This is the data for September showing how early the panels started generating and how late they finished as well as the maximum peak output during the day. This is added to automatically each month as the data builds up and gets loaded.

Average for September is 314.0 kWh of solar electricity generated.

Value is based on average of 10 years of solar generation data with minimum of 276kWh and maximum of 354 kWh

September Compared Year on Year for UK Solar Panel Generation

The monthly data shows by year the solar electricity generated each September and peak output produced by south facing solar panels in England.

You can see the difference between each year and how much solar electricity was generated compared to previous years. Each month is also available individually

January February March April May June July August September October November December

The data is interesting in how consistent some figures are across the years whereas some vary hugely. For example the earliest/latest start times are very similar but the monthly solar panel electricity generation can vary by almost 100%
