Dec to Jan Results -Retraction - I made a mistake last month

Results report for Dec 27 to Jan 27


I was putting in my calculations for this month and I found in a mistake in my spreadsheet. In my excel formula, I copied downward the wrong calculations for the last 2 months. I found this because the numbers just weren’t adding up. We had an average wind speed this month of 8mph but the results didn’t improve on my sheet. So I’ve gone back and fixed my error.

The wind gusts (show as blue dots) did cause the system to shut down several times this month.

Month of Jan Wind Speed

 This month (Dec 27 to Jan 27) average 8 mph with a gain of 367KWH with the inverters putting out 581KWH.




Month of Dec Wind Speed


Last month the average wind speed was 6 mph and we made 320KWH with the inverters putting out 408 KWHs

  
We had some high peaks of wind speed, but these wind gusts cause the system to shut down in protection mode . Also,  the system needs to do a lot of yawing to move out of the wind on these gusty days. A slower steady wind speed will produce much better results.
