2017 Solar Panel Generation Stats
Another year with a drop in solar generation. Last year saw a slight decline that followed a couple of very good years including the record breaking 2014. This year however is the lowest so far with low figures throughout most of the year. The only highlight did see the last few months receive a little pick-up helped with a November record.
Hopefully 2018 will be a better year for the Sanyo paneled 2kw system.
The chart below shows the performance over the last twelve months.
2016 Solar Panel Generation Stats
Following a couple of very good years of solar generation including the record breaking 2014, this year was a little let down with poor performance over the winter months.
2016 was not the lowest so can’t really grumble and I’m still pleased with the year’s yield from the 2kw system. The chart below shows the performance over the last twelve months.
Poor Solar Harvesting Result
After a poor May, then a great June – we’ve now got an exceptionally poor July 🙁 July 2015 has been the poorest July since my solar system was installed by some 27%.
July 2015 Generation Stats
Month Total: 237.23 kW
Best day: 13.03 kW 25/07/2015
Worst day: 0.89 kW 24/07/2015
Generation per kW/panel: 118.61 kW
Daily average: 7.65 kW
The solar system followed the best April so far with the worst May – so not a good month to report. Apart from March, 2015 had started well with some good solar generation results that I’d hoped would have continued into May. I guess that’s the lottery of the weather – let’s hope the summer will be a jackpot!
May 2015 Generation Stats
Month Total: 257.61 kWs
Best day: 12.54 kWs on 19/05/2015
Worst day: 0.9 kWs 02/05/2015
Generation per kW/panel: 128.80 kWs
Daily average: 8.31 kWs
What a great month April was for the little solar system. It was the best April so far beating the previous holder by over 40kWs. That’s more like it after March being so down!
April 2015 Generation Stats
Month Total: 279.02 kWs
Best day: joint with 13.74 kWs on 19th and 22nd /04/2015
Worst day: 2.74 kWs 02/04/2015
Generation per kW/panel: 139.51 kWs
Daily average: 9.30 kWs
Not the best March but still a good start to the year. Hopefully April, which is usually a good month, will get the average up again!
March 2015 Generation Stats
Month Total: 174.19 kWs
Best day: 10.03 kWs 25/03/2015
Worst day: 1.00 kWs 15/03/2015
Generation per kW/panel: 87.01 kWs
Daily average: 5.62 kWs
After the highest January yield so far from my solar system, February 2015 followed with a very good electricity harvest also.
February 2015 Generation Stats
Month Total: 114.75 kWs
Best day: 8.12 kWs 21/02/2015
Worst day: 0.61 kWs 11/02/2015
Generation per kW/panel: 57.38 kWs
Daily average: 4.1 kWs
After such a great year in 2014 for solar generation I’ve added another chart to show the yield progression over the twelve months. This eventually lead to my Sanyo panelled solar system achieving the best year to date.
Looking at the year and comparing it with the previous three that I’ve been generating my own electricity, it was only June that stood out with an increase of 28 kWs. February and December also saw an increase. So, although a few record months, but no overall best month or day gave me the best year to date!
