With the Feed in Tariff they will pay for themselves in about 8 years if you are lucky and the Government dont change their mind in March/April time and reduce the amount of FIT- or the installer rip you off with inferior equipment
Check you have a strong roof facing south otherwise dont bother. There is a site where you can check the orientation of your house roof but google maps will do the same thing find your house on the satelite image and check your roof ridge runs east to west- then thumbs up!
10m2 of panel is about 1kwhr of output on a sunny day
75% of the annual output is between April and September so make the most of it using electrical gadgets during the day while you are at work to use the power.
If you can get an export meter that will account for a small additional income when you are out of the house while the sun is shining
Hope that helps
