On paper it was a very sunny year, but this was not the case in all months and in it failed to appear in the key months that mattered (April, May, August and September for example). So whilst it was a good year, it wasn't a great year.
However there were a few milestones - November saw 10mWh appear on the meter. So just under three years since the system went in and the numbers look good. So, as a rule of thumb and subject to decent weather it looks like the system will create nearly one kWh of power per year for each watt of solar panels I have. So that's not a bad figure to aim for.
Money wise, the FIT payments keep coming in - £1600 a year is not to be sniffed at - and it looks like I'm using 70% of the power being produced. I've worked the latter out based on 2 methods:
1) the reduction in my electric bills
2) detailed analysis of the OWL data based on previous usage levels compared with the minute by minute data over a year (i.e. what amount of energy would be used vs exported each minute assuming a 1000w continual household consumption).
Both converged to the same number, so that's good enough for me.
Outlook for 2015... well hopefully more sun, more free power and I suspect a year end total close to 14mWh.
