So, how are solar PVPs fixed (proper and cowboy) ?
Driving through my village today, I glanced up at some monstrous PVP
installations about the size of a football field on a couple of roofs. It occurred to me to wonder how exactly these are fixed to the roof underneath, and I'm thinking that there is probably an industry 'proper' way, and a 'cowboy' way. When I looked at these installations, they seemed to be spaced a good several inches above the tiles, which were 'standard' concrete types. Given that in general, these are 'loose-laid', and the PVPs are presumably fixed directly to them, does this gap between the tiles and the panel underside not represent a serious wind hazard ? It actually doesn't take a particularly high wind to move loose-fitted roof tiles on their own, so I'm thinking that with a bloody great sail above and fixed to them ... ? Arfa |

I know that the array that was installed on the neighbour's tiled roof was done by installing metal work bolted thru the tiles into the battens behind the tiles. I doubt anyone screws them to the tiles themselves, even the worst of the cowboys. |

Arfa Tiles/slates are removed and pedastles are fixed to the common rafters. The tiles are put back round the pedastles trimmed as neccessary with lead flashings. Rails are fixed to the pedastles and the panels are fixed to the rails. You are right, there are cowboy methods. One is they drill through "fake slates" and fix to the intersection point where a batten crosses a rafter. The pedastle goes on top with a rubber seal. This may be fine if the hole is not near a perpend, but if it is the roof leaks. You can also get integrated systems that replace tiles. They are less efficient as some cooling effect is lost. (They generate more in cool weather.) More suitable to new builds. Thinking of getting some Arfa? You better be quick, the rate is being cut to £0.16 on Aug 1st 2012. There is no guarantee the price of panels will fall as it did last time there was a big cut. |

I gather somewhere in Surrey there is a dispute going on where an installer
fitted them on a thatched roof, and now the planning folk are after the householders guts for spoiling the look of the area. These must be fastened inside the loft, so I dont thing people need to worry about the fastenings as long as the underlying structure is solid in the first place.

You don't need planning permission unless it is a listed building or conservation area or bigger than 4Kwp or projects above the roofline. Are all thatched cottages listed? Could be a new building I suppose in which case no recourse. |

It's doing OK, thanks. Could be better, but paying its way, which in today's climate is probably about the best you could ask for. All the usual problems with staff reliability, and customers who can't read a menu ( do you do fish ? Errr no, we do burgers ... The chip shop is 4 doors down ... ) Got some new varieties though, and now doing onion rings as well. Also cheesy chips, cheesy bacon chips and chilli chips. All very popular. Counter is still standing and undamaged, so I must have got the design and construction of that right :-) Thanks for your continued interest. Appreciated Arfa |

Am I right? Nearly. The weight is mostly taken by the bracket. Chris -- Chris J Dixon Nottingham UK Have dancing shoes, will ceilidh. |

The underside of the tile on top of a bracket has to be cut away or it won't lie flat against it's neighbour. The brackets have thickness you know. |

The underside of the tile on top of a bracket has to be cut away or it won't lie flat against it's neighbour. The brackets have thickness you know. The tiles over the brackets sit a few mm higher than their neighbours. With that design of concrete tile, it is barely perceptible, and is of no consequence.

The underside of the tile isn't flat. It has nibs which sit in the tile below and so there's a gap through which the bracket can pass. Grinding tiles is not acceptable. -- F |

Tiles (apart from slate) are not known for their engineering grade flatness! -- Tim Watts Tiles concrete tiles have to be very accurate or the roof will not end up square. I sawno trace ofany upstanding tiles on the youtube video. The reason is that they want the process to appear as simple as possible. There are three PV arrays within 50 yards of where I am sitting including my own. I have watched them putting all of them on. Interlocking tiles have to lie flat or the ridged side ledge will break off and the roof will leak.. |

Gaps are kept to the absolute minumum in all designs in order to keep snow etc out. |
