Hello,

Thank you all for your answers, opinions and advice.

I am actually in Switzerland (I have corrected my profile) and obviously the authorizations for the connection of one of these small kits are not the same from one country to another.

On the model that interests me (280 Wp), it says this on the packaging:

As I said before, I'm not looking to get rich, or even a return on investment, but just to lighten my electricity bills a bit, and if this stuff allows me to do it, then I buy .

You all seem to agree that it is a bit expensive and that I should do much better with a product bought in France. If the quality is the same and the connection principle is not a problem, I will take it to you.

To be continued.

So if it is written on it, it is that the injection, via a socket, is authorized!

It was one of the questions we were asking!

[Take it for humor, but I'm surprised by all the laxity in Switzerland !!!]

The question remains, at this level, how far does tolerance go? Can you put 10 kits, out of 10 sockets ???

To know how much this will reduce your bill, you have to estimate how much of the production will lower your consumption and how much will be reinjected "free" because not consumed at the time it is produced. This is where it will play out!

Basically, what consumption can you "concentrate" on a niche favorable to PV: sunny days from 10 am to 15 or 16 pm ...

I don't remember if you ever mentioned a meter / recorder. Undoubtedly, to have a more precise answer than the only "pif", you would need some records of your "typical" consumption, at different times of the year: summer, autumn, winter ....

Me too ! As you say, in general we are the champions of strict standards and various prohibitions ... But there are exceptions, obviously (for how long?)

Here, it's not stupid ...

I do not think that with such a small power there will be electricity reinjected for free. I think there is always a consumer in action in the house (my wife has her office at home, with computer, printer, etc, etc ...), or an LL or LV, whose consumption will be sufficient for swallow the production of the photovoltaic kit, whatever it is.

Yes, but I only have the main meter (and another smaller one for the boiler and its accessories, as you know).

Again, I think that the power of the kit is sufficiently low to be able to be used in full and at any time (when it produces, of course).

It is an important element. Because production is a kind of hat curve, with a maximum around solar noon (13 or 14 p.m.).

At home, where there is often no one, where I hunt for watches, I am not sure that I will consume ... But I admit not having "estimated" my background noise, especially the circulator of the THIS !

So I have the feeling - to verify - that I will inject 3/4 for free (because I don't have an LL or LV tour every day either - I have just acquired A +++ with delayed start, so it would be playable "technically", but not every day).

Hello to everybody,

I find this thread very interesting and I like the idea of ​​self-consumed power!
afterwards you should not want a return on investment because given the prices for the moment nothing can be amortized in a short time, but just the idea of ​​being able to reduce its consumption a little ...

on another site, or here I can't find it anymore, I saw a link to a site.
I was consulted, the prices are much more interesting than at gsb.
the idea is apparently the same.

[Url] mices.fr [/ url]

but with 250wc we can consider a saving of around 20 € annually, which is not huge ...
but very interesting from an econologist point of view.


EDIT: in fact I just found or I had already seen this site ...
that's what forum on the front page.
well I leave it anyway.
but I like the idea, it should just happen to reduce the purchase price, I think that around 300 € 250Wp we will arrive at something very interesting, we could take 2 panels and reduce our bill by about 50 € / year .. we would arrive at something very interesting.

I can't resist the urge to quote Coluche who said:
"the Swiss flag, it is nevertheless 2 directions prohibited one on the other"

I thought I knew Coluche well, but I didn't know this one.


Basically, I would like us not to oppose two options:

a) the "3hWc" kit [this power for regulatory reasons - maximum of which is subsidized at almost 30 cents; without taxes], with which we can "neutralize" your annual average consumption, of course playing "collective" within a "network" (which I hope will be "intelligent" one day): I inject when I have too much, I "pump" when I am lacking ...

b) the mini-kit, which compensates for a - small - part of consumption, except for an individual approach of the "radical decrease" type, if there is a measurable consumption in the "slots" of production (10 to 15 or 16 h). .


The 1st has more complications, requires a substantial down payment, but weighs, if it multiplies, on the balance of a country ... It is a little "headache" (in particular how to find an honest installer, competent serious and reasonable on the price - does this exist?)

The second is more of a "gesture" on the fringes, which is not open to criticism. But even if this were to become widespread, the bulk of production would still come from "operators". But that is very simple!

"Economically" is roughly "kif-kif" (but with significantly different down payments!).

Well, the economic interest is related to the sums involved ...

20 euros is 150 kWh.

I use 3 kWh per year (000 3 years ago) ... This should drop further (two A +++ devices recently acquired).

This would therefore have an "impact" of around 5% ...

I find that it ultimately makes a lot of money for so little ...

I always favor the option of putting 11 to 12 euros for a 000% impact (in overall balance over the year - at home, by chance, 100 kWp would produce the 3 kwh that I consume or a little more !].

But according to what I just wrote, I do not criticize. I illustrate a thought ...

Yes, I agree with that.

But electricity is not (for the moment) cheap in France. It seems to me that the kWh is at 12 cents, right?

So this kit would save you € 360 per year, and it would therefore be "reimbursed" in ... 33 years.

The panels will probably last this time, but what about the batteries?

The price per kWh in Switzerland is significantly more expensive (0.2407 CHF, or 0.1926 €, the RSI would be a little faster, but then again, what about the price and the lifespan of the batteries?

especially no batteries in a self-consumption device.
you just have to produce the equivalent of the "background noise" of his consumption.
