Hi Boomer, The post said I would need 2.7kW of panels to produce 7kWh per day in Winter. That is an average June figure derived from 10 years experience with an unshaded due north facing system; it includes all the cloudy days and in any case isn't the ideal system everyone can own. The rest of your maths may be okay but it started in the wrong place.
I'm aware that EV buffs have the statistics to show that EVs don't have any more fires that petrol or diesel fueled cars, but concerned that some of the EV fires seem to be spontaneous. This isn't a problem as far as I know with ICEs but would be if your car is in the garage at the time. A lot of the culprits seem to be early Teslas; these were basically powered by torch batteries having NCA and NMC chemistries which have thermal runaway temperatures down to around 150C and seem to be more prone to it when they are fast charged; other EVs use LFP batteries which are around 270C and safer under charging conditions. I pointed this out to DaveSSS in another post and he went quiet... By comparison the self-ignition temperature of diesel is around 210C and petrol is around 250C; neither would ignite in a sealed fuel tank anyway (I proved this to myself when a generator caught fire due to a perished fuel tube, I had a nice fireball above the fuel cap vent, though).
Thanks for your disclosure; I assume the great big diesel also has a pangolin skin dash cover, whale oil in the sump and fits neatly in 4 parking spaces
