Not sure where you live but we can get by on 14.5kw/h per day including two fridges, security systems etc.
We run a 10kw system and it would be a rare day we get less than 15 kWh out of it, seeing as that is 1.5 hours at full load. 30 - 40 kw is more typical, peaking out around 60kw.
That is *very* good data to have, thank you. So on an average day you get about 4 solar hours of light, with a peak of 6 solar hours of light. That matches my observed values here with a much smaller system (~1kw) on a grid-tie/battery reserve.
I've noticed the fridges are the big power pullers (aside from AC, which in a disaster I am not running) not because they pull a lot of juice but because they pretty much always pull it. I should put a Kill-a-watt on the fridge again and see just how much power it pulls in a day, in fact I think I'll do that after measuring the idle current of Antminers (for another thread).
How big is your battery array? Mine currently is 200ah*24v or 4.8kw total. My solar array is about 1.2kw total (single crystal panels so pretty efficient) and my inverter right now is a 700 watt UPS converted to run on external batteries with a Matrix/5000 that can be used if I needed a really high drain load.
If I'm running my house in emergency mode it's about 4kw a day of power used. Which is on the edge for my system: Given I can only generate about 4kw of power a day with the panels I can run for a day with no solar power and even then it would be difficult for me to "catch up" and charge the batteries to 100% with solar alone.
My secret weapon for that is the car: A 1kw 12v battery inverter attached to a car can charge the batteries to full in a couple of hours. Having a hybrid in this case is *really* cool, as you can charge off the hybrid battery and the engine only has to fire up to charge the hybrid pack (which it can do quickly and more efficiently than running 100% just to spin the alternator). A bonus is you have a 10-20 gallon rolling fuel tank that you can also drive (at 40mpg) somewhere to tank up on fuel if needed.
So as long as civilization doesn't completely puke I'm ok. Really. Interesting. Stuff.
