I have a Windmax H12, 1kw, 24v, 5 blade wind turbine and want to know if a 11 blade rotor of about the same diameter will increase the turbines speed? The turbine is rated at 28mph 1kw. If I could bring the mph fill load requirement down that would help produce more power to the Outback. Thanks Doug Gassett firstname.lastname@example.org

- My RE system: 1 ea. Outback GTFX 2524 , 1 ea. 175 amp dc breaker
18 ea. Schott 230 solar panels. 4 deep cycle batteries and grid- tied to REA with 60 amp ac breaker.
There is only so much energy available in wind. That's the bad news. The good news is that A = pi x r ^ 2, so doubling the swept area doesn't require but a 40% larger rotor. That might be a better solution to light winds.

If you have light winds for an average you may want to investigate and upgrade to a larger unit with more swept area for greater power production in your average winds.
The increase in blades from 5-10 will make more drag in lower air speed and less power.
Less blades will turn faster and make more power.....such as two.........but they tend to chop the air when yawing and in turbulent winds and 3 blades have become the norm.
