Due to the building work on our house we lost the connection to the solar panels for a few weeks, with the result that the figures for October and November are lower than they would have been.
It's difficult to know how much electricity generation we missed out on, particularly as it was relatively sunny for some of this period. At a rough guess we lost between 100 and 150 kwh. Hence, our yearly total is our lowest so far, but would have been about average otherwise.

Summer started well, but gradually got less sunny, only to be saved by some late September sun.

After a poor February, when we generated only 89.5 kwh, we've had a very good March (233.8 kwh) and April (313.1 kwh). This was largely due to the very dry March and April that most of the country experienced.

At the end of each month we record how much we generate. Below is a graph of our month-by-month generation. The second graph shows our total output per year. The third graph shows the average for each month.

In October 2006, with the help of a government grant, we had pv (photovoltaic) solar panels fitted to our roof. These generate electricity. On sunny days we export the excess that we do not use back to the national grid.
Our solar panels were supplied and fitted by the Bristol based company Solarsense. The total cost was £15500, less the government DTI grant of £7000. It will probably take 20 years to pay for itself, but that's not the only reason for getting them. One of the best ways to tackle global warming is for lots of people to make a small reduction to their carbon footprint. Having solar panels does that for us, whilst it also sends the message to others that this is feasible and in the long term it will save us money.

Another good year for generating electricity from our PV solar panels. We generated 2433.6 kwh in the year, despite being the worst December so far (51.7 kwh). All the snow we had didn't help. When it was snowing, we didn't generate anything. Then, because it stayed cold, when the sun came out it took a while to melt the snow that covered the solar panels.
January was better, roughly average for the time of year (79.4 kwh).

In November we generated 90.6 kwh, which was slightly lower than the monthly average.

October this year was the best ever for electricity generation in the month of October, with 199.6 kwh produced by our solar panels. The average for the month is 178.2 kwh.
It looks like this year will be a good one for total electricity generation, although it may be difficult to beat our best year ever (2007).

July, August and September were below average for electricity generation from our solar panels. We generated 262.9 kwh in July, 244.3 in August and 206.2 in September. Each month was roughly 11 kwh below the relevant monthly average.

June was very dry and sunny and as a consequence we had our second best month for electricity generation. We generated 347.5 kwh, which is more than we used in the month.

We had a smart meter fitted this month, which means that we can monitor in real-time the electricity we're using, importing, generating and exporting. The only down-side is that the meter no longer spins backwards when we're exporting back to the grid.
We've also registered with the Feed-in Tariff (FIT) scheme, although we will receive far less per kwh generated than someone installing a system now. This is understandable, as the purpose of the FIT scheme is to get more people to install renewables. Rather than 41.3p per kwh generated, we get 9p, plus 3p for what we export.

May was another good month for electricity generation from our solar panels. We generated 305.8 kwh.

Time again to update our output statistics. March was just below the monthly average at 219.8 kwh, whilst April was excellent, being very dry and sunny, with a generation of 307.6 kwh.

Solar panel output for January and February this year was around average. In January we produced 85.4 kWh and in February we managed 112.2 kWh. March is looking good with eight days of sunshine so far.

With 2009 now over, we can see how much electricity our PV solar panels produced over the year. To view the graphs of the monthly, yearly and average figures, go to the Solar Panel Output page.
2009 was a pretty good year for electricity generation, with a total output of 2429.7 kwh. This compares with 2491.3 kwh in 2007 and 2343.1 kwh in 2008). Again, the summer was not particularly hot or dry. The best month for electricity generation was actually May with a total of 311.2 kwh, out second best ever (the best being 353.3 kwh in April 2007).
