I really love the look of this kit and have been investigating its use since the beginning of the year. My interest is for use on Scottish slate roofs where there are no battens. Slates are nailed directly to the sarking (close boarding). This makes fitting brackets a little problematic. You can easily use a couple of hundred pounds worth of lead making soakers and flashings to achieve a good job. There is also all the additional labour involved. I reckon stripping the slates, screwing as well as the existing nails in the sarking and fitting the Easyroof directly to it (may need some additional timber reinforcement inside), will be quicker, neater and maybe cheaper, than what we do now.
However, there is one caveat that has so far stopped me. MCS012. Within this there is a requirement for roof integrated systems to meet a whole raft of standards which are already part of the building regs. The one I have issue with is EN-BS 13501-5: 2005; 'Fire classification of construction products and building elements. Classification using data from external fire exposure to roofs tests.' If that sounds a mouthful, reading and researching it can lead to a loss of the will to live.
In a nutshell this European Standard is a bit of a minefield. The tests for the spread of fire are territorially defined. There are four different ones. Which one is used depends on which county you are in. The French use Broof test 3 and the UK Broof test 4. Why this matters is that the test used in the UK is more stringent than that used in France in that it includes a self extinguishing test.
I have met the European Export Manager for IRFTS Lionel Doudaine on more than one occasion and have had discussion and communication with him over this.
During our most recent discussion at Solar Power UK in Birmingham last month, he brought me up to date with the latest position in terms of accreditation of the product. It is currently undergoing full BBA agrement approval. The product would not meet Broof Test 4 due to the material it is made of. BBA have accepted the Broof test three, but this is may put some restriction on its usage.
If you go and check all the relevant bits of regs, this may mean on semi-detatched and terraced buildings there is a minimum distance the array has to be from building boundaries.This may make it unsuitable for certain applications.
When the BBA certificate is published it should detail all of this kind of data. IRFTS are to be applauded for taking the approach they have to getting approval for the UK market. I really do hope that use is not too restricted. Be warned there are numerous other systems out there made of similar material that may not be put through similar accreditation but still be sold. The more the PV market matures the more likley it is there will be greater demand for esthetically pleasing solutions to mounting panels such as Easyroof.
Butt ugly, messy, and unsightly installations are the elephant in the room of PV.
