So 3.01kWh panels have generated an average per day of 4.61kWh. This compares well to the SAP calculated estimate of 3.6kWh but is below the figure quoted by PV Solar UK of 4.87kWh which seems overly opimistic - much the same as the rest of their figures!
|Monthly PV Solar Panel performance for November|
The 11 days of November that the solar panels were generating were a varied mix of sunny, cloudy and a couple of rainy days so appeared to be a typical spread of weather although we are now far more attentive to whether the sun is out or not!
It is now quite noticeable that shading has a significant effect and the graphs produced by the inverter clearly show the drop in output as soon as the panel area has any shade falling on it. I will post some eexperiences of how the shade affects the solar panel output later.
