This year started bright and then had a good summer but ended with the worst November and December since PV installed, total generation ended up at 1588 kWh so only just behind 2014 and better than the years 2007 - 2013. A total of 805 kWh's were imported this year, approx 50% of the amount generated by the PV. By March 6th 2015 we have generated as much as imported this year, over 2 weeks earlier than last year. Overall we ended up at virtually 100% of 1600kWh target.(see monthly data chart) Also gas usage data below, 2015 was well down due to the very mild winter annual total just 2,964 kWhs.
