If if we are in a regulatory bottleneck... and the lobbies make the rules as you know! At least they weigh on it!

There is a difference between an off-grid house which has never been connected and a house which is disconnected overnight ... I imagine that neither the supplier nor the distributor will like it!

To be confirmed if it is really prohibited ...

But before that you have to have 10 to put in a battery ...

Profitable after how many years?

It is legal for EDF to cut you off.
All you have to do is take the lead.

Off grid it is rather continuous when the large inverters are alternative.
We must study on a case-by-case basis and generalize a set. And there's more than ...

Easy you divide the overall investment by your annual bill ... In my case, battery + panel = 15 for 000 € of annual bills ... we would be 750 years old ...

To be corrected by possible maintenance problems and the inevitable increase in the cost of electricity ...

So it's still a long time, but what satisfaction to burn a gram of gas, coal or uranium! And to enrich a system that is not necessarily honest with regard to the environment!

20 years ... lifetime of batteries (and cells)? : Cheesy:
No need to say, it looks very profitable to me.

Absolutely: as I said it is they who set the rules! : Cheesy:

There is a nuance between "we cut you" and "you cut"

20 years ... battery life? : Cheesy:


It's a bit like that ... but we didn't take into account the climate cost! : Cheesy:

These are given for 6000 cycles or 16,5 years at the rate of one cycle per day (not necessarily the case ...)

The 25 to 30 years of battery life are playable.

Obviously we lack perspective!

And don't forget that a battery is considered HS when it has lost only 20% of its initial capacity!

750 € annually is a pretty small bill eh! I live almost all the time alone and am thrifty! By cons I pay € 0,3 per kWh ...

Erratum my last regularization I was at 1700 kWh so 510 € per year!

What a ball this Guy. Over 20 years you lose 10% of the maximum HP.
You install 3100Wh instead of 3000Wh and 20 years later you have 2900Wh. And distributed for 20 years of Guy: in 20 years your PV are dead. No Guy: 2700Wh after 40 years.
And in 40 years Guy will say ...

Given your experience in the field, you must be at least 80 years old. : Cheesy:
