Now I can finally figure out how much power it generate per year!

Newly built in August 2015, Panasonic's energy farm is attached along with sunlight.
The composition of sunlight and ENE-FARM is like this.

year in 2020.
it is the fifth year since we started generating solar and energy farms, but we have not been able to see the amount of power generated properly due to a problem that HEMS (Home Energy Management System) cannot see normally. Even with

, we were able to successfully fix it in 2018, and finally we can grasp the power generation situation for the entire 2019!


Here is a graph of enecoco (HEMS) showing the annual power generation.

Solar power generation (2.3kW): 2,811 kWh
and other power generation (Enefarm): 2,481m3
total: 5,292 kWh

, i don't know if it is correct that the amount of power generation is in the unit of m3, but the total is the value plus both, and it is 5,292 kWh, so it seems to be good to think that kWh.

other power generation of the other of the house is enefarm.
the maximum power generation of ene farm is 0.7 kW, but since the time that power generation is longer than sunlight, as a result, it is generating an amount of power that is not so different from sunlight.
the time our energy farm is generating power depends on the season, but it is usually from 6:00 a.m. to about 10 o'clock in the evening.

With 2,811 kWh of solar power generation, evpower can be completely covered.

The annual power generation of sunlight is 2,811 kWh, so it's a bit undiminating.
our car is a leaf of an EV (electric vehicle), so let's calculate the amount of power applied to the leaf for a moment.

, the average annual electricity cost is about 6km/kWh, even if it's a bit harsh. I run about 1000 kilometers a month for commuting and leisure
, so I'll need about 16
7 kWh of electricity in the month of 1000/6 to 167.

The battery capacity of our leaf
is 40kWh.
If you run until empty every time, charge it four times. Because it becomes a calculation, it seems to correct it by this calculation in the sense.


If you fix it over the year, it is calculated that the amount of power of 2,004 kWh is required for
167 x 12 x 2,004
years.

That means that even with a slightly scathing 2.3kW solar panel, it actually generated 2,811kWh of electricity, so it was completely the amount of electricity that the EV would cover! !

In fact, the power generated by solar power is consumed at home and other than that, so we don't run EVs just by solar power (Nissan's rapid charging is often used), but to be honest, it was a little surprising that we were generating electricity from our reef simply by solar power.
It's
solar power.

Cooking is electric and uses 4,886 kWh of electricity per year

All of our kitchens are electric (IH kitchens).
The bath is made from boiled water at Ene Farm. Compared to households that use gas, the power consumption is high, but the annual consumption was 4,886 kWh.
As a measure of the electricity bill, it is about 10,000
yen a month because it is
131,930 yen.



If you are using IH, I think it is reasonable.
(Actually, i'm generating electricity elsewhere, so I get money for electricity as a

, if you don't generate power, you're consuming this much power, and it's all over. I'm glad to know that.

I'm not usually sure how much (environmentally positive) it is compared to the case where I don't generate electricity, because I'm generating power and consuming it as electricity used at home.

The balance of electricity bill is plus 17,013 yen

We were able to understand the balance of electricity sales and electricity purchase over the years. I think that the calculation of the
amount is not so accurate, but I think that the calculation of the amount of power is almost correct.

, the electricity bought from the electric power company (TEPCO) and the electricity sold to TEPCO are more likely to sell electricity, so in the end
, it was a positive
.17,013 yen.

this balance does not include the gas bill, and since Enefarm generates electricity using gas, it is not simply positive as a whole. By the way, the gas bill is about 8,000 yen on average per month.


In the cold season, the floor warms are also used quite a bit, so the gas bill is a little higher in conjunction with Enefarm.
I would like to summarize the annual gas bill usage.

I felt the greatness of solar power generation.

In the fifth year since I installed solar power generation in my house, I was finally able to know the amount of power generated per year. to be honest,
didn't have the image of generating electricity so far

;).
Such, because it is a power generation that lacks a little sense of stability, too much, it is power ingress gun gun! I didn't feel that way.

However, when I looked at it over the years like this, I could clearly see that they were definitely generating electricity every month.
it is a little surprising that the difference in the amount of solar power generation is not so different between summer and winter.
If the temperature of the solar panel becomes too high, the power generation efficiency will be low, so it may also be affected.


, the solar panel is 2.3kW, and is it normal to attach around 3kW? Because it is a feeling, it is a little less.
still, it's not like they're going to generate this much power!

Considering the charging of EVs, even if there were no large storage batteries in the house, I thought it would be ants to attach a solar panel such as 4kW or 6kW.
Solar panels are still expensive

, but it's amazing if you have two EVs
;), charging from sunlight, and becoming able to cover the electricity of your house.
, if there is a storage battery of about 5kWh in the house, it is not necessary to buy electricity from the electric power company anymore, and gasoline cost does not cost either.
All the energy will be able to be from the sun!

What was such a dream story is actually coming out of my eyes.
zero CO2 emissions, dream energy, sunlight!
I'm looking forward to many things from now on.
