[QUOTE="binky, post: 523853, member: 490"] lovely big back roof, although not facing the best direction, I would be tempted to max the rear roof array and have batteries. You do have a south facing aspect that you could get a small array on, 4/5 panels, but that would add to the cost of scaffolding. The one thing I really don't like is Rosemary tiles, which you have, effing things are about as strong as a Rich Tea biscuit, so, to prevent issues down the line, ie a tile stressed during installation fails 5 years later, I would be possibly looking at the GSE in-roof system. It does add to the costs, but is a better long term bet for that roof. The other reason I would target the rear roof, and ignore the side, is that we do tend to get clearer air in the mornings. The panels will still be generating at a low level in the afternoon, but from ambient light rather than direct sunshine. Reckon your rear roof is good for about 15 of the larger higher wattage panels ie 450w, maybe the so that's an array of 6.7kW from which I would expect you to generate around 850kWh per kw of panels.
