SolarWhiz 40W Solar Powered Roof Ventilator With Night Kit & Adjustable Thermo/Hygrostat
Original price was: $1,414.00.$1,314.00Current price is: $1,314.00.
The 40W 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 the system doesn’t wait for solar power to run out; instead, mains electricity kicks in right away to help when solar alone isn’t enough, ensuring a constant current flow. 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.

The SolarWhiz 40w Solar Powered Roof Ventilator provides comprehensive control over your roof space environment with its adjustable Thermo/Hygrostat. This integrated feature allows you to precisely set desired temperature and humidity levels, enabling proactive heat management during hot periods and the option to retain warmth in winter. This level of customisation ensures optimal conditions within your roof.
Ensuring consistent ventilation around the clock, the SolarWhiz 40w utilises a smart power system. During daylight hours, mains electricity intelligently supplements solar power to guarantee continuous airflow, operating as a constant-current system rather than waiting for solar depletion. This efficient combination effectively removes heat and moisture from your roof space, even under varying sunlight conditions.
As night falls, the SolarWhiz 40w seamlessly transitions to operate solely on mains electricity, providing uninterrupted ventilation. This continuous operation prevents the buildup of condensation and maintains a healthy environment within your roof space. This consistent airflow, independent of sunlight, offers reliable protection against moisture damage and helps regulate temperature fluctuations, potentially improving comfort in your living areas below.
How Does It Work
For Solar Whiz to provide maximum performance, replacement air must be accessible and professional installation is required. By taking advantage of Solar Whiz, 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.
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.
