Happy Anniversary!

Wed July 27th was our one year anniversary of being connected to the grid.





First – This month’s reading.  July is not a good month for wind we made  76KWH



Here is a graph I put together on wind speed vs.power produced. 
















This graph shows the average wind speed for the day and the power made for the day.


The reading from the inverter measuremt which shows the power they made before the loss of the system was 181.7 KWH.


For the year the inverters made 1,719KWH. Maybe not so bad considering the system was down most of the time between Sept and June.


My monthly reading added to gether  is a net of 599 kWH for the year

We’ve been graphing each day – power gained on windy days and power lost on calm days is about 2 to 3 KWHs.  When the wind is ~2.5m/s it seems to break even. The system seems to use about 300watts without any wind.

  1. 599 kwh x 10 cents a KWH = $59.90 of power production for the year.

    The ReDriven Wind Turbine costs about $60,00 to install (before rebates)

    Total return on investment = .00099% or not even 1/100% return.

    Patback period (excluding any interest on $60,000) 1001 years!

    Pretty abysmal if you ask me.

  2. Your right - It hardly worked during the months when I could produce some power. I hope this next year to have a figure represents what it can do when there is more up time than down time.
