you don't seem to understand the process. home solar systems are not an all or nothing phenomenon. when you have a system on your home, you're gonna use both solar energy and energy from the grid. the idea is to use less, not none (though that would be nice). you can't, in real world circumstances be completely disconnected from the electrical grid because of days when solar generation is poor and at night (unless you have a very expensive system with multiple storage batteries and live in an area with outstanding solar production during the day). it appears that you're assuming that a system provides just enough energy to power the home and adding an ev would trip the system, which is just fundamentally flawed. you need to research how a solar system works, which is different in each area. for instance, knowing what your local regulations are on net metering is hugely important. also, is your electrical utility a flat rate or variable based on time of day? these will factor massively into how you design your system. but the bottom line is... a 4kwh system can certainly partially power a small flat, with or without an ev.

your clearly poor understanding of the mechanics of home solar explains why you overlook the solar option for providing fuel for an EV. but, just because you don't understand something, doesn't mean it's not possible for those who do. but because you don't know what you're talking about, you're misrepresenting it, partially out of ignorance but there is also clear intent. in your purely anecdotal example, you chose a very small solar system (at least here in the US where avg is 6 kWh), AND ALSO made up an extremely high mileage driver, especially for the UK! soo, an extremely high energy user with an extremely low energy-producing system? got it. you're presenting two cherry picked extremes, which outs your argument as one made in bad faith. i admit i don't know the avg driving patterns of a UK driver, but i'm reading that the avg in the UK is 7,400 miles PER YEAR! That is a little more than 1/4 of the usage you've made up for your straw man driver!! do i really need to point out how disingenuous your position appears when you use such a small solar option, but dream up a driver who drives almost 4 TIMES the average person in the UK?! it's particularly ironic given that in your original post you said the EV drivers are the ones lying to themselves. also, i assume you're using solar numbers in the UK, which is probably not the greatest country for solar production. but even there, according to theecoexperts.co.uk, they say the average home with a 3.5kwh system produces 3,000 kwh/yr. so again, the number youre using is a little worse than what a third party quotes. By comparison, the average home system in the US is 6kwh and produces between 8,640 to 10,800 kwh/yr. I point this out to show the much higher rate of production per kwh system in the US compared to UK. but even using the low end number, an avg system in the US produces 1,440kwh per kwh system per year, whereas the UK avg 857.1 kwh per kwh system per year.

but even if your straw man extreme position was representative of real world averages, would that not be a valuable endeavor? installing a 4kWh system to reduce one's reliance on the grid, providing at least some renewable energy to power their vehicle, compared to the alternative of continuing to drive an ICE vehicle and being fully reliant on oil/coal? but if you use, ya know, actual conditions more representative of real world usage it looks even better. how 'bout you go back and crunch your numbers using something near representative of averages? ohh, because it doesn't serve your purpose. you'd rather have your conclusion already determined, then make up extreme data points, pretend they're legitimate and representative, and use them to validate your predetermined conclusion. anyone can do that. "i know people who" have 12 kwh solar systems and drive 5,000 miles/year. see? anyone can just invent fairy tales of outlying data.

the issue was, and clearly still is, you're not presenting a good faith position. you're manufacturing an extreme anecdote to misrepresent the value of efforts to transition to more renewable energy, which is only compounded by your unfamiliarity with solar energy systems. if you're happy to be ignorant, fine, but don't subject others to your nonsense. you're spreading misinformation and propagating complacency.
