Solar panel queryWe are having new slates on the roof and might have solar panels on top of them at a later date. We need to make sure that the timber is in the right place between the joists. I don't suppose there is a standard width for the solar panel fittings so that they fit onto the battens is there?
I found this but it doesn't answer the question or it does because it suggests that there are no standard fittings.

Dont worry, they put the mounts where the timbers are & then use rails across all the mounts as a sub frame to put the panels on.

If I'd just had a brand new beautiful Welsh slate roof, There's not a way on this earth some ijut would be drilling holes through the slates to stick some panels (solar or otherwise on! )

We have ours held with brackets that are an integral part of the hanging of the tiles. None of the tiles are drilled. All tiles are clipped and nailed.

Quite so Alison, but cathryn is having slates ! - The link provided clearly states that the slates will be drilled (Carefully)

Slates but not beautiful Welsh slates. No way could we afford them.
We don't really want the mount and rail type unless we can have them from a company that's been in business for thirty odd years and can give us a thirty odd year guarantee. All the gales hit that side of the house so the frames have to withstand that as well as the corrosion effect of salt winds. Aluminium is not good at that. Nothings much good at that.
I might go on knock on doors of people with houses in similar positions and see how well theirs are lasting.

They will all be mounted on rails. I dont think anyone will mount each panel individually with 4 mounts when the entire system can be mounted using rails & hence less mounts in total. Less mounts = less points that could leak.
