I've decided to go down the solar route with my autosleeper Kingham as it really likes the taste of electricity and I would really like to not have to go chasing the stuff every couple of days while I'm away. After reading a few threads here I'm concerned that the panel will go flying off the roof! I'm thinking that as well as being 'glued' to the roof it should also be attached by 'threading screws' or similar? To those that know about these things, does that sound sensible? Also, can anyone recommend an installer in the North Wales/Cheshire area? Thank you!
