KoolVents solar attic fans help exhaust trapped hot air from your roof space, improving attic ventilation and helping reduce heat buildup above your living areas – all powered by the sun.
Under the Philippine sun, roofs can absorb significant heat throughout the day. Without adequate roof and attic ventilation, hot air can accumulate beneath the roof and contribute to uncomfortable conditions in the rooms below.
Heat buildup in the roof space can make rooms directly below the roof harder to keep comfortable, especially during hot afternoons.
Roof and ceiling materials can continue releasing accumulated heat even after outdoor temperatures begin to fall.
More heat entering your living space can make your airconditioning system work harder to maintain your desired indoor temperature.
When excess roof heat transfers into living spaces, air-conditioning systems may need to run longer to maintain comfortable conditions.
Poor roof-space ventilation can allow excessive heat and moisture to accumulate inside the attic or roof cavity
Without proper attic ventilation, hot air can remain trapped beneath the roof instead of being exhausted outdoors.
The solar panel converts sunlight into electricity to operate the ventilation fan - without drawing electricity from the grid during solar operation.
The solar attic fan draws accumulated hot air from the roof space and exhausts it outdoors.
With properly designed intake ventilation, replacement air can enter as hot air is exhausted, helping improve airflow through the roof space.
KoolVents offers solar-powered roof and wall ventilation options for different home designs, roof orientations and installation requirements.
Uses sunlight to operate the ventilation fan, with no grid electricity consumption during solar operation.
Continuously exhausts accumulated hot air from the roof space while sufficient sunlight is available.
Promotes airflow through properly ventilated roof spaces by helping exhaust hot air outdoors.
Reducing excessive roof-space heat may help limit heat transfer toward the rooms below.
Choose from roof-mounted, fixed and wall/gable ventilation solutions for different requirements.
Our team helps determine appropriate positioning and installation based on your roof requirements.
Have other questions?
A solar attic fan is a ventilation fan powered by a solar panel. It helps exhaust hot air from an attic or roof space without
consuming grid electricity during solar operation.
As the roof heats up during the day, hot air can accumulate underneath it. A solar attic fan exhausts this hot air outdoors
and helps promote airflow through a properly ventilated roof space.
A solar attic fan is designed primarily to reduce heat buildup in the attic or roof space. Its effect on indoor temperature
varies depending on roof construction, insulation, ceiling design, existing ventilation, weather and other factors.
Standard solar-powered operation depends on available solar energy, so fan performance varies with sunlight conditions.
Adjust this answer if a specific KoolVents model has verified battery or AC/DC operation.
During solar operation, the fan is powered by its solar panel and does not draw electricity from the grid.
The appropriate number depends on factors such as roof-space size, roof design, ventilation openings and the airflow
capacity of the selected KoolVents model. Contact us for a recommendation based on your property.
In many cases, yes. Installation suitability depends on the roof material, structure, location and selected KoolVents model.
Proper attic ventilation can help remove warm, humid air from the roof space, but moisture problems may also be caused by leaks, condensation, inadequate insulation or other building conditions.
Solar attic ventilation systems generally require minimal maintenance, but periodic inspection and cleaning of the solar panel and ventilation components can help maintain proper operation.
