or 225.2 Kilo Watts, if you prefer.
I suppose you'll want to know how to obtain the answer.
To find the area of your roof, multiply 10m by 20m, which will give you 200 m^2.
Since you know the constant from the sun is 1126 W/m^2, multiply this value with the value for the area.
200m^2 * 1126 W/m^2
This will give you the answer listed at the top.
