litres
• Container: 20ft

Large camp or community (60‑100 people):

• Daily hot water: 3,000‑5,000 litres
• Collectors: 30‑40
• Tank: 3000‑5000 litres
• Container: 40ft

Research station or large community (100‑200 people):

• Daily hot water: 5,000‑10,000 litres
• Collectors: 50‑80
• Tank: two 3000 litre tanks or larger
• Container: multiple 20ft or 40ft

Savings example — remote mining camp (Northern Canada)

Assumptions:

• 50 workers, 2,500 litres per day hot water
• Diesel heating: €1.20 per litre, 10 kWh per litre (boiler efficiency 80% → 8 kWh useful per litre)
• Daily diesel for hot water: approximately 150 litres per day → €180 per day
• Solar provides 60% in winter (low sun), 80% in summer

Annual diesel saving: approximately 30,000 litres → €36,000
System cost (installed, cold‑climate package): approximately €35,000
Payback: about 1 year

In polar regions with 24‑hour summer sun, payback can be even faster.

Savings example — cold‑climate community (Northern Finland)

Assumptions:

• 40 apartments, 100 residents, 5,500 litres per day hot water
• Electric heating (resistive): €0.20 per kWh
• Solar provides 50% of annual hot water (due to shorter winter days)

Annual saving: approximately €8,000
System cost (installed, cold‑climate package, 40ft container): approximately €40,000
Payback: 5 years

With government grants for northern communities, payback can drop to 3 years.

FAQ — Extreme Cold Version

Q: Will the evacuated tubes freeze or break in -40°C?
A: No. The vacuum inside the tubes is an excellent insulator. The heat pipes are filled with a freeze‑tolerant fluid. With our drain‑back system, there is no water in the collectors or external pipes when the system is off — so nothing can freeze.

Q: What happens when there is no sun for weeks (polar night)?
A: The system relies entirely on backup heating (diesel boiler, electric heater, or waste heat). The container and tank are heavily insulated, so heat loss is minimal. You simply run your existing heater during dark periods.

Q: Can the system be airlifted or sled‑towed?
A: Yes. The 20ft container is designed for helicopter sling loads (with certified lifting points) and can be towed on a sled. Ask us for the polar logistics package.

Q: Do you offer remote monitoring?
A: Yes — our IoT kit works via satellite (Iridium, Starlink) or HF radio. You can monitor tank temperature, pump status, and freeze protection from anywhere.

Q: How much does the cold‑climate upgrade cost?
A: Approximately €3,000‑5,000 extra per container, depending on the level of insulation, heat tracing, and drain‑back complexity. Contact us for a site‑specific quote.

Q: Can this system work for a village or apartment building in northern Norway?
A: Absolutely. The cold‑climate package is ideal for any community in regions with harsh winters. You get the same benefits — no roof work, shared savings, and reliable hot water even at -30°C.
