We have our solar system up and running.
18Kw, 36 solar panels and 49 Kw of batteries.
We can run the house all day and all night with zero electric bill.
At night the batteries only discharge to 75% and then by 10 AM, they are back at full charge.
So great not having to worry about electricity going out or an electric bill.
Total cost of the solar system including installation was 400,000 thb (US $12,300)
