3kWc auto conso in Bujaleuf

Messagepar pbosgraaf » 18 févr. 2018 11:27

Hi,

We bought a house in Bujaleuf (87) and i'm researching installing a PV system on the roof.
My French writing is not very good so i hope it's ok for me to write in English.
You can write me back in French i can understand it ok.

I read: http://doc.gppep.org/guide/GPPEP-guide- ... mation.pdf

I'm currently planning the installation and would like to have some help checking my plan.
We want to go for a 2kWc installation for autoconsumation without resale of surplus.

My plan:
1. Before i start EDF needs to replace the meter for a digital meter (Linky?)
- I can do this online: https://particulier.edf.fr
2. Get planning permission (déclaration préalable de travaux)
3. Sign an agreement with ERDF indicating that i will inject into the network
- Need certificate of inverter/converter (conformityt: VDE-0126-1-1)
- Do i need a certificate of the PV panels?
- No need of consule conformity certificate if connected to existing outlet behind 30mA breaker. (Une prise existante)
- I can do online: https://connect-racco.enedis.fr/prac-internet/login/
- More information about the proces: http://www.enedis.fr/produire-de-lelectricite
4. Inform insurer, Vous aurez besoin d'une attestation d'extension de votre Responsabilité Civile pour la mise en service d'une installation
5. Technical requirements
- Existing outlet needs to be behind a 30mA differential circuit breaker
- If using single inverter a DC-switch should be installed between the inveter and the panels
- The solar panels and framework should be grounded
- Clear labels on all cables
6. Take the system in production


Merci,
Peter

2 is the first to do ! go to the town hall and ask for the right paper and procedure and get the '' recepice de depot ''

then go to https://connect-racco.enedis.fr/prac-internet/login/ and ask for a connection

no need of certificat for panels

a DC-switch should be installed : MUST ! be installed in accordance with rules UTE15 712-1
The solar panels and framework should be grounded : MUST ! be installed in accordance with rules UTE15 712-1

1. Before i start EDF needs to replace the meter for a digital meter (Linky?)
- I can do this online: https://particulier.edf.fr


no ENEDIS will replace the meter ( and put a linky )

autoconsumation without resale of surplus


in this case no contract with EDF , only with ENEDIS

Thanks for the help, it turns out my english it not that great too :-)
Should = must, thanks for the correction, and good to know the steps in the plan are ok, just the wrong order.
I will start with the permits next week, thanks again!

One last question about autoconso calculation in the linky, i could not find this in the guide may be you can help me again?
We have a 9kva 3 phase connection with EDF.
If i put the solar inverter on 1 single phase how does auto conso work on the other phase?

Example:

Usage:
L1 - 100w
L2 - 100w
L3 - 100w

Generation:
L1 - 300w

Will autoconso calculate my usage as 0w and waste 0w (sum of all generation - sum of all usage)
Or will autoconso calculate my usage as 200w and waste 200w? (sum of generation on same phase - sum of usage on same phase)

Ofcourse i could go for a 3 phase inverter, but i just want to know how it works before i buy.

Thanks!
Peter

the tri phases linky adds all the values an you ( and ENEDIS ) get only one index of energy.

Usage:
L1 - 100w
L2 - 100w
L3 - 100w

Generation:
L1 - 300w

the result will be : 0 kWh injection

note : it is only for injection , for consumption you will have several index depending on the hour and season ( HP , HC , bleu, blanc , rouge )

Thanks for the answer.
We went to the Marie office last week to apply for permit, now we have to wait.
She told us that the planning commission might demand an in-roof system because of how it looks.
But we live on a farm road with the next neighbor 250m away, very strange :?:

We really don't want an in-roof system because of possible leaks in the roof.
My question, if we do not get planning permission to put the panels on the roof, is it allowed to place the panels (without permission) on the ground level in our garden?

Thanks again

Yes you can, no more than 1.80 meter high ...no papers, no administration, nothing to do...

But I don't understand why in roof...for the Mairie of your town or village...!

I don't understand too.
They told us it was because of how it looks, they want to keep the traditional look of the village.
Hopefully it's a mistake and we will get the permit soon.

Hi,

We already received the permit, much quicker than i expected!
My next step is to make a auto conso connection request at the Enedis website, so i read the contract:
http://www.enedis.fr/sites/default/files/Enedis-FOR-RAC_43E.pdf

And on page 5 i read:
Par ailleurs, le Producteur prendra toutes les dispositions nécessaires pour garantir la non-injection d'énergie sur le Réseau BT.


So our plan was to go with the 3kw auto conso installation without selling the surplus.
But now we are not sure because we don't know if it's permitted or not?

If i look at my average power usage for 1 day for example:
Image

So my always-on level is around 250w
My peek usage is 4kw


So my question is, are we allowed to go for the 3kw installation?
Or is only 250w allowed because that's the always-on level?


Thanks!

Bonjour,
Si cette journée est représentative de votre consommation alors oui il faut partir sur une vente du surplus.
Ce sera incontestablement plus rentable.

Hello

in France you can install in "auto consommation" from 1w to 3kw without selling your production ! or surplus

Perhaps 500w or 750w will be enough for you... :?: :?:

You can also put yourself 3 or 4 modules with micro inverters in your garden

If you want to buy a 3kw and sell a part of your production, you must contact a photovoltaic professionnal

Best regards

Thanks for the clarification, but i have a question:

But what does this mean exactly?:
Par ailleurs, le Producteur prendra toutes les dispositions nécessaires pour garantir la non-injection d'énergie sur le Réseau BT.

If i translate it through google translate:
In addition, the Producer will take all the necessary measures to guarantee the non-injection of energy on the LV Network.


So if i go for the 3kw option i will most definitely inject my surplus in the network because it's above my usage.

Yes you're right ! surplus turns on 0,10€ so EDF OA will pay you every year on yours 'surplus' production

Thanks!

I think we have miscommunication, i wish my french was better :lol:

We want to go for auto conso contract without selling our surplus.

If i look at the contract for auto conso it says:
Par ailleurs, le Producteur prendra toutes les dispositions nécessaires pour garantir la non-injection d'énergie sur le Réseau BT.


We want to place a total of 3kw panels on our roof.
This sometimes produces more then we need, other times we use the 3kw ourselves.


With the auto conso contract, without selling the surplus, is this allowed?

Yes it is and you can do it, but you'll give free your production to EDF OA...(the french Enedis will be very happy :lol: :lol: )

So things are going good, planning permission received, enedis connection approved, panels are placed.
I'm currently configuring the connecting device, in my case a SMA Sunnyboy 3.0
When running the installation wizard you get to select a Coutry Standard, according to the manual i have multiple options for France:
http://files.sma.de/dl/1348/SB_SMC_WB_P ... 113160.pdf (page 17)

GER/VDE0126-1-1 Country-specific parameter settings for Germany and France in accordance with DIN VDE 0126-1-1
VDE0126-1-1/UTE Country-specific parameter settings for France in accordance with UTE C15-712-1

I also have the default option which seems to cover a lot of country's including france as well.

Can anyone tell me what option i should use for the country standard?

Thanks!
Peter
