Month: April 2018

Solar Power for January, February and March 2018

 

JanOur solar panels have generated 671kWh in the first three months of the year, reasonably consistent with the expected annual profile.

January

January was patchy, with a few reasonable days.  We have no comparison with previous years for the monthly total of 94kWh, as the system was not installed until February 2017.

February

The latter half of February in particular was sunny, contributing to a monthly total of 306kWh, with several days over 20kWh.  Again, no year-on-year comparison is possible.

March

The total for March was 271kWh, slightly greater than March 2017.  A few good days, including one at more than 25kWh helped.

Rainfall for January, February and March 2018

The first three months of 2018 have been distinctly wet, with a total of 357mm of rain, amounting to 185% of the 2000-12 average.  The graph below shows the pattern.

January

Total rainfall for January was 161.6mm, or 215% of the 2000-12 average.  As the graph shows, the middle of the month was dry, but heavy rain from the 15th on accounted for the high total.

February

February was drier than average, with only 57mm of rain, or 88% of the average.  The last 10 days of the month were notably dry – a hosepipe ban looked like a real possibility!

March

March more than compensated for February’s low rainfall, with 138mm of rain, or 259% of the average.  Most marked was the 14th of the  month, when 22mm of rain fell in 24 hours.
