Did you ever try removing a few blades?

I did take 5 of the 10 blades off, but the start up was much worse (higher mph winds), the overall power for a given wind speed was lower. I understand the logic from a previous post the suggestion of removing blades to help with top end power, but at the moment, from the 40 mph winds I have seen, it just keeps making more watts. I think that with this design, and also my total power requirement, the extra blades will help to add a self regulating feature, as when the wind speed is high enough to make too much power, the previous blade will steal the available from the next and stop an over speed situation occurring. I only need to make an average of 200 watts an hour, whether through wind or solar, to run the LED lights, wood burner circulator pump (hot water and domestic heating), telecoms and computers.

What is the cost of the wind turbine ? The design goal is 800 wats ?
Thanks , Wyr God bless |

The power output is 800 watts at 28mph and over a kw at 35mph. Theoretical safe continuous maximum power output on my turbine is 1.8kw, as it has a 30 amp fuse and is charging a 48 volt system, with a maximum system voltage of 60 volts. 1.8kw should happen about 50mph, but we haven't had any winter winds to try the theory yet.
It cost me £545, but I went to the supplier to collect and pay CASH. |

How much do you pay per kwh ? I am guessing , in the UK , heating cost is more significant than air conditioning cost ? BTW , I have been watching the British series " Wheeler Dealers " & enjoy it . :-) God bless Wyr |

Electricity is 12 pence a kw. Heating accounts for 44% of all energy bills but thats due to poorer insulation in the average UK home. At the moment it is 32 celsius here (which is scorching!), winter dropped to minus 10C. When you consider that Sweden only has a 27% heating cost, but a much colder environment, it shows how far behind the UK is... the average energy bill is now over 10% of a household income, and set to rise sharply when the coal fired power stations get closed forever in 2015. In dollars, your looking at $1000 for one of these, but then you can get a twin core pma from missouri or south west windpower? for less, as you dont have to pay import duty.

Great little wind turbine

I bought them at Wind turbine power generator and solar energy grid ties and they sell for real cheap like $299.00 Great investment! |
