I saw some shocking and mysterious electricity bills.

Today I visited the S residence in Eigashima, which I handed over to them a while ago.
I was also happy to receive words of praise.
"I've traveled twice since I moved here, but it was the first time I felt like home was better."
"My child used to not want to come home, but now home is his favorite place."
"Almost all the guests gave it rave reviews"
It was the highest compliment.
One thing that was particularly surprising and even puzzling was the electricity bill.
Currently, a typical household with a family of three has a solar power generation system of 3kW.
Regarding the composition, the most recent electricity bill was in the 3000 yen range.
The selling price of electricity is in the 17000 yen range,
That's a profit of nearly 14000 yen!
It's true that we've recently been in the intermediate season where there's almost no need for heating or cooling.
Even so, it's too cheap. I, the designer, don't know why it's so cheap.
I couldn’t understand why it was coming out.
In the event of an unexpected event such as a power leak, the electricity bill will be calculated higher.
So that situation is not possible. May is the month of the year.
This is the month with the most electricity generation. It's still an impressive figure.
It probably won't be like this every month, but if it continues like this, the internet and cell phones will
Even if you include these, your monthly utility bills may be zero.
Up until now, the 6000 yen range has been the most economical option.
I was quite surprised at how common it was.
