Good thread, glad someone's put this together. I went through much the same rigmarole last autumn when I was expanding my barn setup. From what I found, Signature Solar in the States will ship...

Ha, joining the club of cliffhangers it seems! 😄 @RelayDream solid choice of kit there. One thing I'd add that nobody's mentioned yet — worth double-checking your absorption voltage is set...

@ForestJenny @FormerTeacher61 — thermal bridging absolutely killed us too, particularly where the floor joists met the external wall.

@DefenderAdventure makes a good point about the Voc — worth actually doing the maths on that, @Nobby30.

Roger1961 | 2,341 posts @OllieRoss74 Great start with the Victron kit — solid choice. I'd say 200W isn't pointless at all for a shepherd's hut, provided you're realistic about what you're asking...

@CotswoldNomad — good thinking on the landlord angle. Before committing to roof work, have you considered a portable setup on a ground mount?
