I don’t know how the energy system, and costings work. I want to buy Tesla batteries and solar to essentially not need to use grid power at all, but I can’t really figure out how many batteries/panels I need.
My electricity bill say I have used 25KWHs this cycle, but the power spec says it will store 15KWH/day. Surely this doesn’t mean 2 days of storage would cover my whole bill.
I live in Australia, if that’s relevant
I’m 28 years old, and I have no clue. Pls help!

25 kWH is probably a good baseline for DAILY consumption of a household.
Assuming about 4-5 hrs of insolation (usually a good number), then you’d probably need something like 5 kW of solar power. Added inefficiencies, maintenance and general wear and tear suggest that you double this and a 10kW solar panel system plus batteries that can store around 15-20kWh as a baseline. You might also want to factor in some “growth” if you ever plan to use electric vehicles, expand your home etc.
Anyway, the installations usually come at 1kW, 2.5kW, 3kW, 5kW then usually move up in increments of 5kW (most people won’t do a 16.35kW install/design, for example)
Edit: nevermind this comment, i’ve confused the units. People who replied corrected me.
KWH is kilowatt per hour, it is the power all your devices put together use for one hour of work. Your bill must say about the amount of kilowatts (without hours) to find out how much you actually use. Actually, on one hand 25 kilowatts per month is unbelievably little to me, but using 25 KWH of devices is kinda too much to be real either. So either I don’t understand how electricity works in Australia or your bill needs some further investigation.
