Why electricity bills are cheaper ? / Solar power vo.3
There is a mechanism for that. I will explain below.
1. What happens when solar power is introduced?
With the introduction of solar power, all equipment that requires gas (kitchen stoves and water heaters) becomes electrical equipment.
Therefore, there is no gas charge. As a result, the introduction of solar power can significantly reduce monthly utility bills.
The mechanism is that the electricity generated by solar power is sold to the electric power company.
The money you sell will be your income.
Please check this out for details.
2. Monthly required payments
Monthly payment is not limited to house rent (housing loan if you buy a house). There is always a utility bills (electricity, gas, etc.)
It doesn't matter whether you live in an apartment or have your own home.
This means that if you can reduce your monthly utility bills, your total monthly payments will be cheaper.
Please refer to the simulation below.
A. Current situation (living in an apartment)
・ You live in an apartment for 50,000 yen every month with four family members.
50,000 yen (rent) + 15,000 yen (electric bill) + 11,000 yen (gas charges)
= 76,000 yen (total monthly cost)
B. Future situation (living in a house with solar power) * In case of 6Kw solar power
・ You live in a new house for 63,000 yen every month with four family members.
63,000 yen (housing loan) + 21,000 yen (electric bill) + 0 yen (gas charges) +7,000 yen (solar intallation cost) - 15,000 yen (solar reduction cost)
= 76,000 yen (total monthy cost)
A=B, the result is the same.
This is just an example. This is not always the case.
However, if you install solar power generation for about 7,000 yen a month, you can reduce your utility bill by about 15,000 yen.
In addition, if the electricity and gas costs are higher than in the above table, the difference will be even greater.
It is also possible to install solar power later.
However, if you install it later, years of payment will be shorter than that of a housing loan, and the interest rate of the loan will be higher.
Therefore, the monthly payment will be cheaper if you install it first.
4. Actually, you don't have to worry about monthly payments.
I think you are worried about housing loan payments as monthly payments increase.
However, if you think about it (including utility bills), after all, monthly payments are not much different from your current life.
I think it's important to think the monthly payments as a whole.
