It all went very smoothly and we now have ten solar panels on our back roof (facing east) with a total generation capacity of just over 3Kw
Obviously the sun does not shine all the time, even on a bright day, and the panels only catch the morning sun, and then increasingly obliquely, but we are managing to generate around 13Kwh per day at the moment, which we are happy with.
During the design stage we went through the financial models but, frankly, that was not the point. We all need to reduce or consumption of fossil fuels (and their derivatives) and this is one way that we could do that.
