I mean I can get solar on my roof for about $4000Aud and then I pay nothing unless it's particularly cloudy.
But for grid electricity even if the generation is dirt cheap the power company in WA is responsible for covering an area the size of a chunk of Europe with a total population of under 3million.
There are significant distribution costs involved and I suspect even at the prices we pay its subsidised by the government.
$4000 is also pretty expensive; at my 7% yearly interest that's $23 a month. at my number of 0.9ยข per kilowatt hour that's 2600 kilowatt hours per month, an average of 3600 watts. i will be very surprised if you are using 3600 watts round-the-clock average unless you have a machine shop in your garage
so i think you are dramatically overestimating the cost of rooftop solar
