pv electricity
If your household uses 5kw of electricity in a month will a 5kw solar (pv) system supply your needs? ?
If it doesnt add up that way, how does it?
It depends on your usage patterns compared to the output of the solar PV system.
You’ll need to also be charging up batteries to ride through the nightime hours and days with cloud cover, rain, or other conditions that will prevent maximum output of the PV system.
If your loads cycle throughout the day, there might be enough power left over to charge the batteries.
If your home’s peak load is 5 kW, I suspect that is the mid-day peak demand with the central AC running. In the middle of the day 100% of your PV system’s output will be used to power the AC. You need to have some daylight hours where the PV output can also charge batteries.
I’d recommend a PV system with a slightly higer output.
You also have to factor in the inefficiencies of the inverter and slight losses associated with the battery storage.
Good luck.
