In May 2020 our solar panels generated a whopping 517kWh of electricity from the 3kWp set of panels. That's considerably more than the previous high of 460kWh produced in June 2018 which has the potential to be higher as the days are longer.
As we're still working from home, any additional electricity generated during the day is very welcome as we are using higher than normal amounts and can easily schedule washing machine loads at peak times.

Fortunately the days have been hot but with a cooling breeze which may have helped maximise the electricity produced.
