Regarding Solar PV at RVF towers - I think what the companies are charging for PV arrays in the UK is appalling. Here in West Australia, kw for kw, Solar PV arrays are about 1/3 or less of the UK price. Rip off Britain yet again.

RVF,
My rule of thumb for UK domestic PV at the moment is £1/W+VAT for a 4kW roofmount system using B-grade kit, or a bit more using A-grade kit. Note VAT is 5%. Here is one I costed recently for friends & family using A-grade kit. These are standard prices, no "mates rates", and are for professional MCS installer, (not me!). I don't recognise your comment about commodity panels, all this is commodity stuff:
4kW TOTAL = £4530 + 5% VAT = £4756 plus scaffolding (see later)
The preferred A-grade SolarEdge inverter can support up 5.7kW, and has a built-in software controlled export limiter. What that means is that this system could add extra panels easily without needing to buy another inverter, and so the cost for a 5.7kW system would go up pro rata except the inverter, to become
5.7kW TOTAL £6157 + 5% VAT = £6465 plus scaffolding (see later)
For a bungalow install no scaffolding is required. For a house install scaffolding is required, allow £550 + 5% VAT = £577 for budgeting purposes
So total estimates for XXX which requires a roof install & scaffolding would be
4kW system £4756 + £577 = £5333 inc VAT (i.e. £1.33/W)
5.7kW system = £6465 + £577 = £7042 inc VAT (i.e. £1.23/W)
What are the corresponding Australian fully-installed prices on a domestic roof at these scales ?
