One of the most common questions homeowners ask is how many solar ventilators are required.
The answer depends on several factors, including roof size, layout, and airflow balance.
As a general reference, one solar ventilator typically covers approximately 700–800 square feet of roof area.
For many double-storey homes in Malaysia, installing one to two units is usually sufficient to achieve balanced ventilation.
The final recommendation should always consider roof structure and proper placement to ensure effective heat extraction.
