One of my pet hates the incorrect use of the description 'Solar Panels'. All these things appearing on roofs all over the country are photovoltaic panels which convert the light into electricity which is put back into the national grid, and the household is given a credit against there bill.
They will NEVER payback.....they will have broken long before the payback period.
Solar panels are tubes which are filled with special liquid which heats up your hot water and are used extensively on the continent where its Sunny, and no use here.
These companies offering the Photovoltaic panels are conning everybody along with the Government.
And while I'm on a roll, the companies offering to insulate your house on the cheap by applying for a grant on your behalf..... its all paid for by the Government who are getting the money from the Energy companies....hence the increase in Energy costs. We are all paying for our own Grants !!!!!!!!
Aren't I a miserable git ;-)
