Solar maths not adding up

A three story climb might be a bit too much for ladders.

Around here they use a Tower scaffolding which you can hire for £50-100 a day, there is a new 1600 house estate being built with 3 and 4-story buildings just up the road from me, with every building having solar installed using Towers. But they do have some 22mt loaders and a crane, which is handy.

Good to read that solar is being installed on the new builds near you.  No such sensible approach here near me in Surrey.. two new estates have been built and not a solar panel in sight.  So short sighted how much could it possibly cost on a new build when spark's, scaffolding etc are already on site?
The have however installed some EV charging points

Sadly, this was all part of the RE bloodbath* back in ~2015, when the Gov got a majority (no longer in coalition), and the PM suggested getting rid of all that green carp!

The new building standards were cut one year short of PV. There was a nine year improvement, which to be fair was great, but eight years in the last part was cut which related to the CO2 impact. The only way to meet that would have been PV panels, (or possibly a net solution, like a small RE farm to balance the estate).

Your thoughts mirror mine, with scaffolding on site, the roof being built PV friendly (brackets already installed, or in-roof PV), first fix running all the cables, etc etc. Other than the work of fitting rails and the panels, I doubt the other additional labour would be much at all, so really it's just the wholesale cost of all the kit, and bought with economies of volume if a whole estate. What a lost opportunity.

*At the same time, the demand side PV subsidy was cut, then ended. PV and off-shore wind were removed from the CfD subsidy mechanism, planning for wind was made as good as impossible, the insulation and efficiency programmes were changed (for ones that failed completely), and so on. Most of this has been reversed in the last year or two, but I'm not sure if building standards have been lifted (compulsory) yet.

The energy crisis has clearly made house buyers much more aware of the EPC rating. The cost of installing solar on a new build may now be less than the increase in selling price afforded by the increase in EPC rating?

I've got the impression that although buidling regs don't get PV etc into plans, there are a lot of planning authorities that are now making it a condition of consent for new residential developments.
