Good or bad to store the PV in the batteries?

[sicetaitsimple]

So I analyzed the ENEDIS file, hour by hour, and the file is not good.

Over a year, from 01/10/2020, I have a consumption of around 19 kWh, whereas in my head, it should have been around 000.

And indeed, when I analyze, day by day, I have a figure close to 10...

What does it mean, head?

[phil59]

This is the consumption I have in mind, according to my bills, so consumption, in previous years.

From head, it is about 10 kWh per year that I consume, with sometimes, 000, and sometimes about 9000 ....

10 is a rounded number I have in mind...

When I take the consumption, day by day of ENEDIS from 1/10/2020 to 31/09/2021, I find 9763 kWh, which for me is consistent, not 19 kWh, total per hour..

So why, I don't know, but the file isn't correct, or there's something I don't know, which is very possible.

But for my analysis, per hour, I can't use it....

I do not understand. You mean "previous years". But in previous years you didn't have your Kona with which you obviously drive a lot?

For almost 10 years, I have been driving an EV.

Since 2015, we have 2 EVs at home, and since 2018, no more thermal vehicles.

To situate, with the zoé, for example, over 26 months, we have greatly exceeded 50 km (000 or 51 km)....

With one of the peugeot ion, about 60 km in 000 years ....

But the more you drive, it means that at the same time, you go further, and charge a little less at home, like 25 km, more than 000 at home, and maybe the rest outside. , but 15 km safe outside the house.

Even with the ion, which has 100 km of autonomy, we have already done about 400 km in the day, and therefore necessarily charge outside the house.

So the average of 15 km per year loaded at home is safe, maybe more ....

In fact, in a detached house with a need for domestic hot water, storing solar energy in batteries seems to be an economic and technical nonsense!
It is in fact much cheaper and simpler to store energy in the hot water tank: this is called an electric heater, €180 for 200 L at casto or LM. Moreover, in summer when there is sunshine, hot water needs are the main electricity demand, so why store for other minimal needs...........
The trend is towards the development of domestic hot water - for reasons of hygiene, we wash more, well I hope - and on the other hand the heating needs are increasingly lower (we insulate more, well I hope )..........

Everything can depend on the number of kWp you have.

My situation has changed, and with the tempo subscription, which already saves me more than €700 per year on my bill, this summer I will connect around 7 kWh of recovery lead battery, not intended for that, to give back around 2-3 kWh on red days, when the batteries are full.
Batteries not effective, but free, changed after 2 years of normal use, with a "good source"...

This summer, the time to refine the use...

[sicetaitsimple]

If the batteries are free, that actually changes everything....
