SolarWall technologies address different use cases. Selection should begin with the air system, not the product label.
← All insightsUses a micro-perforated absorber to preheat ventilation air and can function as an architectural building envelope element. Particularly relevant when façade area, a connected AHU and meaningful fresh-air demand coincide.
The incoming air exchanges heat in successive stages to obtain a larger temperature rise. It may be appropriate where thermal lift is critical, but higher temperatures must still be assessed against airflow and useful annual heat.
A modular, roof-oriented alternative for facilities where façade construction or routing is challenging. The collector heats outdoor air before it enters ducting or air handlers.
Photovoltaic modules generate electricity while a coupled thermal air path captures useful heat. Electricity and heat must be modelled as separate outputs; their combined system results depend on detailed design.
NightSolar uses the night-sky radiative cooling phenomenon, rather than daytime solar heating. It is a distinct application with different weather and operating prerequisites.
Assess net useful heat, temperature lift, airflow, pressure drop, controls, ducts, available solar area and O&M together. Do not infer product performance from a single benchmark alone.
