Once they start making an actually roofing material thats also a PV panal, then we are in business! How do the current ones actual fix to the roof? Are there any holes in the roof to support them? - if there are you can bet they sealed the holes with something retarded like mastic or silicone... I wouldn't want a load of holes on my roof sealed with silicone which will degrade with UV... They pay for themselves in 5-10 years depending on who tells you, so how much longer will they last than that? Also these firms that fit the things are mostly on a quick money band wagon (government grants) so I expect the work is not being carried out by Roofers and Electricians but more an adhoc crew proberbly with one sparkie and a load of numpties...

It's only by getting these sorts of project started that improvements will come. Once house-builders are asked to provide solar panels on new-build housing - thereby bringing the process under the aegis of "building-control" regulations - then there will be no 'holes' with 'mastic' allowed. And if Bovis or Wimpey ask for panels to be built to a specific size to fit with standard roofing techniques, the panel-makers will roll over if they have any business sense at all. Likewise if the big firms ask the roof-truss manufacturers to beef up their product - maybe add a number of king-post trusses to enable strapping back to - then d'you imagine they're going to refuse?
"...more an adhoc crew proberbly with one sparkie and a load of numpties.." LOL!
If there's just a sparks and a load of unskilled labour - who's going to tell them what to do? The sparks? I don't think so.
