- March should have been 207 kWh but was 281.
- April should have been 306 kWh but turned in a score of 429.
Looking at the charts here, the final weeks of April were astonishing, we had a run of nine days in a row, all touching or above 20 kWh, apart from one freakishly cold dark day on 15 April. The lower illustration is a typical run of days, from April 15 to 21. Even though our roof faces east, the early morning sun gives us good performance. I notice a pattern whereby days often end with cloudier afternoons after a good start - enough to put me off recommending a west roof where an east one is available.
