Sola-Vent Features
Unit
The Sola-Vent is driven by a photovoltaic panel utilizing polycrystalline silicon technology which gives a high performance to size ratio and provides power even under overcast skies. Photovoltaics is a proven technology used globally for reliable solar power generation and is particularly suitable for smaller installations of the size used for the Sola-vent.
A little known fact about solar panels is that they actually work more efficiently at lower temperatures, meaning they make the most of the available energy in winter conditions.The solar panel is housed in a robust aluminium/ABS frame, which allows easy mounting to a variety of roof types using the supplied fittings, which interface discretely with the roof construction. The unit is pre-wired, requiring simple connection to the control unit and no maintenance is required.
Unit
The control unit for the Sola-vent is housed in a specially moulded, integral sealed ABS housing in the ceiling void. This unit has a controller for the solar components, which directs power from the solar panel to the fan when in use, and charges the solar batteries when the Sola-vent is not in use. A controller regulates the battery charge, preventing over and under-charging of the unit to prolong battery life and function.
The ABS unit houses two fully sealed solar
batteries, which run at 12V. These batteries are designed to allow operation for up to 7 days without any charge from the solar panel.
The special low noise fan is mounted below the roof flashing, minimising fan noise and is IP55 rated. The high-efficiency DC motor has a very long life of 50000 hours, which is in excess of 55 years under normal usage of 21/2 hours per day.
A separate timer control is connected to the PIR unit to provide fully automatic operation of the extract fan. The timer control is configured to provide an overrun of 15 minutes as required by building regulations but is adjustable.
All fittings within the ABS unit are pre-wired and installed with connectors to facilitate easy wiring to external components, simplifying installation.
Unit
The Sola-vent uses very little power from either the solar panel or the battery and the fan runs on sealed ball bearing assembly making an ultra low noise unit. The two designs available offer attractive and low maintenance systems to grace any bathroom décor.
The PIR Control
The integral miniature PIR motion sensor automatically triggers the ventilation extract when PIR detects movement in the bathroom.
This design ensures the correct level of ventilation is maintained without occupant input. The PIR is just 26mm diameter with a clear plastic housing.
SunPipe
The essential complement to the solar powered extract fan is the SunPipe, which provides soft, diffused, soothing, natural light to provide a true energy-free integrated system. The Solavent utilises Monodra
ught’s Super Silver SunPipe, which is a high purity, silver coated aluminium. The specular aluminium surface carries a 10 year guarantee and is coated using PVD (Physical Vapour Deposition) and being UV stable, provides outstanding QUV durability, with no decrease in total reflectance. The special surface treatment provides excellent colour rendition of natural light.
