Wind Generator Selection
While wind generator prices have dropped, the rate of drop is nowhere near that of solar panels. The contendors under consideration at the time of purchase were:
-
Primus Windpower Air X Marine 48v 1-ARXM-15-48 is rated at 400W, with a startup speed of 8 mph. The 400W peak power is generated at a specific wind speed with most conditions producing under 200W. The Air X normally sells for about $1,200.
-
Primus Windpower Air Breeze Marine 48v 1-ARBM-15-48 is a nominal 200W generator with 7 mph start up speed. The Air Breeze normally sells for about $1,200.
The Air Breeze produces slightly more power at under 23mph and twice the power over 32mph. The Air X produces a sharp power peak of over 400W at about 28mph, then drops quickly to 100W. The Air Breeze peaks at only about 250W but sustains 200W of power at higher wind speeds.
An AIR Breeze 48V Wind Generator can produce 1-1.25 amp at 48V with 12-15 knot winds or roughly 50-60 watt. Over 24 hours this could add up to 1.2 to 1.4 kWh per day. Output drops to near zero at 7 knots or under. Rotor diameter is 46".
