Top Five Micro Wind Turbines

They have been around for centuries, but they are quickly becoming the darlings of the eco-friendlies and clean energy nuts. Windmills, or in this case, wind energy generators, come in all shapes and sizes.

4. Southwest Windpower Whisper 500

small wind turbine, whisper, whisper 500The Whisper 500 can produce enough energy to power a small to moderately sized home. Formerly the Whisper 175, the Whisper 500 was completely redesigned in 2004 to work in harsh, high wind environments.

The Whisper 500 is a two bladed fiberglass reinforced blade and incorporates a patented “angle governor,” designed for quiet operations in high winds. Side-furling overspeed protection turns alternator and blades out of high winds without cutting power output.

Cost: $7,095

 

Rated Capacity: 3kw

Startup Windpeed: 7.5mph

Rotor: 15 feet (4.6 m)

Interconnection: Utility connected or battery charging

Voltage Output: 24, 32, 48 VDC or 240 VAC

Estimated Energy Production: 500 KWh/month @12.5mph

5. Bergey Excel

The Excel is a ruggedly built turbine that comes with a 5 year warranty. Connected to the grid, the BWC EXCEL can provide most of the electricity for an average total electric home at moderate wind sites. The all new GridTek 10 power processor (inverter) is the most advanced in the industry and it carries a full UL certification to the latest utility standards.

In a location with moderate winds, the Excel 10kw can provide enough electricity for the average home.

Cost: $21,900-$27,900

 

Rated Capacity: 10kw

Startup Windspeed: 7.5 mph

Rotor: 22 feet (6.7 m)

Interconnection: Utility connected or battery charging

Voltage Output: 48 VDC or 120, 240 VAC

Estimated Energy Production: 1500 KWh/month @12.5mph

*Note: Prices listed are the manufacturer’s suggested retail price, it is quite possible to find them for less (nobody pays retail anymore, right?)
