You surprise me a little Remundo; over the last 3 months, in summer therefore, I produced 1000 KWh and consumed double it (despite an absence of 3 weeks)

Ben you probably your ECS electricity not?

But 2000 kWh on 3 summer months is still a lot ... even with the ECS ...

Did you chase the watches?

It is true that my hot water balloon is old (+ 20 years) and it may be a little too much food; will see

Connect an econometer to it ...

If you are not yet equipped: https://www.econologie.com/shop/prise-el ... p-238.html

Normally you should consume roughly ten kWh per day in DHW for a family of 4 ...

"Normal" electricity needs. Those who heat everything with electricity, that's another problem. :P

Me who found that I produced little with my 400kWh / month over the last 3 months ...

I agree with Remundo, I consumed 4000kWh / year of electricity (gas heating) before driving in electric cars.

Yes Citro,

for those who want to drive in addition in EV, it will be necessary to budget approximately for 15 km / year: 000 kWh

Schematically, an installation of 3 + 3 = 6 kWp (around 60 m²) allows complete energy self-sufficiency (transport + domestic) Excluding heating

If we reached 2 or 3 € / Wp installed, we realize that 12 000 € would be excellently placed for 20 years and more.

Note *: provided that it is connected to the network to manage power peaks / troughs.

If you go to the BDPV site, you will see that you are in the middle of production in Bordeaux facilities; in Moselle we have done a little less well than you in the last 3 months.
Then it depends a lot on the outside temperature, the orientation, the inclination, the integration system and the color of the panels (black loses efficiency compared to blue)

Hello Remundo,
by hollow do you mean among other things the nights? the price of the remaining storage for the moment, if not unaffordable, very expensive.
