Generated and imported electricity data for 2012 with monthly summaries below, also graph of weekly gas usage over the years.

This year was one of the wettest years on record, all this cloud cover gave the worst result since my system installed with annual total of only 1514 kWh generated. A total of 852 kWh's were imported this year, approx 56% of the amount generated by the PV. By March 19th 2012 we have generated as much as imported this year, over a week sooner than last year as February and March were very sunny.
Overall we still ended up at 95% of 1600kWh target.(see monthly data chart)
