Looks very good.
Which panels have you used? (sorry if you have given this in another thread)
How much space is there above and below the dormer?, I ask as I have a similar situation with a south facing roof that has a large dormer in it limiting my options (and no garage to use).

Looking good.  Don't forget to register on the BDPV database ( http://www.bdpv.fr/index_en.php) so that we can compare performance. |

yes seems a good one. what surprised me no noise from invverter running at 1.9kw today which is about half load. in fact you would think it was not working .only display showing otherwise.  |

All SMA inverters have galvanic isolation as far as I am aware. Jonathan |
