March 2013 Solar Panel Output - Cloudy days ruin Electricity Generation!

Having returned from holiday and found the weather to still be cold and damp it was no surprise to discover that the electricity from our solar panels in March 2013 was massively lower than in 2012.

The total generation shows the full horror!

 

March 2012 : 310 kWh

 

March 2013 : 173 kWh

Yes that is 137kWh less for the month than we obtained in 2012 which equates to over £60 in lost FIT income as a result. The SAP estimate was 210kWh and the PVGIS estimate 241kWh so this was a spectactually poor result compared to the estimates.

The total for the first 3 months of 2013 shows an equally bad picture with 376kWh compared to 599kWh in 2012 giving £100 less in FiT income.
