12V DC wiring for LEDs around the house (for solar use)

I AM living there since 25 years.

Merely answering your silly point.

I have 2 12v battries in series. I could harvest one of the batteries to get 12v. I could harvest other battery for other section of the house. This way i'll have roughly balanced 12v loads on the batteries.

That will be a big mistake. You batteries will NOT stay balanced. If you want 12 volts from 24 volts get a DC to DC converter.

Also, as I mentioned previously, the voltage of a 12 volt battery varies quite a bit depending on the charge-discharge cycle. With a DC to DC converter you will have an unvarying 12 volt supply.

Aha! I see your mistake!
