MacroAir Solar HVLS Fan

Oct. 22, 2009
Calling it the first and only solar-powered high-volume, low-speed (HVLS) fan, MacroAir Technologies introduces the MacroVoltaic fan.

Although solar power is often billed as the wave of the future, purchasing solar panels, which cost an average of $3.50 per watt, can be cost prohibitive, the company notes. The MacroVoltaic fan consumes about 400 watts of power, allowing customers to leverage the benefits of solar power with smaller panels and therefore smaller investment, according to MacroAir.

MacroVoltaic’s solar panels produce DC power and are rated for full sunlight. By using panels at wattages slightly higher than needed, customers can ensure the fan functions at full speed most of the time. MacroAir also covers the fan with a 20-year warranty.

The MacroVoltaic air movement system includes the HVLS fan with an attached controller. The controller converts DC power from the solar panels into usable power for the fan motor. The system also includes solar panels, standard remote control, an optional auxiliary power supply and an optional battery backup.

When used with auxiliary backup, the MacroVoltaic fan can operate when sunlight is not available, says MacroAir. Although optional battery backup requires additional investment in solar panels, the excess wattage charges the batteries and stores the energy for use at night or during cloudy weather. When used with both auxiliary and battery backup, the fan has a continuous power source, the company says.
