Summary page from the LCOE report. New build wind and solar are cheaper than other forms of generation; new build wind and solar are also cheaper than the marginal cost of production of coal, they are now nearly cheaper than the marginal cost of production for nukes and CCG.
That’s pretty damming for the cost of domestic PV. I’m sure it can be justified in other ways, but the cost of the energy isn’t one of them. Independence from the grid can be a good argument, but greening the grid is a better argument.
You’ve got no chutzpah, your organisational skills are lacklustre and your timekeeping is abysmal.

Not necessarily, as those are costs of generation only and aren't retail prices of electricity, which include distribution costs, return on capital etc.... So if you are paying over $147-$221/MWh (ie: 14.7-22.1c/kWh) retail, then PV can make sense to a homeowner. In a place like Australia, with high electricity prices, lots of sun and an efficient installation process ($1-$1.5/W), rooftop solar is being deployed at insane rates, with 15GWs from over 2.6 million systems to date, with 360,000 installed last year alone.

Installing solar when you build a house or replace the roof will be much cheaper than doing it post-facto, as you have scaffolding and people crawling around up there already. Which is why California has mandated rooftop solar on all new builds.

Here it also makes sense: Residential electricity prices are at the upper end of what you suggest, there's a lot more sun, even in winter, roofs last about 25 years without solar panels protecting them and have to be redone regularly at a cost of ~$10k on a 3 bed house, so installation costs are partially offset, and electricity usage is higher, thanks to AC and heating. Grid feed-in tariffs are also higher.

LISBON, Nov 22 (Reuters) - Portugal shut down its last remaining coal plant over the weekend, ending the use of the polluting material for electricity generation and becoming the fourth country in the European Union to do so.

Environmental group Zero said in a statement the Pego plant in central Portugal had been the country's second-largest emitter of carbon dioxide, adding that "freeing ourselves from the biggest source of greenhouse gases was a momentous day for Portugal".

The move comes nine years before Portugal's targeted end of the use of the fossil fuel by 2030.
