A typical solar PV system would generate between
2 and 4kw of electricity.
Of course the bigger the aray the more you generate and the bigger your income.
In theory a 4Kw aray could produce enough electricity to supply the average households energy supplies for a year.
In reality it is not practical to depend entirely on your own electricity generation. you would need a large bank of batteries, which are both polluting and expensive, to cover the times when the solar system isn't generating electricity, such as at night time. to cover times when consumption is high you would have to overproduce at other times.
The solution is to sell overproduction back to the national grid and utilise what you need from your own supply when it's available.
Using this alone it would produce savings of a few hundred pounds a year and the system would take decades to repay, an may never cover it's costs.
This all changed with FITs, now you could be looking at a total income and savings of around £1700-1800 a year. click on the 'FITs, how does it work' tab above for more info.
