Isn't that the biggest issue, it's like the Wild West out there at the moment, all the double glazing salesmen seems to have jumped onto the Solar bandwagon.
I really want to do the installation myself, apart from maybe the last connection back to the grid, which as usual is shrouded in the terminology, has to be a competent person, but as usual there is no definition of what constitutes a competent person, the Installers out there will try to convince you that you have to have qualifications, but I don't think that is quite correct, however your provider may insist they are.
We visited the Centre for alternative Tech before we decided what to do and found it very useful, but it did take a bit of looking.
