I am completely new to the solar game and while I have read and researched I am still not confident in making the decision . I had few companies coming through to provide the quote but only 3 really communicated properly.
While my house extension has plenty of roof space to install solar we are unable to as they are self supporting roof panels unable to support weight of the solar panels. Also my warranty and insurance would be void should something happened to the roof. So old part of the house and carport are the only available space to install solar .
