average August, sunny September!
After an average Sat & Sun at the start of the month, the first full week of Sept was one of the best weeks of the year for us: 19, 20, 21, 22, 22, 21, 20 - 143 kWh for 7 days, and average of more than 20kWh per day. Not bad for Sept when the expected average is 10 kWh per day!
3 weeks into Sept we're now 45% above the PVGIS climate figures for Sept so far and we've passed the expected total for the month (310 kWh) yesterday.
The last 2 days have been quite contrasting - Fri 21st was probably the worst day ever, certainly since we've had the generation log running - 2.6 kWh for the 9 hours we were generating in the day - a miserable average of 0.274 kW per hour and a "peak" of 0.572! Not even enough to run a few bulbs.
Then yesterday, Saturday 22nd was great - sunny, windy, a little cloudy and a total of 20 units for the day - that's more like it!
There's a week of the month to go but we're certainly on course for passing August in terms of generated units (377), and possibly June (426) and July (429) too!
Oh and at the end of August we were 5% up on predicted figures, not bad given the Met Office AnomAct figures are out for the month and showed ~100% of the average sunshine for our area.
We've now passed a nice round figure of £ 1500 Feed in Tarrif earnings, although some of that will only be paid once the first 12 months are finished & our next reading goes in on 22nd Nov. We're also only 100 units short of the predicted total for the year - 3434 kWh - with a reasonable week we could reach that next weekend with all of October and 3 weeks of November still to run. Not the sunniest of months but certainly a nice bonus of perhaps 5-10%!
