The world's first: 24/7 Free Solar Heat in a 40ft Container

Imagine a mobile heating system you can place anywhere, that uses zero diesel or gas, and delivers heat day and night. That is the Transpired Solar Container. By combining our high-efficiency modular perforated solar collector with a massive thermal gravel battery, we have developed the world's first fully off-grid, mobile solar heating unit.

No diesel. No noise. No emissions. Just free heat, 24 hours a day.

Why a Container instead of a fixed wall?

Traditional solar collectors are permanently mounted to a building. Our container offers three enormous advantages:

• Fully Mobile: Relocate the container when you finish a project, move premises, or need to temporarily heat a construction site or event.
• Plug-and-Play: The unit is built perfectly airtight in our factory. You drop it down, connect a duct to your building, and it works.
• Rent or Buy: Test the technology risk-free with a rental contract, or purchase the container permanently.

How does 24/7 heating work?

The secret lies in the intelligent bypass and the thermal battery:

• Daytime (Charging + Heating): The sun heats the 30 m² solar collector. A fan blows the hot air directly into your building. At the same time, excess heat is stored in an insulated 10 m³ gravel battery.
• Nighttime (Discharging): The sun is gone, but the gravel battery is hot. The fan draws cold air through the gravel, heats it up to 30-40°C, and blows it into your building.
• The 50/50 Control: You decide exactly how much heat goes directly inside and how much is stored for the night.

Container Specifications

• Dimensions: 40ft High Cube container (approx. 12 x 2.4 meters).
• Collector Surface: 30 m² on the south facade (0.5 mm marine-grade AlMg3 aluminium).
• Peak Power: Up to 18 kW of free heat on a sunny winter day.
• Storage Capacity: 10 m³ gravel battery (good for 100+ kWh of heat).
• Temperature Rise: 25–40°C (up to 80°C in special low-flow mode).
• Lifespan: 25+ years. Operates reliably at -40°C. No glass to break and no snow accumulation.

Who is the Container ideal for?

• Livestock Farms: Provide poultry, pig, and calf stables with continuously preheated ventilation air.
• Construction Sites & Events: Temporarily heat offices, canteen tents, or VIP areas without expensive diesel generators.
• Mining & Remote Locations: Off-grid heat for camps where there is no power grid.
• Emergency Relief: Instantly deployable as safe, fuel-free heating for disaster relief shelters.

Why choose Transpired Solar?

• Proven Technology: The foundation (unglazed transpired collectors) has been used for years by companies like DHL, FedEx, and Amazon.
• Container Experience: Our founder previously built the world's first containerized biodiesel refineries (BioKing). We know better than anyone how to build industrial systems perfectly inside a shipping container.
• No glass, no snow problems: Our vertical plates are unglazed. Snow slides off, and within an hour of sunrise, the system is working again.

Rent or Buy?

• Rent from €800 - €1,200 per month. Includes delivery, installation guidance, and maintenance. (Minimum rental period: 3 months).
• Buy from €22,000 - €28,000, depending on the desired configuration and material thickness.
