HOW SOLARWALL WORKS
01 · Absorb sunlight 02 · Draw in outside air 03 · Preheat the air 04 · Supply the building
Solar energy preheats the air your facility needs.
SolarWall uses a sun-facing perforated metal collector to warm outside air before it enters the ventilation system. This reduces the heat that conventional equipment needs to supply.
Ventilation fans pull fresh air through the small openings.
Air picks up heat as it passes through the collector and cavity.
Preheated air enters the ventilation or process air system.
Industrial decarbonisation
Decarbonising industrial heating.
SolarWall uses sunlight to preheat incoming air for industrial ventilation and processes, helping facilities reduce conventional heating demand, operating emissions and costs.
Renewable thermal energyLower fuel demandCleaner operations
Scope 1
Lower direct heating emissions
When solar-preheated air displaces on-site gas or other fuel combustion, direct emissions from industrial heating can fall.
Scope 2
Lower purchased energy demand
Where SolarWall reduces purchased electricity, steam or heat consumption, associated indirect emissions may also decrease.

From feasibility to investment
Plan your solar heating investment.
We assess local climate and solar exposure, suitable south-facing façades or roof areas, and your facility’s annual production and heating demand before modelling expected useful heat, savings and investment options.
Climate & collector fit
Location-specific weather and irradiation, shading, south-facing façade or roof suitability.
Annual heat & production profile
Heating hours, airflow and seasonal demand aligned with the facility’s production schedule.
Feasibility & investment
Modelled solar heat, fuel savings, CO₂e reductions, payback and potential funding options.
01 / ABOUT THE TECHNOLOGY
Turn your building envelope into a source of heat.
SolarWall® uses sunlight to warm outdoor air before it enters a factory's ventilation system or industrial process. The result is useful renewable thermal energy that can reduce the amount of conventional fuel required.
Installed on suitable façades or rooftops, the technology is engineered to work with your air handling equipment, airflow demand and operating profile.

ILLUSTRATIVE OUTPUT

Estimated annual collector heat potential (MWh/year)
- Potential per m² of collector
- —
- Calculation status
- Illustrative assumptions
Preliminary illustration only. The solar irradiation inputs and performance factors have not been independently validated for this website. This is not a prediction of heat available to your processes, a performance guarantee or an engineering quotation.
Methodology and assumptions
Illustrative model: annual collector heat potential (MWh) = collector area (m²) × provisional annual irradiation (kWh/m²) × 0.80 assumed orientation adjustment × 0.40 assumed collection factor ÷ 1,000. These two factors are placeholders, not measured SolarWall system performance. The irradiation input is not established as a vertical-façade, orientation-specific PVGIS series.
Provisional location inputs (kWh/m²/year): Barcelona 1,650; Madrid 1,800; London 1,000; Berlin 1,150; Paris 1,200; Rome 1,600; Istanbul 1,400. Results do not account for shading, system type, hourly weather, collector airflow, operating times, building load, or usable delivered heat. Before a project estimate, use orientation-specific PVGIS irradiation data and manufacturer-validated performance modelling.
