Solar panels in Currys

There is a friendly article in the guardian by Lucy Mangan today on Currys starting to sell solar pannels for home electricity in four of it's branches. They can generate 40% of a households electricity needs, over the course of a year so they can produce a greater percentage of the needed juice in summer than winter when you have to relie on the grid. Obviously currys think that there is a market for these things and like good capitalists have moved to exploit it. However I am not going to part of it, you see they cost £9000, my flat is powered entirely by electricity but at that price it will take 22 years for them to pay for themselves in the cost saving on my bill. So at the moment I will wait for the market to reduce the price to something a little more affordable.
