Last 3 days (if you include todays prediction for tomorrow) the export schedule solar prediction has been well below the actual solar production. It doesn't seem my system setup is incorrect as it's been reasonably accurate since installation last November.
Yesterday I changed solar array orientation setting from south-west to south-east thinking that might step up the predicted vlaue today for tomorrow, but alas no.
Date Prediction from previous day Actual
10/4 11.9 9.4 (prediction Ok'ish)
11/4 7.6 10.2 (prediction OK'ish)
12/4 12.1 24.8 (prediction very low compared to actual)
13/4 10.9 27.8 (prediction very low compared to actual)
14/4 6.3 (prediction for tomorrow looks really low as the forecast for tomorrow is just a bit cloudier than today, so I'm expecting at least 18kWh tomorrow).
