Solar-Powered Air Extraction

A solar roof ventilation fan uses energy from its solar panel to power a motor that extracts air from the roof space. Replacement air enters through suitable inlet openings.

This creates airflow through the roof cavity rather than simply circulating the same air inside it.

Why Inlet Ventilation Matters

An exhaust fan needs a path for replacement air. Suitable eave or other purpose-designed inlet vents help air move through the roof space.

Roof design, existing vents, insulation and obstructions affect the airflow path. Follow the installation guidance for your roof and fan model.

What Affects Performance?

Sunlight, outdoor temperature, roof construction, inlet ventilation and fan positioning all influence results. Ventilation is not refrigeration, and temperature reductions or electricity savings cannot be guaranteed.
