The MacroVoltaic fan from MacroAir Technologies is a solar-powered high-volume low-speed (HVLS) industrial fan. HVLS fans generate a column of air that flows down to the ground and outward 360 degrees, allowing air to mix and circulate more efficiently and generate less noise and dust than other industrial fans, according to the company. Because MacroAir fans use only 400W of power, they are suitable for smaller, less-expensive solar panels. MacroVoltaics panels have a 20-year warranty, and are rated for full sunlight. The system also includes a standard remote control, an optional auxiliary power supply, and an optional battery backup. macro-air.com
