Renewables: "talking 'bout my generation"

Cottage_Economy

Now I have my system in place I can start recording readings.

Alternate sunshine and showers yesterday but reached 3.75 O's by the end of the day.

Morning all - quick favour to ask if I may as I don't have enough data of my own yet.....


Could you let me know how your generation this February compared (in % terms or using whatever numbers you've got) with last February (& ideally the year before)?


I don't want to make any false assumptions based on this years generation during an unseasonally warm (but not necessarily sunny????) February.


Thanks, Mike

Hi Mike. My target for Feb is off PVGIS, and although I have some shading, I use the 'whole' number as my reference point, I don't use a lower target.

Year - Feb - whole year %

2015 - 107% - 106%
2016 - 117% - 102%
2017 - 74% - 99%
2018 - 142% - 104%
2019 - 129%

Taking this year as 100% I get:

2018: 104%
2017: 55%
2016: 71%
2015: 65%
2014: 74%
2013: 63%
2012: 85%

So 2019 was the second best February.

Would it be roughly correct if the time had been set (by default) to midnight at the moment of its commissioning? That would be indicative of the electrician forgetting to set the clock - unless, of course, you misread it and it was really 39 Watt hours

Don't you have the generation meter fitted as well i.e. the one the meter reader is going to look at? The reading at this time tomorrow minus the reading now will give tomorrow's total.

I found the clock setting and it's correct. I don't think I misread the generation figures, but I'll put it down to being too early in the morning for the brain to be working.


2.6 O yesterday. Only 0.22 so far today, but it has been thick cloud all day.

Best day of the year so far with 3.89 O for 152% of daily PVGIS. :j

Suggest that you speak with your installer with regards to the anomaly your experiencing with night time generation.

Another, but not quite the obscene result for me..3.48 O's..:rotfl::)...

Thanks for responses to earlier post re: Feb generation - helps me plan water heating / battery charging
