November’s solar power generation was, as expected, down on the summer months, even on clear days.Note, though, a few days when the panels generated 2kWh or less – a dull, cloudy month. The total for November was 148kWh.
December was no better, even allowing for the expected fall as the solar elevation falls.
The total for December was 78kWh.
The annual picture, below, is broadly in line with the pattern predicted from the solar elevation. There is no data for January, and February’s result is low, as the panels were installed in late February.
Solar power generation is falling now, relative to the summer months, as the days shorten and the solar elevation decreases. Total generation for the month was 214kWh. The pattern for our installation is shown below:
October has not had long sunny spells, so the pattern through the month is mixed:
A total of 336kWh in September. This is consistent with the seasonal fall in production as the elevation of the sun decreases, though probably reduced somewhat by cloud cover – September was a very wet month.
Yet another very wet month, with 143mm of rain (242% of the 2001-12 average!). Cumulative rainfall for the year is 871mm, 153% 0f the 2001-12 average of 568mm. So a very wet year in prospect.Some very wet days, 29mm on 3rd, and 18mm on 12th, but a dry few days from 17-19th.
