You'll find that you hit the highest peak when the sun comes out at midday after a shower or period of cloud cover because the panels are cold. On days of full sunshine the heat builds up, reducing the peak generation.0

26.05 kWh today despite an imperfect peak of the curve. Didn't expect this kind of performance from a triple aspect system.
