I get the part that you have a large family, challenging to handle that as it is so can't necessarily reduce or shift loads during the day. But something seems a bit odd when you look at the YoY comparisons for the three months that are shown (May-July) for both 2022 and 2023. There's a massive increase in usage in 2023, like sometimes 800-1100 kwh/month MORE than the year before - and this is despite doubling the size of your solar array (though not sure if the added solar in 2022, so could be that the increase is even greater than that).
Your EV is not new from the pats year - did you birth a bunch of the young'uns in the past year, and there's a whole bunch of added new usage - washing cloth diapers, humidifiers, monitors, more climate control? Or get a job with a much longer commute - like 100 more miles/day? May is usually not even much of a heating or cooling season, so to use 1100 kwh MORE that month, something big changed besides the weather. Slightly good news is most of the increase was in off-peak, so at least the rates were a bit less painful...
