  • Solar Forecasts significantly over optimistic

Has anyone else noticed that over the past couple of days the WW solar forecasts have been significantly over optimistic?

For example;
According to the activity log for 2025-01-14 23:32:37, the forecast for 15th was 3.9 kWh whereas the actual generation was 1.1 kWh

According to the activity log for 2025-01-15 23:33:03, the forecast for today (16th) was 4.4 kWh whereas the actual generation was only 0.9 kWh.

Up to now the WW solar forecasts have been relatively accurate but to avoid running out of battery I have decided to set a schedule to boost to 100% between 1am and 5:30am until the sun starts shining more reliably rather than risk having to use IOG day rates.

It's not an exact science, weather is often locally variable.
Today's forecast was 6kW, actual solar was 9.3kW ( lucky me😎)
