Bank Holiday Monday was dull and grey almost all day. It was a little less dull around 12:00 but the cloud never cleared that I saw.
Power generated today: 3.580KW
Power generated so far: 51.329KW

Day 10
The morning started bright and sunny, unfortunately the afternoon was interspersed with grey clouds and rain, thus the dips on the graph below (and us having to run out to get the washing in twice).
Power generated today: 6.280KW
Power generated so far: 47.749KW
Day 9
So, the second Saturday we’ve been generating electricity. Today was a mixed bag, but overall generated a decent amount of electricity: 
The dips just before 2pm and 4pm were when we had rain showers, the latter also included hailstones which came down so hard we could see them bounce!
Power generated today: 6.423KW
Power generated so far: 41.469KW
Day 8
Today was dull and rainy and, while the system generated more than on Tuesday (23rd), it wasn’t by much:
Ignoring last Friday, which was only a partial day, here’s a comparison of the power generated each day of the week:
Power generated today: 1.578KW
Power generated so far: 35.046KW
Day 7
Today I was surprised to find that we had generated 5.57KW, as the morning had been very dull, however it had brightened in the afternoon, and this is reflected in the graph:
Power generated today: 5.577KW
Power generated so far: 33.468KW
Day 6
Today was the best day so far for electricity generation. It was bright and sunny almost all day, and you can see from the graph that there were only a few dips, probably just the occasional cloud:
In fact the amount generated exceeded our average usage. 🙂
Power generated today: 7.509KW
Power generated so far: 27.891KW
Day 5
Today was a depressingly dull wet day, as reflected in the graph below where our system didn’t exceed 300 watts generation at any point, started generating much later than previous days, and finished earlier:
Power generated today: 1.392KW
Power generated so far: 20.382KW
Day 4 – back to work
Monday – I was back at work after the past 4 days off. It was a nice sunny day, with a few cloudy spells, as is fairly clear from the peaks and dips on the graph below:
You can see the general curve as the power level increases and then drops off. The curve is somewhat skewed towards the evening times because of our west-facing solar panels.
Power generated today: 6.517KW
Power generated so far: 19KW
Day 3 – the day of rest
Sunday – the day of rest… and even more power generated than yesterday:
The trend of the upward curve is more what I expected, and reflect that it was generally very sunny. The peak generation today was 1.458KW, the same as yesterday. I’m wondering if this might be our system’s peak generation capability – our system is rated as 1.9KW, but that is under ideal test conditions and nature is rarely that perfect. My guess beforehand was that we’d probably get about 1.5-1.6KW at best.
Power generated today: 6.186KW
Power generated so far: 12.473KW
Day 2
So, day two – Saturday morning. I was a bit excited to see that it was already generating power as I had breakfast. From the graph below you can see that there was a duller period from about 1pm till 4:30pm:
I changed the graph just to show daylight hours so that it is easier to interpret. I was very impressed with the peak of 1.458KW at about 16:40 and the couple of slightly lower ones that followed.
Power generated today: 4.576KW (which is approximately what I have estimated our average daily generation across the whole year will be).
