But surely that is a flue for a boiler or some other fire etc, not a sewer vent in the photo? You cannot put an AAV on a flue as far as I'm aware.

An Air Admission Valve is basically a non return Valve and YES it is fitted at the end of a Soil Vent. I assumed that the vent shown in your photo was a soil vent not a boiler flue.

I got a quote with micro inverters incase I can't move the chimney for £6600. What I don't understand is the surveyor has put a shading factor of 0.9 on the quote bringing the estimated generation down from 3057kwh to 2751kwh. Is he just being conservative with the estimated output ? The roof only shades early morning and would only effect 2 panels, I thought micro inverters would help with the shading ?

Heres the finished product, the flue was only moved yesterday. Have to say that shading on the top row of panels knocked generation by 50% in the morning so it was worth the £250 to move the flue. managed to get the paperwork done before the end of march deadline. Genertated just over 300kw's in April on a 3.64kw south west facing system.

Looks great, glad to see that moving the flue wasn't a problem. What type of panel did you go for in the end?

First year anniversary up, I have generated 2934kw compared to pvgis forecast of 2850kw and the installers 3050kw forecast


I had 6 weeks last year before the chimney was moved so some shading affected it then so it will be interesting to compare april's generation to see what effect shading had.
