I agree with rooftop residential solar. The cost per kW is high, each site is fiddly and requires far more labour and paperwork than the extra cost of adding 4kW of solar panels to a large grid scale one.
But plug-in solar bypasses most of that. The cost to the government to allow someone to buy and install a panel on their balcony is effectively nothing. A single 800W panel is not interesting, but the aggregate effect of 10% of households buying an 800W panel at the local shop is an extra 12% of installed solar capacity.
Admittedly that's less than the annual growth rate right now. But it's also almost free.
In the EU build time solar roofs overlaps with utility costs but up to 1.5x , and retrofit is say 2x.
To give context. In the EU adding solar to new homes is cost competitive with running existing(!) nuclear plants. In the US only utility scale is competitive with that.
Retrofit rooftop solar is about the same as new nuclear in the US, retrofit is 25% cheaper than new nuclear in the EU.
As a CPA child, you should understand that the same money is very different when it comes out of a different account.
(everyone watches two critical numbers, income tax and government deficit, so the #1 priority is to hide capital spending somewhere else, in this case by moving it to buyers of new homes)
They might not have much of an impact on property values (certainly no more than the plethora of existing building regulations). But we shouldn't be surprised if as a result people vote for a candidate whose campaign promise consists of picking up a grenade launcher and blowing up windmills.
Even moreso now, because PV is now cheaper per square metre than tiles or fences, even if you don't hook it up to the grid afterwards.
On the other hand, this is the UK so maybe. They did Brexit and somehow Farage hasn't been deported for the consequences.
