My solar forecast generally looks more like my panels are facing south while in reality they are facing north-west.  
The forecast peeks around 13.00h while my panels peek around 17.00h.

Is there something i could do to correct the forecast? (besides turning my house southward)

Perhaps extra settings (azimuth & declination) can help the forecast.

Did you just recently turn on the solar forecast? It will adapt to your location with time, I believe 30 days is ideal and continues to learn beyond that.
