How do I figure out how much solar energy for emergency power?
We have a new house that is all electric. For efficiency, we did not include any fireplaces. This leaves us vulnerable in the event of a power outage during a bad winter. We live in Central KY, so the winters here are usually not too bad, but we do have times where the temps get below freezing for extended periods of time.
We built the home with lots of insulation, so we are able to heat in comfortably with mini splits. We also have a HPWH, so our hot water demands are hopefully low.
I would like to start researching a small solar array that would allow me to keep the essentials going. Things like heat, hot water, the fridge, stove, and maybe a few outlets around the house for a few lights, charging mobile devices, etc.
How do I go about figuring out how many KWh I need? Most websites say to look at your electric bill to see your usage,but that just shows total usage, not how much could be cut out (temporarily) in the event of an emergency.
My utility company gives me daily usage stats, so I guess I could check and see how much power I use when we are out of town for a few days. That would not tell me how much the stove is using, but would give me the fridge and heat numbers.
