With how hot it is now, summer actually seems worst for my solar/storage energy use situation. I don't generate much more solar now vs. Winter due to summer gloom (cloudy till 9), but use tons more of power now.
During the sunny winter months, I'd generate like 40 kWh or so and use < 20kWh everyday (no need for AC). Now, I generate like 45 kWh or a bit more, but can use 40-50kWh if I decide to charge the EV that day.
I think if someone tried to live comfortably in all seasons, you cannot really rely on only solar/energy storage (batteries) due to multiple cloudy days or fires (in CA). Best off grid is still probably generator, big propane tank (for heat and maybe support the generator too if it takes propane) and more solar panels/batteries.
h2ofun runs his house at 70 I think when it's 95 outside. He uses 50kWh+ a day minimum
so his batteries aren't going to last long.
