Solar panel performance – 2010

It’s a bit rum writing a post about this so many months into 2011, but it is supposed to be an annual thing, after all!

Solar panel performance 2010

As the yearly data graph shows, despite feeling a little disappointing, last summer, or at least the year as a whole, provided more hot water through my solar evacuated tubes than any previous since the installation was put in.

3,999 kWh of heat is just ever so slightly frustrating. An extra hour of sunshine on Dec 31st and we might have had 4,000…

Nottingham Energy Partnership have an Energy Costs Comparison table. I neglected to look at it last year, so will have to use the data from last month now to estimate the financial value of the heat we got from the sun. At 4.40 pence per kWh, the value adds up to £175.96.

The running total to the end of 2010 is therefore £451.68.

There are all sorts of flawed assumptions being made to come to that figure, so take it with a fairly large pinch of salt.

But if you are considering a solar panel of your own, whether for hot water or to generate electricity, and you live vaguely near Nottingham, do please get in touch with Sungain at Nottingham Energy Partnership, who would be delighted to let you know what to do next. You can also follow them on Twitter, and they also have a very helpful service on their website that lets you compare your electricity and gas tariffs and see if you can save money.

And a declaration of interest: I’m on the board at Nottingham Energy Partnership, where they very kindly describe me as an “energy expert.”
