November PV Solar Panel Output Performance Update

 With a late surge as a result of a brilliant last day to end November the panels gave a final output for the month of 53.02 kWh. As the panels were commissioned late morning on 18th November this was produced over 11.5 days so the estimated production for the whole month of November would be 138 kWh.

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.
