Why Nordic Sunwall

Free solar heat. Even at -40°C.

83% efficiency · 40°C temperature rise · 6-month payback

A simple black aluminium sheet manufactured in the Netherlands. A small fan. Free hot air from the sun.

No solar panels · No batteries · No inverters · No electricity generation · Just free hot air

It does not need warm air — it needs sunlight. As long as the sun shines, it works.

Who It Is For

• Farms: Pigs, poultry, calves, reindeer, musk oxen — 40–50% gas saving
• Public buildings: Schools, churches, community centres, care homes
• Commercial: Bars, restaurants, warehouses, workshops
• Balconies & homes: DIY kits for apartments and houses
• Extreme cold: Antarctic research stations — works at -40°C and colder

The colder it is, the better it works.

The Numbers (Sweden)

One panel (2 m²):

• Free heat: 600–900 kWh per year
• Annual saving: €120–180
• Installed cost: €500–800
• Payback: 6–9 months

A typical farm (20 panels / 40 m²):

• Free heat: 12,000–18,000 kWh per year
• Annual saving: €2,400–3,600
• Payback: 6–12 months

For different applications:

• Pig farms and poultry houses: 40–50% gas saving · 6–9 months payback
• Calf stables: 25–35% gas saving · 9–12 months payback
• Reindeer and musk oxen farms: 25–40% gas saving · 9–15 months payback
• Schools, churches, community centres: 20–35% gas saving · 12–18 months payback

Why the Nordics Are Perfect

Clear winter skies · Bright sun · Cold air · High energy prices

On a clear winter day in Sweden, solar radiation hits 1,200–1,500 W/m². The system works best when it is coldest. The bigger the temperature difference, the more heat you capture.

The heating season is 7–8 months — more months of free heat, faster payback.

If it works in Antarctica, it works anywhere in the Nordics.
