Generating your own energy

[alternative-energy]

Not really investment info, but I though that you guys might be interested if the realities of domestic energy generation.

 

We have a 3.28kwp Solar Photovoltaic System.

I have just come to the end of my second year of generating electricity.

Last April I had an import/ export meter installed and as I am sending my yearly electricity meter readings to my electricity supplier, I thought that you guys might be interested.

 

Export DAY for year 2421 kwh @ 15p per kwh £363.15

Import DAY for year 949 kwh @ 15p per kwh £142.15

Import NIGHT for year 433 kwh @ 4p per kwh £ 17.32

 

Net return £203.48

ROCs ( renewable Obligation Certs)

received £150.00

 

Total received from Electricity company £353.48

 

 

My Gas Bill for the year is £322.

 

So the Solar PV has resulted in us being financially self sufficient in term of domestic energy.

 

FYI

CO2 saved to date is 3541 kg.

The system cost £8600 when installed. Maintenance £ 0 ( though I doubt the inverter will last forever)

 

The payback time at current rates is 13 years.

However as energy prices increases due to Peak Oil and associated issues, I expect that the payback will decrease.

So you are connected to the grid and can export excess electricity?

 

How much do you think solar varies between different parts of the UK?

 

And are you in a sunnier area than average or not?

Yes I'm grid connected.

See the solar insolation map. I'm in the south of England but not the sunniest part. That's meant to be Bognor Regis of all places!!
