Efficiency

Guarantee

The Sola-vent system is guaranteed for 10 years. This includes the Solar Cell, extract fan, solar controller, solar batteries, miniature PIR and overrun timer. All SunPipe components are guaranteed for 10 years.

Winter Operation

The Sola-Vent has been designed for UK weather. Careful selection and sizing of the Sola-Vent is designed is designed to provide the required level of ventilation to meet building regulations. Just 2 hours of sunlight per day will provide energy free operation. The built in batteries themselves will provide 7 days backup operation.

Acoustic Performance

The Sola-Vent system is designed to be an ultra low noise system. The low powered fan is mounted within a ball bearing assembly, which in turn is fitted to two anti-vibration gaskets and the arrangement is fitted within an ABS unit above ceiling level.

U-Value

Currently, testing is being carried out to determine the U-Values for the Sola-Vent system. However, other work carried out on light pipes has produced a result of 0.315W/K.

Mains Powered Sola-Vent

With the advantages of low noise and automatic operation, a mains powered version of the Sola-vent is also available. All required power is taken from the lighting circuit, minimising installation complexity and time. A DC transformer takes the place of the solar components and provides power to the fan unit. The mains Sola-vent may be specified on occasions where roof installation of a solar panel is not possible for any reason.
