You save money on your energy bills because solar panels on your roof generate electricity that you can use in your home. As a result your bills will be smaller.
Meanwhile the government guarantees you a fixed price per kW hour of electricity you produce, whether you use it or not, via Feed-in tariffs. This price depends when you install your panels and connect to the grid, but it currently 41.3p per kWhr, and is guaranteed for 25 years.
On top of that, your house is likely to increase in value because it is more sustainable ( and cheaper to run).
Lastly, with around 50% of your electricity coming from the sun, you and your family can halve the amount of carbon you emit through your electrical goods, and so contribute to the government's target to cut carbon emissions by 20% by 2020. And that's before you start to switch off the lights...!
This can only be achieved however, if you have a suitable roof.
