Services
SolarWall Single-Stage
This system preheats ventilation air using solar energy for commercial buildings. It reduces heating costs by up to 50% while maintaining indoor air quality. Ideal for facilities with high ventilation demands like schools and industrial plants.
SolarWall Two-Stage
A dual-layer system achieving higher temperature rises for industrial applications. Provides up to 75C temperature increase above ambient air. Suitable for manufacturing facilities requiring process heat and space heating.
SolarDuct Rooftop Heating
Engineered for roof-mounted installations where wall mounting isn't feasible. Delivers solar-heated air directly into building ventilation systems. Reduces reliance on fossil fuels for HVAC in warehouses and large facilities.
PV/T Systems
Combines photovoltaic electricity generation with solar thermal heating. Simultaneously produces power and heated ventilation air. Maximizes roof space utilization for buildings targeting net-zero energy consumption.
NightSolar
Reverses solar wall technology to cool buildings at night. Draws heat from indoor air using nocturnal radiation. Reduces mechanical cooling costs in commercial buildings without additional energy input.
