The last couple of days have been great and I reached a new maximum output yesterday and then another new one today. Yesterday was around 19.5kWh and today was about 20.8kWh.
I am not sure exactly they today was 1kWh better as both days seemed similar. Temperature's were similar, and cloud cover seemed equivalent.
I mention temperature being the same because my understanding is that the colder the temperature, the less resistance, and therefore the more efficient the PV System works.
I paid pretty close attention to the panel output and it was a very steady bell curve that produced over 3.5kWh for quite a while with a quick peak reached at 1:20pm. This doesn't really make sense as you would think the peak would have been around noon. The peak itself was just over 4kWh!
I can't wait till the summer!
