The 28W SolarWhiz Solar Powered Roof Ventilator comes accompanied by both the Adjustable Thermo/Hygrostat and the Night kit. The N-OPS kit (Also known as the Constant Current Module) is especially handy since it allows users to run the Solar Whiz installation during low-light hours, both on heavily overcast days or at night. This means that the Solar Whiz can run on mains electricity once the solar charge has depleted. It also comes with the Adjustable Thermo/Hygrostat, which is another great component that lets you adjust the required temperature for the unit to begin operating at. When these two components are combined, users get a really comprehensive roof ventilation solution.

SolarWhiz 28W runs whenever there is active sunlight reaching the solar panel, it does not include a battery to continue operation beyond daylight. For the majority of installations dealing with heat within roof space, this is suitable as direct sunlight is often the cause of excessive roof space heat. Solar Whiz is an effective solution for hot roof spaces or home interiors; providing an efficient exchange of hot air from within the property. High volumes of hot air can be extracted from the roof space and/or home interior, thus allowing for a much cooler atmosphere in the ceiling and living spaces.

The included adjustable thermo/hygrostat provides complete control over when your Solar Whiz operates. During periods of exceptional heat, this can enable the unit to operate earlier, preventing heat build-up. Alternatively, you can deactivate the system to retain heat in winter. The Night Kit can still work during more gloomy days or even throughout the night and enables your Solar Whiz to run on mains electricity once the solar charge has depleted.

How Does It Work

Optimum performance from Solar Whiz requires accessibility to replacement air and professional installation. With Solar Whiz, it is possible to extract significant amounts of hot air from the roof space and/or interior of the home. This brings about a cooler atmosphere in both living spaces and the ceiling.



Powerful Extraction

Harness the power of the sun to keep cool during summer with the Solar Whiz. During the hot summer months, 25-35% of the heat in your home is generated from your roof space. The Solar Whiz uses solar energy to start operating when the sun rises and helps to keep your roof temperature close to the outside ambient air all day.

Moisture and Condensation Control

It is important for any home to have adequate airflow in order to avoid moisture build-ups which can lead to condensation and the subsequent development of mould or mildew. Therefore, it is essential to take measures that ensure proper ventilation within the home to reduce the risk of such issues.

All data is provided the manufacturer. Capacity figures are based on the extraction rate of the unit in 'freeflow'. This means without any ducting, vents or other components. As you add ducting to a fan it will impact the extraction rate as this introduces resistance. For this reason if you are ducting an extraction fan it is best to keen the run as short, tight and direct as possible. For more information please view our exhaust fan buying guide.

For comprehensive warranty information relating to this product please visit the manufacturers website.

The incredibly flexible and adaptable Solar Whiz system can be seamlessly integrated into almost any tile or metal roof, and our extensive selection of accessories will ensure that even the most complex installation requirements can be met with ease.
The ducting system is a great solution for effective temperature control and to prevent condensation. It draws air directly from rooms using a ducting system and can be installed on its own or in conjunction with other roof space extraction setups.
  • Powerful ventilation for entire rooms.
  • High performance air and condensation extraction.
Solar Whiz stands out from other suppliers due to its holistic approach to efficiency. By extracting hot air from your roof space and replacing it with cooler air through eaves or ceiling vents, enhances the unit’s performance.
  • Decrease the thermal load of your roof space.
  • Ducted air conditioners can operate with improved effectiveness.
This method is especially effective in multistory houses and can be used alongside evaporative cooling to get rid of excess humidity. By extracting air from the rooms, you can significantly reduce the temperature and create a more comfortable living environment.
  • Improve the efficiency of your evaporative air-con system through increased air circulation.
  • Fresh air is circulated through your living spaces.
