The Outhouse Powerwall
#31
Progress continues. September has been a wet month, more so than August! But even with all that rain I managed to finally get the panels off the lawn and on a rack.


Gah! All that ground water!


Mounted!



September's output has been abysmal! I can't stand the constant dreary weather, nothing but overcast clouds and rain. I don't think I can hack it in the Pacific northwest!

 


Couple more interesting math:


Code:
                                                Estimated    Estimated
           Total PV kwh     Total AC Output    Idle Loss    90% Efficiency Loss

August         184.8kwh         132.7kwh          36kwh        14.8kwh

September      122.2kwh          74.9kwh          36kwh        8.6kwh

There was barely a few days of full sun the entire month. I couldn't believe how much cloudy days affected my output. There was only a few days when I reached full state of charge. The one thing caught me was my total AC output for the month of Sept was half that of August.

I spent some time calculating from the data and it looks like my AC output does match the math. I was assuming a 50watt loss on the PIP, so ends up 1.2kwh per day and 36kwh per month. Then I assumed the inverter was only inverting at 90% efficient, so a little more loss in it. Subtracting the total PV with the estimated values ended up very close to the actual AC output.
