So that's one vote for fix all tiles as per specs & the solar instal should be fine I take it

Yes that's exactly it, I'd only save around £500 on tiles if I went Integrated but I'd gain around 3kw on the system if I went for On roof. I wasn't even taking into account the much debated efficiency loss of integrated which most seem to agree is around 10% but I know there are many who'd argue differently. Just for anyone who doesn't get it here's a very simplified version of what's happening but I've rounded the numbers: Max Budget £13,000 = 15kw best on roof quote or 12kw best Integrated quote.

I'm really not interested in an integrated vs on roof debate, for my maximum budget I can get a system that is 30% bigger if I go on roof.

Yes I knew there'd be people who get caught up on the Integrated thing hence why I laid out the fact that I have done the calculations on the many quotes I've had & for my maximum budget it works out that I can get 30% or more Kw per year from the On roof quotes & I'd only save around £500 on tiles. I do have a calculator & I can do maths so just take my word for it as I'd rather not derail this into an Integrated vs On roof debate. Not sure why the house would be unsellable if every single tile wasn't fixed as every other roof in my street is built that way & I wasn't saying that was the way I wanted to do it either, I was merely asking for some friendly advice on the question I posted.

Hi I have two 64 sqm roofs on my property, last year I completely stripped one of them & slated it myself, which looks very nice but took me ages & cost a small fortune. This year I'm stripping the other roof but I'm also getting solar installed so thinking some sort of riven look tile as 90% of the roof will be covered by solar therefore I can't see the point in the extra expense & time req for slate. Before anyone asks I have done a LOT of research & calcs on integrated solar panels, unfortunately my budget is extremely tight & I can get around 30%+ more electricity production for my budget with on roof panels (had many quotes) & I'm a high electricity user so every Kw counts! This will be the 1st tiled roof I've done so been researching & it seems in the old days tiles were either laid without fixings, or with just the eves & every 3rd or 5th course fixed. Then since BS 5534 every tile is supposed to have at least 1 fixing or 2 around verges etc & some systems even recommend clips & nails on every one of their tiles. Now the comments sections of anything online showing every tile being fixed seems to be full of angry roofers complaining about how this makes it practically impossible to do repairs/maintenance without smashing tiles & breaking off the nibs on replacement tiles etc. So I'm wondering if I fix every tile is it going to cause issues for the solar installers & would they have to start smashing tiles on my brand new roof? I have seen another video where they just knock a wedge under the row above then use a flat crowbar to remove the nail but it looked very "ideal world" & I'm not entirely sure how easy that'd be in real life. Also do solar panels off any sort of wind protection to tiles, which would possibly make the fixing of every tile unnecessary anyway? I'm not looking to penny pinch on a few nails/clips & hammering in nails is no drama to me, I'm just trying to find out what is best for the roof & the solar instal. Cheers.
