So we've had some quotes and they've basically knocked the idea of having solar PV on the house roof on the head due to the dormer.
We had already been planning to get a summer house at the bottom of the garden so thinking of accelerating that and use it's roof space.
We're lucky enough have a fair bit of equity and putting it on the mortgage isn't excessive for us.
In theory the savings on electric would be around the same as our predicted increase when the tariff changes in September so we shouldn't be that much worse off and might even reduce our overall bills a bit.
Currently on Octopus Go 13.5p/5p tariff and looking like will be 40p/7.5p+ when we renew going on current offerings.
Have chatted to a local garden buildings company and they seem confident they can build one with sufficient strength to handle some panels on top.
So currently awaiting a quote for the summer house, 18wx10d. It's south facing so we've asked for a slightly unusual pent in that it will slope toward the front of the building.
Cable run would be roughly 23 metres from the building to the electric meter but should be able to run along the boundary wall without needing to dig a trench up to the last 1.5 metres.
Want all the inverter/battery gubbins in the summer house if possible. Loses a bit of floor space but we're limited in where we could put it in the main house without a fair bit of work.
As far as I'm aware it should all come under permitted development so no concerns with planning permission there.
Not sure yet what the pent angle will be and my quick math works out that a 30-40 degree pent would add 5-8 foot to the height so doubt that it is practical.
I assume the solar panel fitters could knock up some kind of riser if need be?
Only concern is if there might be any glare from it being lower than a standard roof install. Not so much for ourselves, thinking of the neighbours.
Another consideration; currently have a 2 year old bp chargemaster chargepoint.
Any value in changing it to, say, a Zappi 2 for the solar integration or will it all work fine?
Also going to get a quote for an air source heat pump and/or thermal solar water but that's a much lower priority. The heating isn't that expensive to run, about £370 a year, and I suspect the payback time would make it uneconomical. The main issue is we'd need a cylinder and I'm struggling to see where we'd put it without a bit of remedial work.
